Abstract

The invention discloses a multi-frequency and multi-mode RTK positioning system, which relates to the field of satellite positioning systems, including a broadband antenna system, a pre-stage multi-mode and multi-frequency navigation radio frequency chip or a corresponding circuit, and multiple parallel-processed multi-mode and multi-frequency navigation baseband chips Or the corresponding circuit, the multi-mode multi-frequency navigation baseband chip or the corresponding circuit of the homogeneous parallel processing has the satellite navigation and positioning signal measurement synchronization function and the positioning calculation communication function, so the measured values ​​of each chip or circuit can be jointly solved. Calculate the position information, you can use the differential information to achieve high-precision real-time dynamic differential positioning. The multi-frequency and multi-mode RTK positioning system of the present invention uses multiple homogeneous and parallel-processed navigation and positioning chips to form a new implementation scheme to meet the synchronous large-scale measurement and processing conditions required by real-time dynamic positioning technology, thereby replacing the original expensive A single chip solution creates conditions for the popularization of applications.

Description

technical field [0001] The invention relates to the field of satellite navigation, in particular to a system for realizing multi-frequency high-precision real-time dynamic differential positioning technology by using signals of a satellite navigation and positioning system. Background technique [0002] The satellite navigation and positioning system can realize positioning at any place and at any time without occlusion. Satellite navigation and positioning systems include China's Beidou second-generation satellite navigation and positioning system, the United States' GPS global satellite navigation and positioning system, Russia's GLONASS satellite navigation and positioning system, the European Union's Galileo satellite navigation and positioning system, and other regional satellite navigation systems GPS. Among the four global navigation systems, each system has multiple frequency band signals for simultaneous reception. The most commonly used concentrated single frequen...
