About the most economical way to install a compass is the Dinsmore analog unit.
It has two analog outputs which you will need to do some serious processing
on, they aren't sin and cos, so you have to do a sort of arctan and then
lookup table correction. The device is mechanical so it has some serious
limitations.
At the moment, it is the only choice I know of (in the US), since the Vector
module has been withdrawn.

| (...) Derek, what you need to assess is how stable you need a reading (I guess you want an heading). A compass needs a stable platform to provide you with a decent value. Any acceleration (turning is a kind of acceleration) is going to spoil you (...) (22 years ago, 19-Jun-02, to lugnet.robotics)
