一种北斗无高程RDSS定位模型及其误差分析
A BEIDOU RDSS POSITIONING MODEL AND ITS ERROR ANALYSIS WITHOUT ELEVATION
摘要
Abstract
The location reporting service provided by RDSS of Beidou navigation satellite system allows users to inform the outside world of their positions, and it has been widely used in water conservancy, marine, marine fisheries, forest fire prevention, disaster relief and other fields.Beidou RDSS positioning requires high-precision elevation data of users.However, the high-precision elevation data is difficult to acquire in remote regions and areas outside mainland China.To solve this problem, an RDSS positioning model without elevation is designed.When more than two RDSS satellites are observed, the redundant observation satellites are used to carry out positioning, instead of elevation, and the positioning error in this model is analyzed.Simulation experiment indicates that the DOP value and positioning error of RDSS positioning without elevation are much larger.Under the same pseudo-range error, the positioning error increases exponentially with the user position latitude increasing.The longitude error in positioning results is far less than the errors in latitude and elevation.关键词
