Abstract:	We proposed an RTK-GPS protocol, named SNUR-2000 v. 2.2 to RTCM SC-104 3.0 working group. The SNUR- 2000 v. 2.2 has two types of messages; pseudorange corrections and carrier phase corrections. Using these messages, we can carry out precise positioning without accuracy degradation; latency effect is negligible when RTK corrections are broadcast by low-rate data-link whose baud rate is as low as 500bps. In this paper, we show test results of RTK-GPS whose corrections are transmitted to RTK user via 500bps data-link. Test results demonstrate that the latency effect on the accuracy of RTK-GPS with 500bps data-link is negligible.
