Video telemetry module

Video telemetry module for use with Sentinel AAT tracker

This module provides the ability for aircraft who do not have built in support for Sentinel AAT trackers. This brings Sentinel tracking to any other FC's with GPS - e.g. Eagletree, Ardupilot on Matek F405, etc, etc.

This supports analog video systems using OSD / FC that DO NOT already have embedded support for Sentinel AAT

• MWOSD 2.0 has this built in.
• iNAV 3.0 onwards has this built in for FC that have embedded 7456 OSD ic
• A minim OSD with telemetry module firmware is inserted between existing OSD and VTX
• Connections to GPS TX out, supply voltage and vid in / out are required
• The module Auto detects GPS baud rate
• The module determines the home position, detects launch and sends AAT telemetry data over the video signal
• The module will overlay a small status indicator.
• in flight loss of GPS data indicator

OSD visible status indicator:

• Flashing * > 2hz = waiting GPS data or fix
• Flashing * 2hz = fix obtained, waiting stable home set position
• No indicator = ready to launch.
