Problems solved by technology

Satellite and radio navigation are susceptible to interference due to man-made signals
Inertial navigation errors accumulate over time, making precise positioning difficult
The device cost of celestial navigation is high, and the calculation process is complicated
The patent number disclosed in the prior art: (CN 103115623A), the positioning technology with polarized light navigation technology as the core, cannot realize real-time positioning. This technical solution needs to measure the maximum polarization direction of the polarized light angle sensor at different times in order to calculate the latitude and longitude , at the same time implies a requirement that the position of the carrier cannot be changed in the two measurements before and after
This technology cannot provide real-time location information, and when the time interval is too short, the reliability and accuracy of the location information will be significantly reduced
The direction sensor, that is, the electronic compass, needs to be combined with the geographical location to obtain the magnetic declination data information in order to give the true north direction, but the patent number disclosed in the prior art: (CN103115623A) does not take this problem into account

Abstract

The invention discloses a positioning system based on a multi-directional polarized light navigation sensor. The positioning system comprises a fixed frame and an upper computer, wherein polarized light angle sensors for measuring the maximum polarization direction of incident light are installed on any two planes respectively, a level sensor and a direction sensor are installed on a datum plane of the fixed frame, and an astronomical calendar query module and a geomagnetic information query module are arranged in the upper computer. According to the system, a polarized light navigation technology and astronomical knowledge are combined, measured values of the level sensor, the polarized light angle sensor and the direction sensor on the fixed frame are obtained, geomagnetic declination data information is queried through the geomagnetic information query module in the upper computer, sun declination delta values at certain moments and true sun time differences on certain days are queried through the astronomical calendar query module, and the longitude and the latitude of a carrier are obtained through calculation by using an algorithm disclosed in the invention according to the data information.

Description

technical field [0001] The invention relates to a positioning system and a positioning method thereof, in particular to a positioning system based on a multi-directional polarized light navigation sensor and a positioning method thereof. Background technique [0002] The current positioning technology mainly includes satellite navigation, inertial navigation, astronomical navigation and radio navigation. Satellite and radio navigation are susceptible to interference due to man-made signals. Inertial navigation errors accumulate over time, making precise positioning difficult. The device cost of celestial navigation is high, and the calculation process is complicated. The patent number disclosed in the prior art: (CN 103115623A), the positioning technology with polarized light navigation technology as the core, cannot realize real-time positioning. This technical solution needs to measure the maximum polarization direction of the polarized light angle sensor at different ti...
