  title: Trimble Mobile Manager Catalyst Corrections API
  description: The Trimble Mobile Manager (TMM) API provides developer interfaces for integrating high-accuracy GNSS positioning from connected Trimble receivers into custom mobile applications. Offers a local REST API for system information and WebSocket stream initiation, plus real-time GNSS position delivery via WebSocket. Supports Trimble Catalyst DA2, R580, R780, R12i, R980, and SP100 receivers. Runs locally on Android or iOS devices where Trimble Mobile Manager is installed.
