TeleMega v6.0 GPS Flight Computer

Altus Metrum TeleMega

This is a high-end recording dual-deploy altimeter for high power model rocketry with integrated GPS and telemetry link. The features included make TeleMega the ideal choice for complex projects including sustainers on multi-stage projects. In particular, pyro events are configurable and can be based on time and various flight events and status, including angle from vertical.

Features
