Design and Application of data real-time transmission system of GPS land survey device

Abstract

In order to ensure the high positioning precision of GPS land survey device and uploading the investigating data to data central real time, the paper analyses the advantages and disadvantages of several wireless communication technique in common use. And a data transmission system used in GPS land survey device is designed and developed based on GPRS. The results of lots of tests and applications show the feasibility and reliability of the data transmission system.
