Over time period, Global Navigation Satellite System (GNSS) technology presents many positioning services for engineering purposes or sciencetific purposes which provides from local to global area. Quasi-Zenith Satellite System (QZSS) is one of GNSS techonology owned by the Japanese Government which has orbit around the East Asia, Asia Pacific, and Oceania regions. Positioning with QZSS is determined with absolute positioning called Real-Time Precise Point Positioning (RTPPP) method, which utilized correction of time and orbit directly from the satellite and use Magellan System Japan (MSJ) receiver to do the acquisition. Therefore, QZSS will get a coordinate in a real-time condition and Root Mean Square Error (RMSE) which is a represention of accuracy. QZSS orbit through Indonesa region, so this research intend to look after the performance of QZSS in land territory of Indonesia. This research use primary data from acquisiton in PT Geotronix Indonesia, benchmark point at ITB Jatinangor, and along the Purbaleunyi toll road. Those data will processed to see the performance and compared with data from other GNSS receiver. On the result, QZSS with MSJ receiver is less consistent than other GNSS receiver in terms of stability. However, RMSE of QZSS resulting from acqusition in static condition is below 10 cm for horizontal position and below 15 cm for vertical position, at the same time RMSE of QZSS resulting from acqusition in kinematic condition is below 2 meter for horizontal position and below 4 meter for vertical position. Based on these results, QZSS with MSJ receiver need more development in order to maximum use.
