An interesting related project, rather than building hardware … is to write
some open source software to make an existing solution better.
The Altus Metrum TeleMega (http://altusmetrum.org/TeleMega/
<http://altusmetrum.org/TeleMega/>) is a proven rocketry altimeter with 4x
acceleration, 3x gyro, 3x magnetometer, GPS, and barometer, with open source
software. The sensor inputs are Kallman filtered with the apogee detection
algorithm now a dual input filter with barometer and Z accelerometer. Keith
Packard (the author) is looking to further integrate the apogee detection
filter with GPS, but it could also be useful to integrate the magnetometer …
and because it would be a multi-sensor integration - I would guess increase the
overall reliability of the avionics.
This unit is now the amateur rocketry standard avionics for us folks flying
north of 30 km since the software allows defining flight events based on
airframe attitude (e.g. tilt off vertical) - as well as having a good GPS and
70 cm telemetry.
Something to think about for a more software oriented approach that would
improve a number of rocketry projects.

is there an integrated circuit version (chip) on the market by now for the
magnetic sensor copper circuit above?
Thank you.
