great_pvtflt provides a filter-based realtime high-precision GNSS solution, which supports both standalone PPP and short/long-baseline RTK/PPK.

Capable to process multi-GNSS data(GPS, GLONASS, Galileo, BDS, QZSS, etc.) in multi-frequency.

Ionospheric-free and undifferenced-and-uncombined observation models are supported.

In RTK/PPK mode(or in PPP-AR mode given specific products), ambiguity-fixed solutions can be achieved.

Here are some results.

Example 1,which is the result of static PPP,using the data collected in Wuhan on 2019/9/17

Example 2,which is the result of dynamic PPP,using the data collected in the suburbs of Wuhan on 2019/9/18

Example 3,which is the result of RTK fixed,using the data collected in the suburbs of Wuhan on 2019/9/18
