摘要
在精密GPS测量中,大气折射改正误差是主要误差源之一。基于大气折射理论,把底层大气分为7层,并考虑不同高度的重力改正,建立了新的大气层模型,推导出了新的更精确的折射改正公式。实例计算结果表明,新的大气层模型更加符合实际。
he error of correction for atmospheric refraction is one of the maim error sources in precise GPS measurement.Acording to the atmospheric refraction theory,dividing the bottom atmosphere into seven layers and considering the gravity correction in different elevation, a new atmospheric model is built and a more precise correction formula for the refraction is obtained.the results computed show that the new atmospheric model corresponds further to practical situation.
