Precise positions from your GNSS data, processed at JPL

The Automatic Precise Positioning Service (APPS) accepts GNSS measurement files and applies the most advanced positioning technology from NASA's Jet Propulsion Laboratory to estimate the position of your receivers. Static or kinematic, near real time or most accurate, from a single upload.

GDGPS orbits and clocks

Real-time products from the Global Differential GPS System, plus JPL's daily and weekly precise orbit and clock products.

GipsyX / RTGx

JPL's flagship GNSS analysis software processes every submission, with automatic detection of airborne data and kinematic smoothing.

Multi-constellation

GPS, GLONASS, Galileo, BeiDou and QZSS observations in RINEX 2, 2.11 and 3, static or kinematic.

How it works

  1. Create a free account and verify your email address.
  2. Upload RINEX observation files, alone or bundled with pressure, attitude or antenna calibration files.
  3. Review the automatic checks, approve processing, and download your results when they are ready. Results for many common applications are available within minutes.

Prefer scripts? The Python API and web service give you the same capability from the command line.

Fly, land, send

Fly your survey, land your plane, send us your data files. APPS estimates your flight trajectory and returns results within minutes using JPL's proven kinematic GPS positioning technology.
