This company : www.microstrain.com, provides complete IMU modules with RS-232 interface. they claim that the GX2 IMU contains, accelerometers, gyroscopes, magnetometers and temperature sensor, the price for this module begins from 1700$.
:D any body ever used any of this company products for his MAV project?
There is also another company , Honeywell, It provides the same set of products with same functionality, for example, for example TruePoint HMR3500 contains three magnetometers and three accelerometers.
Both of the IMU's claim that they are capable of measuring Yaw, Role and Pitch, the honeywell product is 775$.
well, simply, what is the effect of gyroscopes inside MicroStrain's product? both of the products are cable of being a complete IMU.
