Embodiment Construction

[0071] now attached Figures 1 to 3 The present invention is described in further detail.

[0072] The multi-antenna attitude measurement method based on the Beidou system first needs a receiver hardware platform that can support Beidou multi-frequency point signal reception, see figure 1 .

[0073] The present invention is realized in figure 1 The data processing module is usually an embedded platform. The embedded platform realized by the present invention is DSP. The three zero-phase center antennas of the Beidou receiver receive satellite signals, and after filtering, amplifying and combining in the antennas, the satellite signals are respectively transmitted to the radio frequency unit of the host. The radio frequency unit amplifies, filters, and down-converts satellite signals to output intermediate frequency signals; the baseband processing unit digitally samples each intermediate frequency signal, and captures, tracks, and demodulates and analyzes satellite signals...

Abstract

The invention provides a multi-antenna attitude determining method based on a Beidou system. With the establishment and improvement of the Beidou satellite regional navigation system, the use of the Beidou satellite system for high-precision attitude determination has become one of the hot spots in the field of navigation. The method is based on the realization of the Beidou receiver hardware embedded platform and based on the three-antenna carrier phase data simultaneously observed by the Beidou receiver, the double-difference model is constructed and finally the high-precision attitude information is obtained. The present invention mainly makes innovation and improvement of the satellite selection strategy, the cycle slip detection method, the rough error rejecting and fuzziness calculation method, the base line verification method in the attitude determination flow. The method is highly modularized, supports various platforms, is particularly suitable for the embedded receiver platform, and has a wide application prospect.

Description

technical field [0001] The invention relates to the field of satellite navigation, in particular to a method for autonomously realizing carrier attitude measurement based on the Beidou system without the assistance of an external augmentation system. Background technique [0002] With the establishment and improvement of my country's Beidou satellite regional navigation system, the use of Beidou satellite system for high-precision attitude measurement has become one of the research hotspots in the field of navigation. Compared with traditional optical and infrared attitude measurement, or attitude acquisition technologies such as inertial navigation and sensors, the use of Beidou attitude measurement has the advantages of high precision, low cost, and the accuracy will not weaken over time. In addition, it is not controlled by others during wartime. Therefore, the use of Beidou for attitude measurement has great application potential, and it is of great significance to inven...
