Problems solved by technology

In the prior art, Kechine et al. (2004) used small boats to test GNSS dynamic positioning and assumed that the trajectory of the boat was a straight line. The problem faced by this method is that the accuracy of the reference trajectory established is not high, and the dynamic test platform is in a specific The position at the moment is unknown, so the error of GNSS dynamic positioning in the orbit direction cannot be evaluated

Abstract

The invention relates to a dynamic positioning error test device, system and method for a navigation and positioning system. The test device comprises a circular track device, a measurement device anda test sensor. The measuring device and the test sensor are both mounted on the circular track device, and makes circular motion. According to the test device, system and method, the precision of thedynamic navigation system in the sub-millimeter level precision can be tested; and compared with a method in the prior art, the cost is lower, and the method, system and device can be used to evaluate different types of positioning technologies including absolute positioning and relative positioning technologies.

Description

technical field [0001] The invention relates to the field of geographic information, in particular to the field of positioning error testing of navigation and positioning technology, and specifically refers to a dynamic positioning error testing device, system and method for a navigation and positioning system. Background technique [0002] With the development of science and technology, the application range of navigation and positioning systems is becoming wider and wider, and the outside world also puts forward new requirements for the positioning error of navigation and positioning systems. [0003] The Global Navigation Satellite System (GNSS) is a commonly used navigation and positioning system that has been widely used in high-precision positioning applications, where the accuracy assessment of static GNSS positioning systems can be done with a known baseline (Lau et al., 2015, Quan et al. , 2016), the accuracy evaluation of the dynamic GNSS positioning system can be ...
