ABSTRACT
work RTK technique is a new style of has been wildly used in many areas depending on its eximious performance,wel l stabi l ity and credible is epoch-making in the history of GPS position
technique。Troposphere delay errors i s one of the most primary errors in work RTK technique ,it must be el iminated or weakened. Basing on the introduction of troposphere ponents and refraction principle in detai l,This paper plot the work RTK
technique out two parts and discuss their troposphere correcting models and methods respectively,according to its technique character..
For the troposphere delay models on datum station,the writer discuss it on zenith delay models,zenith delay parameter estimating methods and mapping function,and do much experiments wi th the supposed work. 1、 Fixing on the number of zenith delay parameter is much more important
to simulate the ic wave refracting path through the troposphere。The writer believe that troposphere parameter number should be adopted 1 per 2---4 hours(namely 7"--,13/day)paring
the results precision on troposphere models with different parameter
.number.
2、The writer analyze the single parameter estimating methods,mulriple parameter estimating methods and subsection linear random process method,and discuss puting results paring the precision。Though analyzing,the writer think that subsection linear random process method i s more perfect.
