Embodiment Construction

[0028] In order to better understand the technical solutions of the present invention, the embodiments provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0029] The embodiment of the present invention provides a multi-mode embedded integrated navigation receiver, which is used to receive multi-system navigation satellite signals, and perform corresponding processing to realize precise positioning, and provide the position information of the multi-mode embedded navigation receiver, which is widely used Used in military and civilian occasions. The navigation receiver is multi-mode embedded and adopts a "two-chip" structure, which includes a radio frequency receiving chip (RFIC) and a baseband processing chip (FPGA). The design structure of "two-chip computer" guarantees the industrialization, scalability, continuity and reconfigurability of the multi-mode embedded integrated navigation receiver to the greatest ext...

Abstract

The invention provides a multi-module embedded combined navigation receiver which comprises a radiofrequency receiving chip and a baseband processer chip, wherein the baseband processer chip comprises a multi-module radiofrequency data processing unit, a capture unit, a tracing unit and a premise point positioning and processing unit. The multi-module embedded combined navigation receiver does not need a digital signal processor (DSP), and the positioning is realized only by combining the baseband processer chip with software; thus, the navigation receiver has the advantages of simple structure, less cost and high reliability.

Description

technical field [0001] The invention relates to the field of navigation equipment, in particular to a multi-mode embedded integrated navigation receiver and a positioning method. Background technique [0002] Around 2010, my country will build a regional satellite navigation system "Beidou II" that can expand to the world, realizing real-time three-dimensional positioning, speed measurement, high-precision timing, and user location reporting and two-way reporting covering my country and surrounding areas and sea areas. text communication. At that time, my country's satellite navigation and positioning users at all levels will face the situation that four global satellite navigation systems can be used at the same time. These systems are the US Global Positioning System (GPS), Russia's GLONASS; The "Beidou II" system is under construction. [0003] With the development of satellite technology and the surge of GPS user demands, the US GPS Collaborative Committee has made short...
