The transmitter 1022 may include a baseband chip and a radio frequency modem, and the transmitter 1022 may be a TDD transmitter or an FDD transmitter according to the communication mode of the vehicle-mounted device 100. For example, the transmitter 1022 may be a radio frequency chip in the in-vehicle device 100, or a cellular module.

In a possible embodiment, the vehicle-mounted device 100 further comprises a filter 106, and the filter 106 is respectively connected to the receiving antenna 104 and the switch device 103, as shown in fig. 8a, or the filter 106 is respectively connected to the switch device 103 and the navigation positioning information receiver 105, as shown in fig. 8 b. The filter 106 is configured to filter an interference signal in the target signal, where the interference signal is a signal whose frequency is outside a frequency band where the target signal is located, so as to further improve the quality of the target signal.

The filter 106 is a band-pass filter, which filters out signals with frequencies outside a frequency band of the target signal, and may be a hardware filter or a software filter, for example, the filter 106 may be a Surface Acoustic Wave (SAW) filter.

In one possible embodiment, the in-vehicle apparatus includes: a processor 101, a receiving antenna 104, a navigation positioning information receiver 105 and an uplink signal transmitting device 102. The processor 101 is respectively connected to the navigation positioning information receiver 105 and the uplink signal transmitting device 102, and the navigation positioning information receiver 105 is further connected to the receiving antenna 102, as shown in fig. 9. Wherein the content of the first and second substances,

the processor 101 is configured to control the navigation positioning information receiver 105 not to process a target signal carrying navigation positioning information before the uplink signal transmitting device 102 transmits an uplink signal; and when the uplink signal transmitting device does not transmit an uplink signal, controlling the navigation positioning information receiver 105 to acquire navigation positioning information in the target signal; the receiving antenna 104 is configured to receive the target signal; the navigation positioning information receiver 105 is configured to process the target signal under the control of the processor 101.

In this embodiment, before the uplink signal transmitting device 102 in the vehicle-mounted device 100 transmits the uplink signal, the processor 101 in the vehicle-mounted device 100 controls the switch device 103 to turn off the path between the receiving antenna 104 and the navigation positioning information receiver 105, so that the navigation positioning information receiver 105 cannot acquire the target signal received by the receiving antenna 104, when the uplink signal transmitting device 102 does not transmit the uplink signal, the processor 101 controls the switch device 103 to turn on the path between the receiving antenna 104 and the navigation positioning information receiver 105, so that the navigation positioning information receiver 105 can acquire the target signal received by the receiving antenna 104, process the target signal, and acquire the navigation positioning information in the target signal, that is, the vehicle-mounted device 100 acquires and processes the target signal carrying the navigation positioning information when it does not transmit the uplink signal, the influence of the uplink signal sent by the vehicle-mounted device 100 on the performance of the navigation positioning information receiver can be avoided, and the accuracy of navigation positioning can be further improved. For example, for TDD vehicle devices, each bit is as long as milliseconds (e.g., 20ms for civil GPS signal per bit time) due to the low rate of the target signal, while the duration of the uplink signal in a single slot of TDD vehicle device is microseconds (e.g., 677us for GSM single slot time). Therefore, even if the target signal is temporarily interrupted during the time when the TDD in-vehicle device transmits the uplink signal, the target signal reception is not affected.

Moreover, the vehicle-mounted device 100 has a low requirement on the isolation of the receiving antenna 104 and the uplink signal transmitting antenna in the vehicle-mounted device, so that the product design constraint on the vehicle-mounted device 100 can be reduced and the size of the vehicle-mounted device 100 can be reduced.

For example, the isolation between the navigation and positioning information receiver in the vehicle-mounted device and the transmitting antenna in the vehicle-mounted device is 10dB, the carrier to noise ratio (CNR) of the GPS signal transmitted by the satellite received by the navigation and positioning information receiver 105 in the vehicle-mounted device is 41dBHz in a scenario where the vehicle-mounted device 100 does not transmit the uplink signal, as shown in fig. 10a, the carrier to noise ratio of the GPS signal transmitted by the satellite received by the navigation and positioning information receiver in the vehicle-mounted device is 18dBHz to 20dBHz in a scenario where the vehicle-mounted device transmits the uplink signal but does not control the navigation and positioning information receiver in the vehicle-mounted device, as shown in fig. 10b, the carrier to noise ratio of the GPS signal transmitted by the satellite received by the navigation and positioning information receiver in the vehicle-mounted device is 18dBHz to 20dBHz in a scenario where the vehicle-mounted device transmits the uplink signal but the navigation and positioning information receiver is controlled by the switch device in the vehicle-mounted device As shown in fig. 10c, 38dBHz allows the carrier-to-noise ratio of the signal received by the navigation and positioning information receiver in the in-vehicle device to be significantly improved by controlling the navigation and positioning information receiver by the switching device in the in-vehicle device, where the horizontal axis in fig. 10a to 10c represents the satellite (satellite number) transmitting the GPS signal, and the vertical axis represents the carrier-to-noise ratio of the GPS signal received by the navigation and positioning information receiver.

In a specific embodiment, as shown in fig. 11, the vehicle-mounted device 100 includes the processor 101, the switch device 103, the receiving antenna 104, the navigation and positioning information receiver 105, the transmitting antenna 1021, the transmitter 1022, the filter 106, a memory 107, a communication interface 108, a power supply 109, and the like.

The communication interface 108 is used for connecting a vehicle computer 200 on a vehicle, so that a user can control and use the vehicle-mounted device 100 through a display unit 201 and an input unit 202 of the vehicle computer 200, the display unit 201 is a display system of the vehicle computer 200 and is used for presenting an interface and realizing man-machine interaction, and the input unit 202 can be used for receiving numerical or character information input by the user and generating key signal input related to user setting and function control of the vehicle computer 200. The display unit 201 may be a Liquid Crystal Display (LCD) or an organic light-emitting diode (OLED), and the input device unit 202 includes, but is not limited to, one or more of a touch screen, a physical keyboard, a mouse, and a joystick.

When a user inputs a phone number into the input unit 202 of the computer 200, the processor 101 of the vehicle-mounted device 100 determines that the transmitter 1022 needs to transmit an uplink signal, and controls the switch device 103 to disconnect the path between the receiving antenna 104 and the navigation and positioning information receiver 105 before the transmitter 1022 transmits the uplink signal, where the navigation and positioning information receiver 105 cannot receive a target signal carrying navigation and positioning information received by the receiving antenna 104.

When the processor 101 of the vehicle-mounted device 100 determines that the sending of the uplink signal for carrying one data packet corresponding to the current call is completed, that is, when the current call is completed, i.e., a gap between two adjacent uplink signals corresponding to the current call of the user and a function key for ending the call in the input unit 202 of the mobile computer 200 are used by the user, the processor 101 of the vehicle-mounted device 100 controls the switch device 103 to turn on a path between the receiving antenna 104 and the navigation positioning information receiver 105, and the navigation positioning information receiver 105 receives a target signal received by the receiving antenna 104 to acquire navigation positioning information in the target signal.

The navigation positioning information receiver 1203 is configured to receive a target signal sent by the receiving antenna 1201 when a path between the receiving antenna 1201 and the navigation positioning information receiver 1203 is turned on, and acquire navigation positioning information in the target signal.

When the switch device 1202 is an LNA, a controllable single-pole single-throw switch, or a controllable single-pole double-throw switch, the specific working principle thereof can be referred to the related description of the switch device 103 in the vehicle-mounted device 100, and details thereof are not repeated here.

In this embodiment, before the communication device where the navigation positioning information receiving apparatus 1200 is located sends an uplink signal, the switch device 1202 in the navigation positioning information receiving apparatus 1200 turns off the path between the receiving antenna 1201 and the navigation positioning information receiver 1203, so that the navigation positioning information receiver 1103 cannot acquire the target signal received by the receiving antenna 1101 in the navigation positioning information receiving apparatus, and when the communication device where the navigation positioning information receiving apparatus 1200 is located does not send an uplink signal, the switch device 1202 turns on the path between the receiving antenna 1201 and the navigation positioning information receiver 1203, so that the navigation positioning information receiver 1203 can acquire the target signal received by the receiving antenna 1201, process (e.g. demodulate) the target signal, and obtain the navigation positioning information in the target signal, that is, the navigation and positioning information receiving apparatus 1200 obtains and processes the target signal carrying the navigation and positioning information when the communication device where the navigation and positioning information receiving apparatus 1200 is located does not send the uplink signal, so that the influence of the uplink signal sent by the communication device where the navigation and positioning information receiving apparatus 1200 is located on the navigation and positioning information receiving apparatus 1200 can be avoided, the performance of the navigation and positioning information receiving apparatus 1200 is improved, and the accuracy of navigation and positioning can be further improved. For example, for the TDD communication device, since the target signal has a low rate, each bit has a duration of milliseconds, and the duration of the uplink signal in a single timeslot of the TDD communication device is microseconds, even if the target signal is temporarily interrupted during the time that the TDD communication device transmits the uplink signal, the target signal reception is not affected.

Moreover, the navigation and positioning information receiving apparatus 1200 has a low requirement for isolation between the receiving antenna 1201 of the navigation and positioning information receiving apparatus 1200 and the radio frequency signal transmitting antenna of the communication device in which the navigation and positioning information receiving apparatus 1200 is located, and the volume of the communication device in which the navigation and positioning information receiving apparatus 1200 is located can be reduced.
