Tejas Flight Computer

Software Design

I prefer to sail in a bad ship with a good captain rather than sail in good ship with a bad captain.

TEJAS flight computer is to aid a model rocket with recovery and data logging. It is entirely based on arduino with MPU6050 and BMP280 for orientation and altitude data. The development of TEJAS FC took over 3 months. It was fundamentally designed with no blocking code so as to make it a fault taularent system to some degree.

Challenges:

• Low memory
• Less Processing Power
• Delayed Apogge Detection
• Realtime telemetry
