Quasi Zenith Satellite System (QZSS) is a Global Navigation Satellite System (GNSS) technology system belonging to the Japanese government, whose satellites have orbits and operate in Indonesian territory. Positioning activities using satellites from QZSS are carried out using the Real-Time Precise Point Positioning (RTPPP) method in absolute terms with orbit and clock errors correction obtained directly from the QZSS satellite. Currently, the Magellan System Japan (MSJ) receiver has the feature to be able to receive precise orbit and clock correction, and can perform heading determinations using the QZSS satellite. The purpose of this research is to test the accuracy performance of heading data which is estimated using precise clock and orbit correction from the satellite. To find out these problems, in this study, heading data acquisition was carried out using precise orbit and clock correction from QZSS using a static and kinematic MSJ receiver, then the acquisition data would be compared with the heading data obtained using several other heading data acquisition observation methods using RT- PPP RTX, static GNSS and Total Station. The results of the comparison of absolute static headings estimated using the correction from the QZSS satellite with static GNSS have a difference of up to 0.022º, the comparison with the total station has a difference of up to 0.285º, while for comparison with RT-PPP RTX has a difference of about 0.18º. Comparison of kinematic heading data using corrections from the QZSS satellite with static GNSS, has a difference of up to 0.524º and for comparison with RTPPP RTX kinematics, has a difference of up to 0.21º. Based on these results, it can be concluded that the level of precision and accuracy of the heading data estimated using corrections from the QZSS satellite acquired using the MSJ receiver will adjust to the acquisition method used, as well as reviewing the error and measurement conditions in the comparison method used. In the static position, the level of precision and accuracy produced has a better value when compared to the kinematic position, in terms of the standard deviation value and the difference in the value of the comparison.
