Abstract

The invention discloses a multi-frequency multi-mode satellite positioning communication device and a hybrid positioning information control method, and belongs to the field of satellite navigation. The device comprises an antenna unit and a positioning communication unit which are connected with each other; the antenna unit comprises a first combiner, a first channel selector, n first power amplifiers, n first filter circuits, an antenna, n second filter circuits, n first amplification filter circuits, a first power division combiner and a first cable interface; the positioning communication unit comprises a second cable interface, a second channel selector, a second power division combiner, n third filter circuits, a third channel selector, a radio frequency chip, a baseband chip and n fourth filter circuits. According to the device, a multi-frequency multi-mode positioning communication mode is used, the dependence on single-satellite, double-satellite or three-satellite systems is reduced, and the working efficiency of system communication is improved.

Description

technical field [0001] The invention relates to the field of satellite navigation, in particular to a multi-frequency and multi-mode satellite positioning communication device and a hybrid positioning information control method. Background technique [0002] In order to reduce the design difficulty of existing positioning communication systems, most of the positioning and communication functions work independently or in single-frequency positioning or dual-frequency multi-mode positioning mode. The system positioning mode and communication mode are very simple. Therefore, the existing positioning communication system is highly dependent on single, double or triple satellite systems, and the existing satellite positioning communication system has few communication frequency points and low efficiency. Contents of the invention [0003] The purpose of the invention is to use the multi-frequency and multi-mode positioning communication mode, reduce the dependence on single, do...
