Problems solved by technology

This method is suitable for applications where the GNSS antenna is easy to install and does not deform relative to the baseline to be measured, but in some applications where vibration, torsion and other carrier deformation occur, the position of the GNSS antenna changes with the The relationship between the measurement baselines is not fixed, resulting in the orientation result given by the satellite orientation system is not the real-time orientation of the baseline to be measured, thus limiting the application of the satellite orientation system in the deformation environment

Embodiment Construction

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0033] figure 1 It is a schematic diagram of the principle of using the optical imaging measurement system to correct the satellite baseline offset. The line AB is the baseline of the azimuth angle to be measured. In a non-deformable environment, the antenna is installed at points A and B. At this time, the baseline of the antenna coincides with t...

Abstract

The invention provides a virtual stable baseline satellite orientation method and device. The method includes the steps that amplifying, down-conversion and signal conditioning are conducted on satellite signals so as to convert the satellite signals into digital signals; capturing, tracking and demodulation are conducted on the digital signals, and the pseudorange, the carrier phase, the telegraph text and other original observation values of a satellite are obtained; positioning calculation and carrier phase solving ambiguity are conducted through the original observation value, and an orientation measurement value containing satellite antenna baseline deformation is calculated; the deformation quantity of a satellite antenna baseline is measured through an optical imaging system fixedly connected with an antenna; the satellite antenna baseline orientation result is amended through the deformation quantity, and the virtual stable baseline orientation result is obtained. According to the virtual stable baseline satellite orientation method and device, an optical imaging angle measuring system is additionally arranged on the basis of a satellite orientation system, possible displacement of the satellite antenna in a deformation environment is monitored, and stable baseline orientation output unrelated to the environment change is achieved.

Description

technical field [0001] The invention relates to the technical field of satellite orientation, in particular to a satellite orientation and data processing method and device under deformation conditions. Background technique [0002] Global Navigation Satellite System (GNSS), represented by GPS (Global Positioning System, Global Positioning System), can provide all-day, all-weather high-precision navigation, positioning and timing services. It has great benefits and is an important space and time infrastructure. my country's independent "Beidou-2" regional satellite navigation system has been put into operation at the end of 2012. The system provides services similar to the GPS system for my country and surrounding areas. It is planned to expand into a satellite navigation system with global coverage around 2020. [0003] Traditional satellite navigation receivers can calculate the three-dimensional position of the receiver antenna by measuring the distance between the recei...
