摘要
Abstract
GPS signal undergoes an additional time delay due to the index of refraction. The time delay produced by the troposphere increases with decreasing elevation angle and approaches a value corresponding to a range error of about 25 m for an elevation angle of 5 degree. The characteristics and error correction model of troposphere delay are systematically investigated. At the same time, a simple troposphere delay model is proposed based on Saastamoinen model. Simulation results indicate that this simply model can effectively eliminate troposphere delay and improve GPS positioning accuracy without the actual measured meteorological parameters.关键词
