Robust, Satellite-Based Positioning

SAT/SAT-D: reliable GNSS/D-GNSS position detection

SAT and SAT-D belong to Symeo’s robust family of GNSS solutions that offer reliable, satellite-based positioning. SAT-D features an added level of accuracy by relying on a correction signal generated by a Symeo D-GNSS reference station installed at a fixed location.

The GNSS receiver can be mounted on the roof of the vehicle, in the interior or in a separate control cabinet.

Typical applications include positioning and telemetry data capture for free-ranging vehicles operating at container terminals, or cranes and transport vehicles used by the steel industry.

The Symeo SAT solution is a GNSS satellite-based positioning system. The SAT-D system relies on input from a correction signal generated by a reference station installed at a fixed location to provide < 1 m accuracy.

The SAT and SAT-D receivers can be mounted externally, inside the vehicle or in a separate control cabinet. The units are maintenance-free, contain no moving parts and can withstand harsh weather, dirt and vibrations.

The measurement unit features flexible options that permit capturing and analyzing additional telemetry and vehicle data such as weight, lift height or loading status, depending on the application. By adding a second GNSS antenna, this system can accurately determine the orientation of the vehicle even at slow speeds or when idling.

SAT and SAT-D, which operate with state-of-the-art (D-)GNSS technology, utilize the GPS and Glonass satellites to provide position detection applications a high degree of reliability and accuracy.

The “D” in D-GNSS stands for differential, which relates to a process for improving the reliability of the positioning system by using a GPS correction signal from a Symeo reference station installed at a fixed location on the grounds. Using the correction data, the system compensates for potential atmospheric interference that can occur with satellite signals.

The captured data can be made available via a Ethernet standard interface.
