There are numerous three-axis magnetometer chips on the market, many of
which also have three-axis accelerometers in the same package. Almost all
of them do the ADC on the chip and have a digital interface, typically I2C.
Price is a buck or two in singles. However, they are almost always in
obnoxious to solder packages, like QFNs (aka Quite F*cking Nasty).
Sparkfun, Adafruit, Seeed, and others sell breakout boards, often packaged
with MEMS gyros as well. You'll need to add a microcontroller for apogee
detections etc.
$150 is a lot for what looks like a magnetometer chip, a small
microcontroller, and a firing circuit. However, it's in line with the price
of other RDAS stuff. I guess the HPR market isn't big enough to support the
kind of volume and competition that would bring prices down.

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