The versatile GNSS positioning software

Capabilities

Everything you need for precise GNSS processing

PPPx pairs a fast C++ core with the flexibility researchers and engineers need across constellations, frequencies and estimators.

SPP, PPP, RTK and TDP in one tool.

GPS, GLONASS, Galileo, BeiDou, and QZSS.

Choose Least Squares (LSQ), Extended Kalman Filter (EKF), or Factor Graph Optimization (FGO).

Runs on Linux, macOS and Windows.

See it in action

Point PPPx at your observation and product files, pick a mode and a solver, and get a positioning solution you can trust.

ZIM2 station processed with the FGO solver using GPS + Galileo observations.

A full day of 30 s data — 2880 epochs — solved in under 1 second.

Bundled example datasets and configuration let you reproduce published results.
