摘要

为验证北斗双星定向中所提出的通过延长基线确定模糊度的方法

利用双天线北斗载波相位接收机系统构建了实验平台

设计了延长基线北斗定向物理实验方案

通过事先在实验场地确定同一方向不同基线长度的若干天线放置位置实现了该方案。实验结果表明

用延长基线法确定北斗定向载波相位单差模糊度是可行的

在延长基线期间无周跳发生时成功率可达100%。此外

辅助验证了影响北斗定向精度的若干确定性影响因素

包括基线长度、定向时长以及基线指向等

提出为提高定向精度

应适当增加基线长度

延长定向时间

并尽可能令基线指向接近南北方向。该项研究将进一步促进北斗定向技术的实际工程应用。

Abstract

To verify the feasibility of an ambiguity resolution method for Beidou bi-satellite orientation by extending baseline

an experimental platform was established by using a Beidou carrier phase receiver with two-antennas. A physical experiment scheme was proposed for the extending baseline

which was realized by determining different positions of several antennae with different baseline lengths in the same direction in advance. The results show that it is feasible to determine the ambiguity of a Beidou single difference carrier phase by extending baseline

and the success rate can reach 100% without cycle slips during extending baseline. Moreover

some deterministic factors such as baseline length

orientation duration

and baseline direction on Beidou orientation were verified by the way. It suggests that the baseline length and orientation duration should be prolonged

and the baseline direction should be as near south-north as possible in order to improve the orientation precision. The research work will greatly improve the practical engineering application of Beidou orientation technology.
