Embodiment Construction

[0020] The embodiments will be described in detail below in conjunction with the accompanying drawings.

[0021] The invention proposes a half-duplex pseudo-satellite device based on the Beidou RD function and a working method thereof. The working link of the pseudolite device of the present invention is as figure 1 shown. device such as figure 2 As shown, it includes: antenna unit, radio frequency unit, baseband unit, control processing unit, RD processing transceiver unit, power supply unit, internal clock, external clock interface and various interfaces for external data transmission. The antenna unit receives different navigation information through different antennas, and controls two different antennas to receive and broadcast through the antenna controller. The RF unit and the baseband unit mainly complete the processing and analysis of the signal. When the device is in different working states, the analysis methods are also different. As the brain of the pseudolit...

Abstract

The present invention belongs to the technical field of satellite navigation, and especially relates to a half-duplex pseudo satellite device based on a BeidouRD function and an operating method thereof. The half-duplex pseudo satellite device comprises an antenna unit, an RF unit, a baseband unit, a control processing unit, an RD processing and transceiving unit, a power supply unit, an internal clock, an external clock interface, and various interfaces achieving external data transmission; wherein the antenna unit is connected with the RF unit, the RF unit is connected with the baseband unit, the control processing unit is connected with the antenna unit, the RF unit, the baseband unit and the RD processing and transceiving unit, the power supply unit provides power for all parts in the half-duplex pseudo satellite device, the internal clock respectively provides clock for the control processing unit and the baseband unit, the external clock interface is connected with the RF unit and the baseband unit. The operating method of the half-duplex pseudo satellite devicecomprises three operating states, i.e., a pseudo satellite operating state, a forwarding operating state, and a monitoring state.

Description

technical field [0001] The invention belongs to the technical field of satellite navigation, and in particular relates to a half-duplex pseudo-satellite device based on the Beidou RD function and a working method thereof. Background technique [0002] As an important supplement to the satellite navigation system, the pseudolite significantly enhances the geometric structure of satellite positioning and improves the availability, stability and reliability of the satellite navigation system. Compared with the high manufacturing and use costs of satellite navigation systems, the advantages of low cost and convenient maintenance make pseudolites become the main technical means to enhance or even replace satellite navigation systems. At present, my country's Beidou satellite navigation system is in the stage of supplementing stars. Users will inevitably encounter interference and poor constellation distribution during use, which will have a great impact on the stability and relia...
