Trimble’s new GNSS solution, Catalyst, is comprised of a special GNSS antenna (The DA1) and a monthly subscription to the Catalyst correction service. Users have the ability to choose from 4 different precision levels of corrections. The user can use a number of Trimble applications with the solution, or use a 3rd party application. The SDK is also available for developers that wish to create their own apps. Below is a list of helpful links to guide you through the solution.
