GSOF messages: Overview

These topics provide information on the General Serial Output Format (GSOF) messages. GSOF messages are a Trimble proprietary format and can be used to send information such as position and status to a third-party device.

This table summarizes the GSOF messages that the receiver supports. When GSOF output is enabled, the following messages can be generated:

Message	Message #	Function

Lat, Long, Height	02	Latitude, longitude, height
ECEF Position	03	ECEF Position
Local LLH	04	Local datum position - latitude, longitude, height
Local ENU	05	Local zone north, east, and height - projection/calibration based
Delta ECEF	06	Earth-Centered, Earth-Fixed Delta position
TPlane ENU	07	Tangent Plane Delta
Velocity	08	Velocity data
