The number of the satellite which can be used for the positioning increases when GPS was developed by America and GLONASS by Russia are received at the same time. Therefore, the improvement of the positioning accuracy and availability are being expected. The research result of GPS/GLONASS by the point positioning and the differential positioning are reported until now. However, there is few that of the kinematic positioning by the onboard. Accordingly, the authors carried out the experiment of the kinematic positioning by a ship and a car using the equipment which can receive the GPS satellite and the GLONASS at the same time. Then we analyzed the effectiveness of the kinematic GPS/GLONASS. As a result, there was little effectiveness by using GLONASS in common, as there was nothing to cover the radio wave of the satellite on the sea area. However, in the land area with a large number of buildings, the time when the positioning was impossible decreased by increase of satellites. In addition, there sometimes had an effect on the positioning accuracy because of the satellite allocation of GLONASS. Therefore, it came to the conclusion that there was a large effectiveness by using GLONASS in common.
