The Trimble® Catalyst™ GNSS Positioning Service is a positioning solution for iOS and 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 receiver (the Catalyst DA2 receiver) to track GNSS signals, and computes position information directly on your phone. The service is available for iOS and Android devices and can be used with any location-enabled software including Esri ArcGIS Field Maps, Collector, 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 60 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 DA2 receiver makes it easy to carry and stow anywhere so it’s always ready to go whenever you need it for your Esri application.
