GNSS module for a geodetic handheld device


Reliable RTK positioning with survey-grade accuracy in a smart antenna

Over the last decade TERIA has been providing positioning services across Europe for applications requiring high accuracy. To complement their service offering they decided to develop a high-accuracy positioning device for the survey and GIS market. TERIA evaluated several possible GNSS receivers that would fit their requirements.They needed L-band functionality integrated inside the GNSS module to connect to their existing satellite-based TerriaSat service. Finally, they selected the Septentrio mosaic-X5 for its reliable survey-grade RTK positioning with multipath resilience and high security thanks to anti-jamming and anti-spoofing technology. And all this contained in a small module form-factor with low power consumption ideal for a hand-held.  

TERIA acquired a mosaic dev-kit to test out the module and create a prototype. It was just what they needed. The integration process went quickly and smoothly, there was plenty of online documentation and highly trained Septentrio customer support was there to confirm their schematic design. Welcome PYX: the all-in-one, EU-made positioning device. It was time to put it to the real test against the competition. Under harsh GNSS conditions, under forest canopy and in urban canyons, PYX outperformed its competition by delivering significantly more RTK fixes, while under open-sky conditions the performance was similar to competition.

Validation confirmed that PYX has better positioning performance than similar Trimble and Leica devices in challenging environments.

PYX: bundling high performance GNSS hardware, software and positioning services for a competitive price

  • Sub-cm geodetic grade RTK accuracy for survey or GIS applications including VR and photogrammetry
  • 1 year subscription to high-accuracy SSR positioning service TERIA and TERIAsat
  • RTK base or rover
  • Used on a pole, as a hand-held or the electronics board can be integrated into a drone
  • Full GNSS with 447 satellite signals
  • Up to 100 Hz update rate

The TERIA Network was initiated in 2005 by the French Order of Surveyors with the ambition of providing the profession with a real-time geolocation tool of centimetric accuracy. The idea was to answer the obligation of georeferencing topographic production in a common reference frame. Since then, TERIA has successively developed its services to all geolocation players.
