PPPAR

Files for GNSS precise point positioning (PPP) with ambiguity resolution

Goal

GNSS PPP with ambiguity resolution

• Support ionospheric-free combinations and uncombined/raw models
• Support multiple carrier frequency signals
• Support multiple GNSS systems
• Support real-time applications

Status

GPS/Galileo/BDS ionospheric-free PPP with ambiguity resolution

• phase bias product
• open source software (Under internal testing and will be availablle at this repository)
