不利观测条件下BDS与GPS测量数据对比
|
摘要
某测区范围内山大沟深,植被茂密。首级平面控制测量时,选择兼容三星系统(BDS、GPS、GLONASS)的GNSS接收机进行了观测,数据处理采用支持三星系统的CGO软件。针对不利的观测条件(接收卫星数量少、持续跟踪锁定卫星能力差等)采用了较为先进的GNSS接收机进行观测,较为科学的软件进行解算,通过数据计算分析表明:不利观测条件下,BDS静态测量数据精度略优于GPS。
Dayugou Reservoir is located in Dagugou,Shang Town,Danfeng County. The measured area is deep and the vegetation is dense. When the first-level plane control network is established,three GNSS receivers of Samsung systems( BDS,GPS,GLONASS) are selected for observation,the Huace CGO software supporting Samsung's system was selected to analysis the data. In view of unfavorable observation conditions( small number of receiving satellites and poor ability to continuously track and lock satellites),more advanced GNSS receiver are used for observation,and more scientific software is used for calculation. According to the result of data calculation and analysis,it showed that under adverse observation conditions,the accuracy of static measurement data by BDS is slightly better than GPS.
