The Trimble Catalyst software-defined Global Navigation Satellite System (GNSS) receiver for Android devices is now available through Trimble's global distribution network. Customers can now access Positioning-as-a-Service to collect geo-location data with Trimble or third-party apps on smartphones, tablets, and mobile handhelds. When combined with a small, lightweight, plug-and-play digital antenna and subscription to the Catalyst service, the receiver provides on-demand GNSS positioning capabilities to transform consumer devices into centimeter-accurate mobile data collection systems. It can be used for topographic mapping and ground control for unmanned aircraft systems (UAS).
