The APS-U R is a popular configuration of the APS-U that provides reliable GNSS RTK Position and data interfaces within a rugged aluminium housing to serve a variety of applications that require accurate position and synchronization with other sensors.

The APS-U R has a modular designm with leading GNSS technology for precise RTK position together with 1PPS and Event marker interfaces to directly correlate all measurements on GPS time within seconds after startup. For RTK, the APS-U R has an integrated UHF transceiver and a GSM cellular modem.

In addition to RTK, the APS-U R also features L-Band corrections from TERRASTAR D for 10 cm accuracy utilizing Precise Point Positioning without the use of local base stations or RT networks.

All features are easily configurable via a simple on board web interface. More detailed GNSS configuration is also accessible via the web interface for expert users.

The rugged APS-U R may be used on a variety of machine installations including construction machines, mapping vehicles, and vehicle platforms that utilize accurate position to improve their efficiency.
