Open publisher page 0 citations

Abstract

The e-VLBI technique inherits the high angular resolution from the traditional VLBI technique,and the results from e-VLBI observation can be obtained quickly with high speed communication network to transmit its data.These advantages are quite beneficial to the rapid determination of satellite orbit and the improvement of existing accuracy of orbit determination.By analyzing the technical characteristic of e-VLBI,reviewing it′s development,and combining with the differential VLBI measurement of satellite,we mainly discuss the current application situation,development obstacles and requirements for the e-VLBI technology in China,and the prospect of e-VLBI in China is also discussed.
