the latest version of the open-source software PRIDE PPP-AR version 2.2. Based on the feedback of
global users in the past two years, we have been improving the software to
enhance its robustness and make it easy to use. Now v2.2 fully supports GPS/GLONASS/Galileo/BDS-2/3/QZSS
PPP and undifferenced ambiguity resolution for GPS/Galileo/BDS-2/3. Its
high-precision GNSS data processing capabilities are improved, especially in
that it supports kinematic positioning for mobile platforms such as aerial
photogrammetry and ship-borne gravimetry; high-rate data up to 50Hz can also be
processed; the second-order ionospheric delays can be corrected; VMF3 for
troposphere modeling is available; multi-day processing is allowed; satellite
attitude quaternions are supported as well; and many more. Besides the Linux
version, we also provide a Windows and a Mac OS version to facilitate early
researchers and class teaching.</span></p>
