摘要

多天线GNSS广泛应用于各个行业，它由三个或多个L1 GPS接收机组成。该系统具有较高的相对坐标测定精度(厘米精度)。该系统的主要缺点是由于需要解决相位模糊问题，启动周期长。对其解析进行了分析，提出了缩短启动时间的方法。它包含了比例测试和搜索所有候选LAMBDA方法，具有优先级限制，减少了三倍的时间。

Algorithm of reducing the time of resolving phase ambiguities of multi-antenna global navigation satellite system by using priori information

Multi-antenna GNSS are widely used in various industries, it consists of three or more L1 GPS receivers. This system provides the high accuracy of relative coordinates determination (centimeter accuracy). The main drawback of this system is a long start period because of the need of resolving phase ambiguities. Analysis of the resolving was held and the method of reducing start time was proposed. It includes Ratio test and search of all candidates of LAMBDA method with a priory limitation and reduces the time the threefold.
