Telemetry

Rugged, highly durable, airborne telemetry solutions for Aircrafts, Parachutes, Projectiles and Space applications.

OVERVIEW

Telemetry is a remote sensing technique wherein parameters such as velocity, altitude, temperature, etc. are measured, and the results transmitted to a distant station where they are displayed, recorded and analyzed. The transmission media may be air, space, copper wire or fiber cable, depending on the application.

Telemetry modules and systems gather and process critical information on-board spacecrafts, aircrafts, projectiles and UAVs. Mistral provides custom engineering services for designing airborne telemetry solutions compliant with IRIG 106, Class 2 specifications that support a variety of video, data and command & control link needs that meet all perquisite environment and performance requirements.

The airborne telemetry solutions are built to function under the most severe conditions of defense and aerospace applications. We design telemetry solutions that record and transmit data to remote receiving stations on the ground which process and display it for further analysis and decision-making.
