Wow, for about $40 US, that's a really neat way to get attitude information.
Thanks for that.
But it looks like you would have to do some processing of that data on board.
Looks like the device is for aircraft keeping the horizon in the same place,
but for rockets wouldn't the horizon be falling away in all directions?
To stay vertical, you would have to ensure the horizon was falling away at
the same rate on all sides.
That's not the only problem... The sensor wants to be mounted level -
on the tip of your vehicle's nose. Fun times when that plastic case
starts encountering aerodynamic heating...
I imagine it can be hacked by devising some kind of mounting that
looks out through ports of some kind in the skin, but that's going to
require significant testing to ensure your structure doesn't mislead
the sensor.
