See it in action

Geodetic GNSS data processing

From RINEX to a solution

Hand PPPx your RINEX observations and satellite products, choose a mode and a solver, and a positioning solution comes back in under 1 second.

High-precision

Achieve centimetre-level kinematic positioning and mm-level static positioning.

Fast

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

Automated

The pppx.sh wrapper automatically downloads the required products and runs processing in one command.
