Firstly, thebasic principle on RS surveying isbriefly introduced, then the key technologies of RS such as error analysisambiguity solutioncom- putation correction and so on are specified. Finally, mathematics models are deducted based on NetRTK by means of differential technology bewt een satellites and between receivers, so that itmay provide references for RS researches.
