All other embodiments obtained by those of ordinary skill in the art based on the embodiments of this application without creative efforts shall fall within the scope of protection of this application.

[0034] A positioning system is a technology that uses satellites to determine the position of an object, aiming to provide real-time, all-weather, and global navigation services for global users. It has developed from an initial system with low positioning accuracy, inability to perform real-time positioning, and difficulty in providing navigation services to the current global positioning system that can timely locate objects at most times and in most locations. In related technologies, when it is necessary to locate any object, first, the corresponding positioning information is obtained through the positioning system, and then the positioning information is transmitted to the corresponding monitoring platform, so that the monitoring platform can obtain the position of the object in real time. However, in related technologies, in areas with poor network environments, remote mountainous areas, and incomplete base station construction, it is difficult for the monitoring platform to obtain the positioning information of the object, making it impossible to monitor the position of the object and reducing the user experience.

[0035] To solve the above technical problems, the embodiments of this application propose the following technical concept: The inventor considered a positioning system for determining the position of an object constructed by a global satellite positioning system, a microcontroller unit, a low-earth-orbit satellite communication system, and a terminal monitoring center. Based on the global satellite positioning system, a target position statement of the object to be located is sent to the microcontroller unit. The microcontroller unit extracts the longitude and latitude according to the target position statement, encodes the longitude and latitude, and then sends it to the low-earth-orbit satellite communication system. The low-earth-orbit satellite communication system performs parsing processing on the encoded longitude and latitude to send the parsed longitude and latitude to the terminal monitoring center. The terminal monitoring center decodes the parsed longitude and latitude to obtain the longitude and latitude of the object, so that the positioning information of the object can be obtained in a timely manner in areas with poor network environments, remote mountainous areas, and incomplete base station construction, improving the user experience.

[0036] Figure 1 is a schematic structural diagram of the positioning system for determining the position of an object provided by the embodiments of this application Figure 1 。

[0037] As Figure 1 shown, the positioning system for determining the position of an object includes: a positioning terminal 10, a low-earth-orbit satellite communication system 20, and a terminal monitoring center 30. The positioning terminal 10 includes a global satellite positioning system 101 and a microcontroller unit 102.

[0038] The global satellite positioning system 101 continuously generates target location data of the object to be located, determines a corresponding target location statement according to the target location data, and sends the target location statement to the micro control unit 102 .

[0039] In this embodiment, the target location data includes latitude, longitude, altitude and other location data.

[0040] In this embodiment, the target position sentence is a NMEA sentence.

[0041] NMEA is a standard format for transmitting position and time information in global positioning systems and other navigation devices.

[0042] The micro control unit 102 extracts the key sentence in the target position sentence; determines the corresponding longitude and latitude information according to the key sentence; encodes the longitude and latitude information according to a preset base to obtain the encoded longitude and latitude; and sends the encoded longitude and latitude to the low-orbit satellite communication system 20.

[0043] In this embodiment, the key statement is the RMC statement, which is used to determine the longitude and latitude of the object.

[0044] Among them, RMC is a commonly used NMEA-0183 format data, which is used to provide key data such as the positioning information, speed and direction of the receiver.

[0045] In this embodiment, the preset base may be binary, octal or hexadecimal, or other bases.

[0046] Exemplarily, the micro control unit 102 extracts the RMC statement in the NMEA statement; determines the corresponding longitude and latitude information according to the RMC statement; encodes the longitude and latitude information in hexadecimal to obtain the encoded longitude and latitude; and sends the encoded longitude and latitude in an eight-byte data packet to the low-orbit satellite communication system 20.

[0047] The low-orbit satellite communication system 20 parses the encoded longitude and latitude to obtain parsed longitude and latitude; and sends the parsed longitude and latitude to the terminal monitoring center 30.

[0048] Specifically, the low-orbit satellite communication system 20 parses the encoded longitude and latitude to remove incomplete and erroneous data, thereby obtaining the parsed longitude and latitude; and sends the parsed longitude and latitude to the terminal monitoring center 30.

[0049] The terminal monitoring center 30 decodes the parsed longitude and latitude to obtain the longitude and latitude corresponding to the object.

[0050] Exemplarily, the terminal monitoring center 30 decodes the parsed hexadecimal latitude and longitude to obtain the latitude and longitude corresponding to the item.

Through the cooperation among the satellite positioning system, the microcontroller unit, the low-earth orbit satellite communication system, and the terminal monitoring center, the satellite signal coverage is wider, and the anti-interference ability of the positioning system is stronger. It is possible to obtain the positioning information of the item in a timely manner in areas with poor network environment, remote mountainous areas, and incomplete base station construction, etc., to monitor the position of the item and improve the user experience.

[0052] In addition, the positioning system for determining the position of an item provided in this embodiment encodes the latitude and longitude information in hexadecimal through the microcontroller unit to obtain the encoded latitude and longitude; sends the encoded latitude and longitude to the low-earth orbit satellite communication system in an eight-byte data packet, which reduces the data transmission efficiency and the data transmission cost.

[0060] In this embodiment, the positioning chip 10123 supports cooperative positioning of GPS, GLONASS, Galileo, and Beidou multi-mode positioning systems.

[0061] Specifically, the receiving circuit 10121 receives the position data and timestamp propagated by at least four satellites in the multi-mode satellite system 1011 through the right-handed circularly polarized ceramic antenna 10122; and sends the position data and timestamp to the positioning chip 10123.

[0062] The positioning chip 10123 determines the propagation time of the position data according to the timestamp; determines the target position data of the item to be located according to the propagation time and the position data; generates a target position statement according to a preset format protocol for the target position data; and sends the target position statement to the micro control unit 102.

[0065] The low-earth orbit satellite communication module 201 sends the encoded longitude and latitude to the low-earth orbit satellite unit 203 through the left-handed circularly polarized ceramic antenna 202.

[0066] In this embodiment, the operating frequency point of the left-handed circularly polarized ceramic antenna 202 is 1610 - 1626.5 MHz.

[0067] Specifically, the low-earth orbit satellite communication module 201 sends the encoded longitude and latitude through the left-handed circularly polarized ceramic antenna 202 to the low-earth orbit satellite unit 203 at a preset time interval and a preset redundancy number of times.

[0068] Among them, the preset time interval is 5 minutes, 10 minutes or other time intervals.

[0069] Among them, the redundancy number of times is any one of 2 times, 3 times or 5 times, and can also be other numbers of times.

[0070] The low-earth orbit satellite unit 203 sends the encoded longitude and latitude to the satellite data transmission system 204.

[0071] In this embodiment, the low-earth orbit satellite unit 203 is one or more low-earth orbit satellites.

[0076] In this embodiment, the satellite data processing terminal 2042 is a Globalstar platform.

[0077] Among them, the Globalstar platform is the Globalstar system, which has the advantages of low latency, wide coverage and strong anti-interference ability.

[0078] Specifically, the satellite data processing terminal 2042 performs parsing processing on the encoded longitude and latitude to eliminate all redundant, incomplete and incorrect longitude and latitude, so as to obtain the parsed longitude and latitude; and sends the parsed longitude and latitude to the terminal monitoring center 30.

[0079] Among them, the parsed longitude and latitude are longitude and latitude containing complete data.

[0080] In summary, for the positioning system provided in this embodiment for determining the position of an item, the low-earth orbit satellite communication module sends the encoded longitude and latitude to the low-earth orbit satellite unit through a left-handed circularly polarized ceramic antenna at a preset time interval and a preset redundancy number of times. By redundantly sending the encoded longitude and latitude multiple times, the influence of obstacles and the incomplete satellite coverage for a short period can be avoided.

[0081] In addition, for the positioning system provided in this embodiment for determining the position of an item, the receiving circuit receives the position data and timestamp propagated by the multi-mode satellite system through a right-handed circularly polarized ceramic antenna; and sends the position data and timestamp to the positioning chip.
