  title: Trimble Mobile Manager 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.
