Description

Technical Field

[0001] The present application belongs to the field of satellite positioning technology, and in particular, relates to an ephemeris collection method, device, equipment, computer-readable storage medium and computer program product. Background Art

[0002] During the satellite ephemeris collection process, the bit error rate of the parsed navigation message increases due to the weakening of the satellite signal strength. The increased bit error rate makes the ephemeris verification error very common. In order to accurately realize the ephemeris collection, the ephemeris content with errors must be collected and verified again. However, the currently commonly used ephemeris re-collection scheme has a slow comparison speed, which affects the overall ephemeris collection speed. Summary of the invention

[0003] The embodiments of the present application provide a method for collecting ephemeris and related devices, which can solve the problem in the prior art that the speed of overall ephemeris collection is affected due to the slow speed of re-collecting and comparing ephemeris.

[0004] On the one hand, an embodiment of the present application provides a method for collecting ephemeris, the method comprising:

[0005] In the process of collecting subframe ephemeris, if the current subframe fails verification, determining whether there is a verification template corresponding to the current subframe;

[0006] When there is no verification template corresponding to the current subframe, re-collecting the subframe ephemeris, the current subframe being the verification template;

[0007] When there is a check template corresponding to the current subframe, obtaining a detection word in the check template and a word to be tested in the current subframe, the detection word is in a check failure state, and the word to be tested corresponds to the detection word;

[0008] Verifying the word to be tested corresponding to the detection word in sequence, and comparing the detection word with the ephemeris parameters in the word to be tested corresponding to the detection word whenever it is detected that the word to be tested fails the verification, so as to obtain the verification result of each detection word;

[0009] The ephemeris collection result of the current subframe is obtained according to the verification result of each detection word.

[0010] With such a setting, the ephemeris parameters can be used as the minimum comparison unit, and only the sequences related to the ephemeris can be focused on, which can improve the comparison speed during the ephemeris re-collection scheme and greatly improve the success probability of ephemeris collection, thereby solving the problem in the prior art that the overall ephemeris collection speed is affected by the slow comparison speed of ephemeris re-collection.

[0011] Optionally, the checking the words to be tested corresponding to the detection words in sequence, and comparing the detection word with the ephemeris parameters in the words to be tested corresponding to the detection word whenever it is detected that the word to be tested fails the check, to obtain the check result of each detection word, comprises:

[0012] Selecting target detection words from the detection words in sequence;

[0013] Whenever the target detection word is selected, a first check is performed on the word to be detected corresponding to the target detection word;

[0014] When the first check passes, the check result of the target detection word passes, and the next target detection word continues to be selected until all the detection words are selected;

[0015] When the first check fails, a second check is performed on the target detection word and the ephemeris parameters in the word to be detected corresponding to the target detection word to obtain a check result of the target detection word, and the step of continuing to select the next target detection word is executed.

[0016] In this example, by selecting the target detection words one by one, the detection words that are still in the failed verification state in the verification template can be selected for verification, and the process of how to obtain the ephemeris collection result of each detection word in the failed verification state relative to the word to be tested in the current subframe through the first verification and the second verification is further clarified. This improves the comparison speed of each detection word in the process of re-collecting subframes, and the success rate of ephemeris collection for each detection word is improved.

[0017] Optionally, obtaining the verification result of the target detection word includes:

[0018] When the second check passes, the check result of the target detection word is passed;

[0019] When the second check fails, the check result of the target detection word is failed.

[0020] Optionally, after the verification result of the target detection word is passed, the method further includes:

[0021] Replacing the target detection word selected in the verification template with the word to be detected corresponding to the target detection word;

[0022] The target detection word is set to a verification passed state.

[0023] After replacing the target detection word, it is set to the verification passed state. If the ephemeris of the current subframe is not collected successfully, it is not necessary to verify the target detection word when the ephemeris is collected again later. This can speed up the recollection of subsequent subframes and reduce the cumulative number of verifications of the correct detection word.

[0024] Optionally, obtaining the ephemeris collection result of the current subframe according to the verification result of each of the detection words includes:

[0025] When the verification result of any of the detection words fails, the ephemeris collection of the current subframe fails;

[0026] When the verification results of all the words to be tested are passed, the ephemeris collection of the current subframe is successful.

[0027] By counting each detection word in the verification template that is in a verification failure state, relative to the verification result of the corresponding word to be tested in the current subframe, the ephemeris collection result of the current subframe can be identified, thereby dividing the re-ephemeris collection of the subframe into ephemeris collection verification of each detection word, thereby improving the speed of the overall ephemeris collection.

[0028] Optionally, after the ephemeris collection of the current subframe fails, the method further includes:

[0029] Re-collect the sub-frame ephemeris.

[0030] Optionally, in the process of collecting subframe ephemeris, the method further includes:

[0031] If the current subframe verification passes, the current subframe ephemeris collection is successful.

[0032] On the other hand, an embodiment of the present application provides a method and device for collecting ephemeris, the device comprising:

[0033] A judgment module, used for judging whether there is a verification template corresponding to the current subframe if the current subframe fails to pass the verification during the process of collecting the subframe ephemeris;

[0034] A collecting module, used for re-collecting the subframe ephemeris when there is no verification template corresponding to the current subframe, the current subframe being the verification template;

[0035] An acquisition module, configured to acquire, when there is a check template corresponding to the current subframe, a detection word in the check template and a word to be tested in the current subframe, the detection word being in a check failure state, and the word to be tested corresponding to the detection word;

[0036] A verification module, used for verifying the word to be tested corresponding to the detection word in turn, and comparing the detection word with the ephemeris parameters in the word to be tested corresponding to the detection word whenever it is detected that the word to be tested fails the verification, so as to obtain a verification result for each detection word;

[0037] The determination module is used to obtain the ephemeris collection result of the current subframe according to the verification result of each detection word.

[0038] On the other hand, an embodiment of the present application provides a method and device for collecting ephemeris, the device comprising:

[0039] a processor and a memory storing computer program instructions;

[0040] When the processor executes the computer program instructions, the ephemeris collection method as described above is implemented.

[0041] On the other hand, an embodiment of the present application provides a computer storage medium, on which computer program instructions are stored. When the computer program instructions are executed by a processor, the ephemeris collection method as described above is implemented.

[0042] On the other hand, an embodiment of the present application provides a computer program product. When instructions in the computer program product are executed by a processor of an electronic device, the electronic device executes the ephemeris collection method as described above.

[0043] In the ephemeris collection method, device, equipment, computer storage medium and computer program product of the embodiment of the present application, when there is a verification template corresponding to the current subframe, the detection word in the verification template that is in a verification failure state and the word to be tested corresponding to the detection word in the current subframe can be obtained; by verifying the word to be tested corresponding to the detection word, the verification result of each detection word is confirmed, and then the ephemeris collection result of the current subframe is obtained according to the verification result of each detection word. Because a secondary verification process is set when the word to be tested corresponding to the detection word is verified in sequence, that is, when the verification of the word to be tested fails each time, the ephemeris parameters in the detection word and the word to be tested corresponding to the detection word are compared to confirm the verification result of the detection word in this case, such a setting can use the ephemeris parameter as the minimum comparison unit, only focus on the sequence related to the ephemeris, can improve the comparison speed of the ephemeris re-collection scheme, greatly improve the success probability of ephemeris collection, thereby solving the problem that the overall ephemeris collection speed is affected by the slow comparison speed of the ephemeris re-collection in the prior art.

[0049] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0050] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0051] As described in the background art, when the bit error rate of the parsed navigation message increases, the navigation message verification will fail, thereby affecting the complete ephemeris collection.

[0052] In order to solve the problem that the navigation message cannot pass due to the increased bit error rate and the accuracy of ephemeris collection is affected, it is necessary to re-collect the ephemeris content with verification errors, and then splice the re-collected ephemeris content with the successfully verified ephemeris subframes in the previously collected ephemeris content, that is, use the splicing idea to get a complete ephemeris.

[0053] In the process of recollecting the ephemeris content, the prior art first initializes the state of each detection word, and then compares the original bit information of the collected Nth round detection word and the Mth round detection word, N≠M, thereby obtaining the correct bit information, and then confirming that the detection of the detection word is completed. After all detection words in the current subframe are detected, the recollection of the ephemeris of the current subframe is completed.

[0054] Although the prior art also realizes complete ephemeris collection by recollecting subframe ephemeris based on splicing frames, it compares all detection words in the subframes. Therefore, the subframe splicing and comparison method of the prior art still has the following disadvantages.

[0055] On the one hand, some detection words in the subframe do not contain ephemeris information. For example, in the D2 navigation message of the BD GEO (Beidou Geosynchronous Orbit) satellite, in the subframe containing ephemeris, only the upper 150 bits (i.e., the upper 5 words) contain ephemeris information, and even if the 150th bit message is wrong, it will not affect the ephemeris collection.

[0056] On the other hand, when the prior art re-collects the ephemeris content, the unit of ephemeris comparison is the detection word, and some parts of the information in the detection word are irrelevant to the ephemeris information. The D2 navigation message of the BD GEO satellite is still used for further explanation. Except for the first detection word, the other detection words are 22-bit ephemeris information + 8-bit check information. If the bit of the check information has a bit error, it will not affect the ephemeris collection.

[0057] In summary, the comparison and verification method of the prior art ephemeris content re-collection solution objectively has the problem that the re-collection solution comparison speed is slow, which affects the overall ephemeris collection speed.

[0058] It is on the premise of discovering this technical problem that the inventor of the present application has proposed a new ephemeris collection method and related device for the purpose of collecting correct ephemeris. In the process of re-collecting ephemeris subframes, the ephemeris parameters are used as the minimum comparison unit and the bit sequence related to the ephemeris is focused on, thereby solving the problem of slow comparison speed of the re-collection scheme and improving the probability and speed of successful ephemeris collection.

[0059] The following first introduces the ephemeris collection method provided in the embodiment of the present application.

[0060] Figure 1FIG. 1 is a flow chart of a method for collecting ephemeris provided by an embodiment of the present application. Figure 1 As shown, the ephemeris collection method provided in the embodiment of the present application includes the following steps:

[0061] S101. In the process of collecting subframe ephemeris, if the current subframe fails verification, determine whether there is a verification template corresponding to the current subframe; if not, execute S102; if yes, execute S103.

[0062] S102: re-collect the subframe ephemeris, wherein the current subframe is the verification template.

[0063] S103: Acquire a detection word in the verification template and a word to be tested in the current subframe, wherein the detection word is in a verification failure state and the word to be tested corresponds to the detection word.

[0064] S104, sequentially verifying the words to be tested corresponding to the detection words, and whenever it is detected that the word to be tested fails the verification, comparing the detection word with the ephemeris parameters in the word to be tested corresponding to the detection word to obtain a verification result for each detection word.

[0065] S105: Obtaining an ephemeris collection result of the current subframe according to a verification result of each detection word.

[0066] This application is applicable to the collection of ephemeris for at least one of Beidou geosynchronous orbit satellites, Beidou inclined geosynchronous orbit satellites and global positioning system. It is particularly applicable to the collection of Beidou geosynchronous orbit satellites, because compared with the 20ms width of navigation messages of Beidou inclined geosynchronous orbit satellites and global positioning system, the width of navigation messages of Beidou geosynchronous orbit satellites is only 2ms, which is more prone to navigation message errors.

[0067] The present application can, in the process of collecting subframe ephemeris, obtain the detection word in the verification template that is in a failed verification state and the word to be tested corresponding to the detection word in the current subframe when there is a verification template corresponding to the current subframe; confirm the verification result of each detection word by verifying the word to be tested corresponding to the detection word, and then obtain the ephemeris collection result of the current subframe according to the verification result of each detection word. Because a secondary verification process is set when verifying the word to be tested corresponding to the detection word in sequence, that is, when each time the word to be tested is detected to fail the verification, the ephemeris parameters in the detection word and the word to be tested corresponding to the detection word are compared to confirm the verification result of the detection word in this case, such a setting can use the ephemeris parameter as the minimum comparison unit, only focus on the sequence related to the ephemeris, can improve the comparison speed of the ephemeris re-collection scheme, greatly improve the success probability of ephemeris collection, thereby solving the problem of the prior art that the slow comparison speed of ephemeris re-collection affects the overall ephemeris collection speed.

[0068] In some embodiments, before performing subframe verification in S101, each subframe is divided into multiple detection words according to ICD (Interface Control Document), the number of the detection words is known, and the polarity of each detection word is also detected, so that the polarity of each detection word is accurate, thereby ensuring that correct ephemeris information is obtained after subsequent ephemeris parameter comparison and verification.

[0069] In the process of ephemeris collection in S101, multiple sub-frame ephemeris can actually be collected at the same time. The sub-frame ephemeris can be used as a verification unit during the collection. If all the sub-frame ephemeris being collected pass the verification, the ephemeris collection is completed.

[0070] That is, for each subframe ephemeris, the subframe can be used as a verification unit. If the current subframe passes the verification, it means that the current subframe ephemeris is completely correct and the current subframe ephemeris is successfully collected. If the current subframe fails the verification, the frame splicing strategy needs to be adopted to re-collect the subframes that failed the verification.

[0071] Before recollecting the subframe ephemeris, it can be determined whether there is a verification template corresponding to the current subframe. It should be noted that each subframe that fails verification actually has its corresponding verification template, and the verification template uses the subframe when the current subframe fails verification for the first time as the reference template. Subsequently, by recollecting the ephemeris of the subframe that fails verification, the detection words that fail verification (fail verification) in the verification template can be rechecked one by one, so as to realize the update of the verification template.

[0072] Therefore, in S102, when there is no verification template corresponding to the current subframe, indicating that the current subframe fails the first verification, the current subframe can be used as a verification template to collect the subframe ephemeris again.

[0073] When there is a verification template corresponding to the current subframe, it indicates that there is a record of verification failure in the current subframe before, and the verification template and the word in the current subframe can be verified.

[0074] In some examples, the method of performing verification using detection words as comparison units is actually different from the prior art. The verification template of the present application is marked with the status of each detection word, including a verification failed status and a verification passed status. The present application only compares the detection words in the verification failed status.

[0075] Exemplarily, the verification failure status can be marked as "1", and the verification pass status can be marked as "0". Of course, other characters and / or numbers can also be used for marking. The status word settings of "0" and "1" of the detection word can quickly find the detection word that has failed the verification, which is convenient for quickly implementing the detection word verification.

[0076] It should be noted that the verification failure status can be marked when the verification template is first obtained (i.e., the current subframe fails the first verification). At the same time, when the subframes corresponding to the verification template are subsequently repeatedly collected again, the permissions and conditions can also be set to modify the status of the detection word. The verification status of the word in the verification template can be distinguished by the status mark of the detection word, so that in the process of subsequent subframe recollection, only the detection word that failed the verification is targeted.

[0077] Since the current subframe corresponds to the verification template, the word to be tested in the current subframe at the same position as the detection word that failed the verification in the verification template can be extracted, and the word to be tested is compared and verified with the detection word.

[0078] After obtaining the detection word and the corresponding word to be detected in S103, the words can be checked one by one. In the word-by-word checking, firstly, a check is performed on the word to be detected. If the check fails, the detection word and the ephemeris parameters in the word to be detected corresponding to the detection word are compared to realize a secondary check; thus, the check result of each detection word in the check template is finally obtained by combining the primary check and the secondary check.

[0079] It can be understood that, since a secondary verification step focusing on the ephemeris parameters is added when the first verification fails, the ephemeris parameters in the detection word and the word to be tested are used as the minimum verification unit, and other parameters in the word that are not related to the ephemeris information are not paid attention to, and the verification failure caused by parameter errors that are not related to the ephemeris information is not considered, the success rate of ephemeris collection of a single detection word relative to the current subframe can be improved without affecting the correctness of the actual ephemeris collection. Ultimately, the overall speed of comparing the ephemeris re-collection scheme that obtains the ephemeris collection result of the current subframe based on the test results of all detection words is improved, and thus the speed of complete ephemeris collection is improved.

[0080] In some embodiments, see Figure 2 In S104, the words to be tested corresponding to the detection words are verified in sequence, and when it is detected that the word to be tested fails to be verified, the detection word is compared with the ephemeris parameters in the word to be tested corresponding to the detection word to obtain the verification result of each detection word, which may include:

[0081] Step S201, selecting a target detection word from the detection words in sequence;

[0082] Step S202, each time the target detection word is selected, performing a first check on the word to be detected corresponding to the target detection word;

[0083] Step S203, when the first check passes, the check result of the target detection word passes;

[0084] Step S204, continue to select the next target detection word until all the detection words are selected;

[0085] Step S205, when the first check fails, a second check is performed on the target detection word and the ephemeris parameters in the word to be detected corresponding to the target detection word to obtain a check result of the target detection word, and then step S204 is continued.

[0086] In this example, the selection of the target detection word is implemented to trigger the verification of the word to be tested corresponding to the target detection word in the current subframe, or the verification of the word to be tested is compared with the ephemeris parameters, and finally the verification result of each detection word is obtained.

[0087] The target detection word can be selected randomly or according to the order of the detection words in the verification template. When performing the first verification on each detection word, the word verification technology of the prior art can be referred to, which will not be described in detail here.

[0088] During the second verification, the comparison of the ephemeris parameters in the target detection word and the word to be tested corresponding to the target detection word can be to compare whether all the ephemeris parameters in the target detection word and the corresponding word to be tested are completely consistent. If they are completely consistent, the second verification is passed, and the ephemeris collection of the target detection word is successful relative to the word to be tested in the current subframe; if they are not completely consistent, the second verification fails, and the ephemeris collection of the target detection word fails relative to the word to be tested in the current subframe.

[0089] In this example, by selecting the target detection words one by one, the detection words that are still in the failed verification state in the verification template can be selected for verification, and the process of how to obtain the ephemeris collection result of each detection word in the failed verification state relative to the word to be tested in the current subframe through the first verification and the second verification is further clarified. This improves the comparison speed of each detection word in the process of re-collecting subframes, and the success rate of ephemeris collection for each detection word is improved.

[0090] In other embodiments, when the verification result of the target detection word is passed, the target detection word selected in the verification template may be replaced with the word to be tested corresponding to the target detection word; and the target detection word may be set to a verification passed state.

[0091] It can be understood that when the verification result of the target detection word is passed, it actually means that the word to be tested corresponding to the target detection word in the current subframe has passed the verification, and the correct ephemeris information is stored in the word to be tested; or, when the verification result of the target detection word is passed, the ephemeris parameter information of the word to be tested and the target detection word is consistent, and the ephemeris parameters are correct.

[0092] After that, by replacing the target detection word in the verification template, the verification template can be updated to make it closer to the subframe with the correct final ephemeris. After replacing the target detection word, it is set to the verification pass state. If the ephemeris of the current subframe is not collected successfully, when the ephemeris is collected again later, it is not necessary to verify the target detection word, which can speed up the recollection of subsequent subframes and reduce the cumulative number of verifications of the correct detection word.

[0093] In some optional examples, in S105, obtaining the ephemeris collection result of the current subframe based on the verification result of each of the detection words may include: when the verification result of any of the detection words is failure, the ephemeris collection of the current subframe fails; when the verification results of all the words to be tested are passed, the ephemeris collection of the current subframe is successful.

[0094] It should be noted that in the above example, the verification of the detection words in the verification template that are in the failed verification state relative to the current subframe is introduced. However, when the verification results of all detection words are passed, it means that the verification status of all detection words in the verification template can be updated relative to the current subframe.

[0095] Still taking the above-mentioned status word of the failed verification state as "1" and the status word of the passed verification state as "0" as an example for explanation. When all the detection words with the status of "1" can be updated and become "0", all the detection words in the verification template are correct for ephemeris collection, and the verification template after the updated detection words can be output, and the ephemeris collection of the subframe is completed.

[0096] On the contrary, if the status of any detection word in the verification template is still "1", there are still detection words that have not passed the verification in the verification template. Then, after the target detection word is updated to the word to be tested, the collection of the current subframe ephemeris can be started again until the status of all detection words in the verification template are in the verification passed state.

[0097] By counting each detection word in the verification template that is in a verification failure state, relative to the verification result of the corresponding word to be tested in the current subframe, the ephemeris collection result of the current subframe can be identified, thereby dividing the re-ephemeris collection of the subframe into ephemeris collection verification of each detection word, thereby improving the speed of the overall ephemeris collection.
