Slant Delay / Multi Pass

Slant Tropospheric Delay based on Post-fit Residual, Multipassi Stacking Map

Slant Delay / Multi Pass

The sky maps above show stacked post-fit residual of phase for (left) GPS, (middle) GLONASS, and (right) QZSS. Similar feature of multipath reflected from nearby pole is reproduced in residual in multi GNSS.

 

Post-fit residual in multi GNSS processing

Slant Delay GPS< GLONASS< QZSS

RTNet can handle multiple GNSS satellite observations. Addition of GLONASS and QZSS in GNSS processing shows consistent residual with GPS-only processing in active weather conditions, suggesting that multiple GNSS residual can be handled with the same way with GPS.
