Development and experimental study of a network‐based RTK‐GPS positioning system using a satellite communication line

Abstract

SUMMARYThe geostationary satellite system will be able to disseminate data to a wider area and a greater number of users simultaneously. The authors tested the network-based RTK-GPS positioning using the area correction parameter (FKP) via the geostationary satellite-based communication line. They investigated network-based RTK-GPS positioning at several fixed points located inside the GPS reference station network area.

Initial performance evaluation of centimeter‐class augmentation system using Quasi‐Zenith Satellite System

“…Intervals of 5s and 30 s are defined for high‐speed and low‐speed correction, respectively; absolute value of each error is estimated in real time with regard to physical properties of range errors in satellite positioning. By using thus broadcast C‐SSR messages, users can realize network RTK‐GPS positioning; in so doing, there is no need for a base station required in case of conventional RTK positioning, or for individual means of correction data transfer, which promises more simple and convenient centimeter‐level real‐time positioning . The main performance parameters are time to first fix (TTTF): 1 min, root mean square error (RMSE): 3 cm horizontal, 6 cm vertical, for both fixed and moving targets.…”

GNSS augmentation through Ku-band communication satellites with RTK realization

“…A very small aperture terminal (VSAT) over a communication satellite is used to provide a data link between rover station and network-RTK control center in Japan [6]. However, the VSAT is costly and tedious to deploy and operate compared to satellite TV receivers.…”
