What is REDtoolbox software?

GNSS Postprocessing and GeoTagging

The software performs a multi-constellation (GPS, GLONASS, Beidou, Galileo) and multichannel (L1, L2, L5) GNSS postprocessing of Base-Rover configurations. Such configurations can be found in many UAV / drone applications such as DJI Phantom 4RTK , M210 V2 RTK, EMLID products, ublox Chipsets and terrestrial 3D ImageVector device.
The corrected GNSS path has accuracies in centimeter level, depending on device hardware, satellite constellation and receipt quality.

Triggers are extracted from the pat and mapped to images. Outputted as plain Text and image EXIF data or in native Agisoft, Pix4d and Google Earth files, these information can be used many other fields of applications., eg. in photogrammetry and documentation.

REDcatch 3D ImageVector

Stores RINEX *.obs path file, Trigger Timestamps and IMU (roll, pitch, yaw) values for image taken. This device is perfect for terrestrial Photogrammetry and documentation in a wide range of application.


During the flight, all necessary data for Triggering and the flight path in RINEX data are stored on the drone. You can use this data directly within our software for GNSS Postprocessing with any Basestation Rinex data available.


You need to respect the usage of a specific gimbal, firmware and DJI Pilot App

u-bloxTM ZED-F9P

Compatible to all u-blox ZED-F9P chipsets. You can use our REDtoolbox Software for Postprocessing PPK and Geotagging in one single software. Included in the software is a manual how to set up the GPS receiver (u-center software settings) to configure the chipset for PPK capabilities.

Emlid Ltd Reach Mapping Kit

Compatible to Reach M+ (L1) and M2 (L1/L2) products

Known for their famous GNSS kit, the *.obs RINEX files stored on the rover can directly be imported to REDtoolbox for GNSS Postprocessing, GeoTagging and the generation of the Photogrammetric Project output files.
