Features of PRIDE PPP-AR ver. 3.0

1) Multi-GNSS data processing with GPS, GLONASS, Galileo, BDS-2/3 and QZSS;

2) All-frequency PPP-AR on any dual-frequency ionosphere-free combinations of GPS, Galileo, and BDS-2/3;

3) High-rate GNSS data processing up to 50 Hz;

4) High-dynamic mobile platforms applicable for aerial photogrammetry, ship-borne gravimetry, etc;

5) Kinematic orbiting for LEO satellites;

6) Multi-day processing up to 108 days without day-boundary discontinuities;

7) IPPP clock estimation for time and frequency transfer;

8) Troposphere modeling with Vienna Mapping Function 1/3 (VMF1/VMF3);

9) Second-order ionospheric delay correction with GIM products;

10) Receiver clock jump detection and mitigation;

11) Adoption of the latest IGS conventions: Bias-SINEX, IGS20 reference frame, ORBEX, RINEX 4, etc.;

12) User-friendly operation and visualization for early-career researchers with lite-version GUI;

13) Ambiguity-float PPP with backward compatibility from 1994 when selective availablity (SA) was on;

14) Timely data processing with rapid (RAP) products and real-time archived (RTS) products.

15) Use oceanload correction module supported by Chinese Academy of Surveying and Mapping to enable oceanload correction without oceanload coefficient.
16) Determine whether cross-day ambiguities need to be truncated according to the bias-SINEX file DOCB data block.
17) Support epoch-by-epoch position constraint function (P mode)

Improvements made in PRIDE PPP-AR version 3.0

1) Enable all-frequency PPP-AR on any dual-frequency ionosphere-free combinations;

2) Employ the latest WUM0MGXRAP products to resolve ambiguities on new GNSS signals (L5/E6/E5b/E5B/B1C/B2a/B2);

3) Support kinematic orbiting for LEO satellites;

4) Improve capability and long-term consistency of multi-day processing;

5) Provide more command-line options and models for parameter estimation;

6) Increase compatibility with the latest IGS data and product extensions;

7) Refine the data format of result files and the output information of program runs.

Notes: The all-frequency satellite orbit/clock/bias/ERP/quaternion products from Wuhan University are required by PRIDE PPP-AR.

8) Add oceanload correction module supported by Chinese Academy of Surveying and Mapping to enable oceanload correction without oceanload coefficient.
9) Employ the bias-SINEX file DOCB data block to determine whether cross-day ambiguities need to be truncated.
10) Support epoch-by-epoch position constraint function (P mode).
