To capture a ground track from a GPS device without a live Bentley Map session, use the standalone utility GPS Recorder provided with Bentley Map. The utility can record from either NMEA or Garmin USB devices. It calculates the sequence of positions and all data transmitted from the GPS device to client programs. The GPS session data is saved to a file for playback.

The GPS Recorder window resembles the Global Positioning System dialog. The window has three tabs — Settings, Status, and Position, plus Record, Pause, and Stop buttons.

Before you can interact with recorded GPS session data, you must first select a geographic coordinate system (GCS) for the active model.
