Abstract
The precision single point positioning technology is becoming more and more mature. Under the research and technical improvement of scholars at home and abroad, the precision of precise single point positioning has reached millimeter level, and has been well developed in daily production and application. In satellite signal positioning, tropospheric delay will affect the positioning accuracy. However, different correction models can be obtained according to different correction princip
