The Trimble RTX™ correction service is a high‑accuracy, precise point positioning (PPP) system that provides real‑time centimeter positioning without the need for an RTK base station or VRS network.

Survey using satellite‑delivered or internet‑delivered Trimble RTX corrections in open areas where terrestrial‑based corrections are not available. When surveying over a great distance in a remote area, such as a pipeline or utility right of way, Trimble RTX technology eliminates the need to continuously move the base station or, when using satellite‑delivered corrections, to maintain connection to cell coverage.

Trimble RTX accuracy level allows user freely to choose;
Trimble RTX Viewpoint @ 50 cm.
Trimble RTX Rangepoint @ 30 cm..
Trimble RTX Fieldpoint @ 10 cm.
Trimble RTX Centerpoint @ 2 cm.
