Processing and Solutions

Station used for test processing where baseline length is a few meters.

Coordinate Estimate
Coordinate solutions for GPS only (red) and GPS+QZSS (green) baseline processing. This is preliminary solution with the first stage dataset after QZSS launch. Processing with newer data and consistent QZSS antenna model is recommended. Now user can use precise ephemeris from JAXA, and template input file with precise orbit file is available (PP_PPP_KIN_GFRFQF_L3_GGQ)
