The Trimble® Catalyst™ GNSS Positioning Service is a positioning solution for Android phones enabling simplified, affordable, and precise location information to Esri field apps like Field Maps, Survey 123, and more. Catalyst uses a USB-powered GNSS antenna (the Catalyst DA1 antenna) to track GNSS signals, and computes position information directly on your phone. Currently this service is available for Android devices only, but can be used with any location-enabled software including Esri Collector, Field Maps, and Survey 123. The Catalyst service is an all-in-one positioning service—users simply pick the accuracy level that their workflow requires (with pricing tiers based on accuracy from 1 cm up to 100 cm available), and the Catalyst service figures out the rest. There is no need to subscribe to or configure additional services—the Catalyst subscription includes real-time corrections and configures these automatically using the Trimble Corrections Hub. The lightweight, compact size of the DA1 antenna makes it easy to carry and stow anywhere so it’s always ready to go whenever you need it for your Esri application.
