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.

GSOF messages are in a binary-based format.

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