基于高动态场景下的GNSS接收机定位性能评估
Performance evaluation of GNSS receiver positioning based on high dynamic scenarios
摘要
Abstract
With the vigorous development of China's Beidou-3 and GNSS global navigation systems,spaceborne GNSS receivers have become one of the standard payloads on low Earth orbit satellite platforms.Traditional application scenarios are usually in ground terminals and monitoring stations.This article uses pseudo-range and phase data from spaceborne GNSS platforms to study positioning algorithms and evaluate positioning performance.The positioning algorithm implementation and accuracy evaluation are carried out using data from high dynamic scenes of spaceborne GNSS platforms.The positioning performance is analyzed using dual frequency GPS receivers mounted on GRACE-FO and Jason-3 satellites with an orbit altitude of 500 km.The actual measurement results show that the phase floating point solution using dual frequency ionosphere free combination has a comparable accuracy of 4 cm compared to official precision products,with GRACE-FO phase positioning accuracy of 3.3 cm and Jason-3 phase positioning accuracy of 3.5 cm.关键词
