New Version of PPP-Wizard Demonstration Software Published

October 9, 2014 - By GPS World Staff

A new version of the open source PPP-Wizard user software has been published. The link to download the wizard is being provided on request, so the International GNSS Service (IGS) can keep track of interested users.

The PPP-Wizard is defined as a precise point positioning with integer and zero-difference ambiguity resolution demonstrator. Available for non-commercial purposes, it performs real-time PPP using corrections streams provided by the IGS Real Time Service. It features:

GPS and GLONASS code and phase measurements (mono or dual frequency)
Ambiguity resolution on GPS thanks to the new standardized phase biases messages (with the compatible CLK91 stream)
Advanced RAIM
SBAS iono for single-frequency receivers (u-blox and nvs receivers)
Fast reconvergence using iono estimation
Compatibility with rtklib and BNC (rtrover interface)
Multiple receivers processing
Preparation for augmented regional networks (tropo & iono interface)
C/C++ portable and light implementation

The PPP-Wizard demonstrator is a “proof of concept” of the zero-difference ambiguity resolution method developed in the orbit determination service at CNES.
