As stated in prev posting, GPS _can_not_ deliver bearing of device at all. Imagine having the GTA in your pocket while moving - there's not the faintest relation between movement vector as seen by GPS and bearing of GTA. > > Gyroscopes is what you look for. ;) > Accelerameters don't see rotational movings. Though gyro won't help here at all, i think TWO 3D-accelerometers placed some distance from each other in a system make a nice gyro with the aid of some mathematics in driver. IIRC there was mentioned more than one acc-meter for the GTA. I thought that's exactly for this purpose. jOERG _______________________________________________ OpenMoko community mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/community
