These terms are only used to distinguish the same type of information from each other.

Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0049] In this specification, a method for selecting and verifying aerospace sensors is provided. This specification also relates to an aerospace sensor selection and verification apparatus, a computing device, and a computer-readable storage medium, which are described in detail one by one in the following embodiments.

[0050] See also Figure 1 , Figure 1A flow chart of a method for selecting and verifying a space sensor provided according to an embodiment of the present specification is shown, which specifically includes the following steps.

[0051] Step 101: Determine a resolution parameter and a range parameter, and determine a target sensor based on the resolution parameter and the range parameter.

[0052] In one possible implementation, a performance calibration is performed on the noise of the target sensor to determine a performance calibration result, including: calibrating the noise of the target sensor to determine a noise calibration result; performing an accuracy calibration based on the noise calibration result to determine an accuracy calibration result; and determining a performance calibration result based on the noise calibration result and the accuracy calibration result.

[0053] In practical applications, see Figure 2 According to the mission requirements, the test indicators should be selected first, mainly including the resolution selection and the range selection. These two indicators must first meet the requirements of the technical requirements. Because according to the needs of the navigation system, other indicators can be designed in the later stage, and these two indicators cannot be replaced by later measures. In addition to selecting the resolution according to the technical indicators of the product itself, it must also be verified. The range is selected according to the design indicators. After the resolution and range are selected, the basic verification of the indicators is first performed using the ground verification method.

[0054] Specifically, resolution test: First, in an environment with background vibration noise that is 10 times or lower than the resolution, the frequency range of the sensor should be considered for environmental selection. Test the sensor's lowest resolution within the working frequency band. The data acquisition equipment should also have corresponding test capability requirements. In order to have a good signal-to-noise ratio, the background noise of the channel should be lower than 10 times the test level. Range: The range is selected according to the characteristics of the task. Generally, it should be higher than 2 times the estimated maximum level of the task. This parameter depends on the design principle of the sensor itself. The standard signal source can be used to calibrate the maximum level for verification.

[0055] Step 102: Perform performance calibration on the noise of the target sensor and determine the performance calibration result.

[0056] In practical applications, the sensor is calibrated and two indicators of test accuracy are calibrated at a conventional level. The resolution of the sensor can be tested in a cave, where the background noise reaches 1*10-7g and the noise of the data acquisition system reaches 1*10-8. After completing the above indicators, the dynamic range of the sensor and the linearity of the two accuracy indicators are calibrated at a conventional level. After completing the conventional level calibration, a small level calibration is also required.

[0057] Specifically, the measurement accuracy test: the test accuracy is measured from two aspects: amplitude linearity and dynamic range. The standard signal source calibration method is generally used for test verification. The dynamic range calibration should cover the required frequency band range, and the amplitude linearity should cover all test ranges. After all environmental tests are completed, the measurement accuracy test should be conducted again to ensure the working state of the sensor; according to the working characteristics of the sensor, a separate accuracy test should be conducted on sensitive environmental factors, and accuracy compensation measures should be formulated. Amplitude linearity should generally be better than 5% within the test frequency band. The amplitude range should generally be better than 1% within the range.

[0058] Step 103: Determine physical parameters based on the performance calibration results, and determine physical parameter selection results based on the physical parameters.

[0059] In one possible implementation, physical parameters are determined based on performance calibration results, and physical parameter selection results are determined based on the physical parameters, including: when the performance calibration results meet the requirements, determining weight physical parameters and size physical parameters; and determining physical parameter selection results based on physical parameter boundaries, weight physical parameters, and size physical parameters.

[0060] In practical applications, see Figure 2 After the first step of selection, the weight, size and other physical parameters are selected. The selection of physical parameters is based on the maximum weight and size requirements of the product. If the weight and size do not meet the requirements, iterate back to the first step and select again.

[0061] Step 104: Perform environmental test index verification based on the physical parameter selection result and determine the index verification result.

[0062] In one possible implementation, environmental test indicator verification is performed based on the physical parameter selection results to determine the indicator verification results, including: when the physical parameter selection results meet the requirements, environmental adaptability testing is performed to determine the environmental adaptability capability; wherein the environmental test capability includes mechanical environment, thermal environment and magnetic environment; selection is performed based on the environmental adaptability capability to determine the indicator verification result.

[0063] In practical applications, see Figure 2 , and then proceed to the third step, environmental adaptability capability selection. First, according to aerospace needs, select the environmental adaptability package, and select in the order of force, heat, magnetism, and other environments.

[0064] When the capability does not meet the requirements, or when the environmental adaptability affects the basic measurement indicators, the test indicator verification in this environment should be carried out. When the first step indicator requirements cannot be met, restart the first step. When the first step cannot take treatment measures, such as vibration isolation, thermal coating, temperature control, magnetic protection, etc. Then, comprehensively consider the impact of the treatment measures and restart the second step process.

[0065] In one possible implementation, an environmental adaptability test is performed, including: an environmental adaptability test for a mechanical environment through a sinusoidal vibration test, a random vibration test, and an impact test; an environmental adaptability test for a thermal environment through a thermal cycle test, a storage test, and a thermal vacuum test; and an environmental adaptability test for a magnetic environment through a constant magnetic field environment.

[0066] In practical applications, the mechanical environment adaptability test: the sensor should be able to withstand the mechanical environment of the spacecraft launch phase, and the performance of the sensor remains unchanged in this environment. The mechanical environment test is verified through sinusoidal vibration test, random vibration test and impact test, and the test magnitude and frequency band range are set according to the actual environment experienced. During the test, including the acceptance level and the identification level, whether the sensor is powered can be set according to the working status during the actual launch. The impact test should be carried out in the form of a shock response spectrum control test. Before and after the test, the status of the sensor is tested and checked to ensure the product status.

[0067] Furthermore, thermal environment adaptability test: The thermal environment adaptability test of the sensor includes thermal cycle test, storage test, and thermal vacuum test. In addition to the storage test, the sensor should be in working condition when conducting the test. The test includes acceptance level test and identification level test. The test conditions are set according to the actual temperature environment when working on orbit. The temperature change rate should also be taken into account in the setting of the test conditions.

[0068] Furthermore, magnetic environment adaptability test: The sensor should carry out magnetic environment adaptability test in the initial sample stage, place the sensor in a constant magnetic field environment for testing, and verify the changes in sensor response when the magnetic field is turned on and off.

[0069] In a possible implementation, performing the environmental adaptability test also includes: performing a radiation test and an EMC test.

[0070] In actual applications, other environmental adaptability tests may also be included, which generally include radiation tests and EMC tests. These two types of tests are generally carried out at the initial sample stage. When conducting radiation tests, the amount of radiation received can be calculated based on the product's service life to conduct equivalent tests. During EMC testing, it is necessary not only to simulate the working conditions when subject to electromagnetic interference, but also to simulate the emission to the outside world during operation.

[0071] Step 105: Perform aerospace process verification based on the indicator verification result to determine the aerospace process verification result.

[0072] In one possible implementation, a space process verification is performed based on the indicator verification result to determine the space process verification result, including: when the indicator verification result meets the requirements, determining the on-orbit working environment; and performing a space process verification based on the on-orbit working environment to determine the space process verification result.

[0073] In practical applications, see Figure 2 Finally, when the test adaptability of the third step can meet the requirements, the fourth step of complete comprehensive test verification is carried out. When the fourth step of comprehensive test verification is carried out, all the treatment measures during on-orbit work should be included and the test verification should be carried out according to the standard aerospace process.

This realizes the test assessment of aerospace high-precision sensors on the ground and ensures their reliability in orbit.
