[0021] It should also be noted that the terms "first" or "second" used in this specification to refer to numbers or ordinals are only used for descriptive purposes and cannot be understood as explicitly or implicitly indicating relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0022] This application provides a positioning system, see Figure 1 , Figure 1 The positioning system 1 of the present application may include: an antenna module 2, a radio frequency front-end module 3, a first positioning module 4, a second positioning module 5 and a switching module 6.

[0023] The radio frequency front-end module 3 is connected to the antenna module 2 , and the switching module 6 is connected to the radio frequency front-end module 3 , the first positioning module 4 and the second positioning module 5 .

[0024] Exemplarily, when the positioning system 1 is working, the antenna module 2 receives satellite signals transmitted from the satellite through the antenna, converts the received satellite signals into electrical signals, and transmits the satellite signals to the RF front-end module 3. The RF front-end module 3 processes the received satellite signals, filters out stray signals in the satellite signals, amplifies and enhances the satellite signals, and improves the signal quality. The switching module 6 is connected to the first positioning module 4 or the second positioning module 5, and transmits the satellite signals processed by the RF front-end module 3 to the first positioning module 4 or the second positioning module 5. The first positioning module 4 or the second positioning module 5 performs further positioning processing on the received satellite signals to obtain positioning information related to position and time.

[0025] The above scheme can receive satellite signals through the antenna module 2 and send the satellite signals to the RF front-end module 3, use the RF front-end module 3 to filter and amplify the new satellite signals, and then pass the satellite signals processed by the RF front-end module 3 to the first positioning module 4 or the second positioning module 5 through the switching module 6 for positioning processing to obtain relevant positioning information such as position and time, and through the switching module 6, the first positioning module 4 and the second positioning module 5 can share the RF front-end module 3 when performing positioning processing.

[0026] In some embodiments, see Figure 1 , Figure 1 The switching module may include an input port 61 , a first output port 62 and a second output port 63 .

[0027] The input port 61 is connected to the RF front-end module 3 , the first output port 62 is connected to the first positioning chip, and the second output port 63 is connected to the second positioning chip, wherein the first positioning chip is arranged on the first positioning module 4 , and the second positioning chip is arranged on the second positioning module 5 .

[0028] The switching module can be a single-pole double-throw switch, wherein a single-pole double-throw switch (Single Throw, Double Pole Switch, referred to as SPDT switch) is a common type of electrical switch, which has a switching rod (or switching button) and three connection points or terminals. The SPDT switch has two fixed position terminals, usually called "COM" (Common) and "NO" (Normally Open), and a movable position terminal called "NC" (Normally Closed). When the switch is in one position, "COM" is connected to "NO", and when the switch is switched to another position, "COM" is connected to "NC". The SPDT switch changes the connection mode of the circuit by the position of the switching rod.

[0029] Exemplarily, when the positioning system 1 is working, when the input port 61 is connected to the first output port 62, a transmission path is formed between the input port 61 and the first output port 62, so that the satellite signal processed by the RF front-end module 3 can be transmitted to the first positioning chip connected to the first output port 62 through the transmission path between the input port 61 and the first output port 62, so that the first positioning chip performs positioning processing to obtain positioning information related to position and time. When the switching module 6 switches the input port 61 to connect to the second output port 63, a transmission path is formed between the input port 61 and the second output port 63, so that the satellite signal processed by the RF front-end module 3 can be transmitted to the second positioning chip connected to the second output port 63 through the transmission path between the input port 61 and the second output port 63, so that the second positioning chip performs positioning processing to obtain positioning information related to position and time.

[0030] The above scheme can select the input port 61 to connect to the first output port 62 or the second output port 63 through the switching module 6, and transmit the satellite signal processed by the RF front-end module 3 to the first positioning chip connected to the first output port 62 through the transmission path between the input port 61 and the first output port 62, or transmit the satellite signal to the second positioning chip connected to the second output port 63 through the transmission path between the input port 61 and the second output port 63, thereby changing the connection mode of the circuit and realizing the selection function of the first chip and the second chip.

[0031] In some embodiments, see Figure 1 , Figure 1 The RF front-end module 3 may include a first filter 31 , an amplifier 32 and a second filter 33 .

[0032] The input end of the first filter 31 is connected to the antenna module 2 , the input end of the amplifier 32 is connected to the output end of the first filter 31 , the input end of the second filter 33 is connected to the output end of the amplifier 32 , and the output end of the second filter 33 is connected to the switching module 6 .

[0033] The first filter 31 and the second filter 33 may be surface acoustic wave filters, wherein a surface acoustic wave filter (SAW Filter) is an electronic device used for filtering and frequency selection, and utilizes the characteristics of a surface acoustic wave (SAW) to implement a signal filtering function.

[0034] The amplifier 32 may be a low noise power amplifier, wherein a low noise power amplifier (LNPA) is an amplifier used to amplify weak signals and minimize noise. The main goal of a low noise power amplifier is to provide high gain, low noise figure and good linearity performance, which can effectively amplify tiny input signals while minimizing the introduction of noise, which is essential for maintaining signal clarity, enhancing receiving sensitivity and improving the overall performance of the system.

[0035] Exemplarily, when the positioning system 1 is working, the RF front-end module 3 receives the satellite signal from the antenna module 2 and transmits the satellite signal to the first filter 31. The first filter 31 filters the satellite signal from the antenna module 2 to remove unnecessary frequency components or interference signals, retains the satellite signal of the specified frequency, and transmits the satellite signal filtered by the first filter 31 to the amplifier 32 through the output end of the first filter 31.

[0036] The amplifier 32 amplifies the satellite signal from the first filter 31, increases its power level, strengthens the satellite signal, makes it easier to be processed by downstream components, and transmits the satellite signal amplified by the amplifier 32 to the second filter 33 through the output end of the amplifier 32, wherein the amplification factor of the amplifier can be adjusted according to specific needs. The second filter 33 further filters and adjusts the characteristics of the satellite signal processed by the first filter 31 and the amplifier 32, which can further weaken noise, reduce interference or select satellite signals within a specific frequency range, and transmits the processed signal to the switching module 6 through the output end for subsequent processing or next operation.

[0037] The above scheme can perform initial filtering on the satellite signal from the antenna module 2 through the first filter 31 to remove unnecessary frequency components or interference signals; amplify the satellite signal after filtering by the first filter 31 through the amplifier 32 to increase its power level and strengthen the satellite signal; and further weaken the noise, reduce interference or select satellite signals within a specific frequency range through the second filter 33.

[0038] In some embodiments, see Figure 1 , Figure 1 The positioning system 1 also includes a power supply module 7 .

[0039] The power supply module 7 is connected to the switching module 6 and the amplifier 32 .

[0040] Exemplarily, the switching module 6 switches the signal from the input end to the corresponding output end according to a specific logic or condition, and may have multiple input and multiple output channels, which are switched by control signals or logic, and are powered by connection with the power supply module 7. In order to ensure normal operation and to amplify the input signal into the required output, the amplifier 32 is connected to the power supply module 7 to obtain the required power supply, so that the power supply module 7 can provide the required power supply voltage and current.

[0041] In some embodiments, see Figure 1 , Figure 1 : is a circuit schematic diagram of the positioning system of the present application. The first positioning module may be a GPS positioning module, and the second positioning module may be a Beidou positioning module. In other embodiments, the first positioning module may be a processor module, the processor module is integrated with a GPS positioning service, and the second positioning module may be a Beidou positioning module.

[0042] The GPS positioning module is a hardware device used to obtain the Global Positioning System (GPS) signal and accurately measure the location of the device. It is usually composed of a GPS receiver and related circuits. The GPS positioning module receives wireless signals from the satellite system, decodes and calculates the geographical coordinates of the device, where these coordinates usually include information such as longitude, latitude and altitude. The GPS positioning module can communicate with multiple satellites to obtain more accurate positioning information.

[0043] Beidou positioning module is a hardware device used to obtain signals from China's national satellite navigation system (Beidou NavigationSatellite System, referred to as Beidou system) and perform positioning. It is a global satellite navigation system independently developed by China, consisting of a group of satellites and ground control systems, providing global positioning and navigation services. Beidou positioning module is usually composed of Beidou receiver and related circuits, which can receive the navigation signal of Beidou system, decode and calculate, and obtain the longitude, latitude, altitude and other location information of the equipment. Beidou positioning module can be widely used in vehicle navigation, ship positioning, logistics tracking, agricultural monitoring, resource investigation and other fields, and compared with GPS positioning module, Beidou positioning module has better signal coverage and positioning accuracy in China. At the same time, Beidou system also supports international networking, and is gradually achieving global coverage, providing navigation and positioning services for international users.

[0044] Exemplarily, when the positioning system 1 is working, the switching module 6 receives the satellite signal after filtering and amplification by the RF front-end module 3. The satellite signal after filtering and amplification by the RF front-end module 3 is transmitted to the GPS positioning module connected to the first output port 62 through the transmission path between the input port 61 and the first output port 62. The GPS receiver built into the GPS positioning module receives the satellite signal after filtering and amplification by the RF front-end module 3, and decodes and processes the received satellite signal, wherein each satellite broadcasts navigation information at a specific frequency, including the location, time and other data of the satellite, and the GPS positioning module obtains the location and time data of each satellite by parsing this information, and calculates the location of the device using the triangulation principle. The GPS positioning module can determine the distance between the device and these satellites by receiving signals from multiple satellites at the same time, and the location information of each satellite is known information. By comparing the relationship between the distance between the device and these satellites and the location information of each satellite, the GPS positioning module can calculate the specific location of the device. The GPS positioning module uses the received satellite signals and location data to perform positioning calculations using algorithms. By incorporating the ranging information between the device and multiple satellites into the calculation, the positioning module can accurately calculate the device's longitude, latitude, altitude and other location information.

[0045] The satellite signal after filtering and amplification by the RF front-end module 3 is transmitted to the Beidou positioning module connected to the second output port 63 through the transmission path between the input port 61 and the second output port 63. The Beidou positioning module receives the satellite signal after filtering and amplification by the RF front-end module 3 through the built-in reception and demodulates the received signal to obtain the navigation message and carrier frequency and other information sent by the satellite, and selects at least 3 visible satellites for positioning calculation according to the received satellite navigation message. The Beidou positioning module calculates the distance between the receiver and each satellite by measuring the propagation time difference of the received satellite signal, wherein the ranging method may include pseudo-range measurement and carrier phase measurement. The Beidou positioning module can cross-position through the ranging values ​​of multiple satellites and accurately calculate the longitude and latitude coordinates of the receiver.

[0046] In the above scheme, the GPS positioning module and the Beidou positioning module can receive the satellite signals after filtering and amplification by the RF front-end module 3, and extract the navigation information in the satellite signals, and use algorithms such as triangulation to calculate the position coordinates of the receiver based on the navigation information in the received satellite signals and the distance and time difference between the satellite and the receiver.

In a specific implementation scenario, the electronic device 100 may include but is not limited to: a microcomputer, a server, and in addition, the electronic device 100 may also include a mobile device such as a laptop computer and a tablet computer, which is not limited here.

[0048] Specifically, the processor 102 is used to control itself and the memory 101. The processor 102 can also be called a CPU (Central Processing Unit). The processor 102 can be an integrated circuit chip with signal processing capabilities. The processor 102 can also be a general-purpose processor, a digital signal processor (Digital Signal Processor, DSP), an application-specific integrated circuit (Application Specific Integrated Circuit, ASIC), a field-programmable gate array (Field-Programmable Gate Array, FPGA) or other programmable logic devices, discrete gates or transistor logic devices, discrete hardware components.

[0049] In the above scheme, satellite signals can be received by the antenna module and sent to the RF front-end module. The RF front-end module is used to filter and amplify the new satellite signals. The satellite signals processed by the RF front-end module are then transmitted to the first positioning module or the second positioning module through the switching module for positioning processing to obtain relevant positioning information such as position and time.
