The APS-U Base Station configuration provides reliable GNSS correction data within a rugged aluminium housing that is easily mounted on a tripod or rooftop. The APS-U base is accessible via Ethernet, serial or USB.

For easy installation, the APS-U Base provides ports for rooftop antenna mounts for both GNSS and radio antennae. Configuration is simple via an on-board web interface. For detailed settings, the GNSS is accessible via EThernet for remote status or configuration, in addition to local series, Bluetooth and USB ports.

The Base station is easily setup in the field with the antenna located over a known point to deliver reliable GNSS correction data. With an on-board web interface, base configuration is simple. The GNSS settings are stored and recovered automatically after a re-boot or power cycle.

The APS-U base has a modular design, with leading GNSS technology for precise data within seconds after startup. In addition to Ethernet connectivity, the APS-U Base has an optional integrated transceiver for broadcast via UHF, or serial ports for broadcast via a more powerful external radio.

The rugged APS-U base station may be used on a variety of temporary or permanent installations and securely mounted in any orientation.
