TerraStar offers a range of positioning services enabling clients to choose the most suitable for their particular project.

We operate, maintain and control our own network of over 80 GNSS reference stations to ensure maximum operational reliability.

Our Services include:

TERRASTAR-C is an advanced GNSS correction dataset delivered globally from our high availability infrastructure. The TERRASTAR-C dataset contains information that enables carrier phase ambiguities to be resolved to their true integer values within the receiver position solution, further improving positional accuracy and increasing the robustness of the end user solution.


TERRASTAR-D  - a precise positioning service designed to deliver decimetre level position accuracy, globally. The service is based around Precise Point Positioning (PPP) - a technique where all GPS system errors are removed or minimised by direct calculation, precise modelling or estimation.
