Inexpensive position sensing devices that allow widespread use and availability of position information are disclosed. One embodiment of the position-sensing device acquires, down converts and extracts raw position data from position signals. Then, the position-sensing device wirelessly transmits the raw position data to a position-computing device, which converts the raw position data into the position of the device. The position-computing device can also receive auxiliary information from auxiliary sensors, and perform analyses based on the position and the auxiliary information. The position-computing device can re-transmit the position and auxiliary information to a remote site for further analysis and/or central storage. The remote site can also download information to the position-computing device. The position-computing device can also control an actuator to perform an operation.
