Inexpensive position sensing device
First Claim
1. A position sensing system comprising:
- a GPS position-sensing device, wherein the position-sensing device includes;
a position antenna configured to receive high-frequency signals;
a down converter coupled to the position antenna and configured to convert the high-frequency signals to low-frequency signals;
a position baseband circuit coupled to the down converter and configured to extract raw position data from the low-frequency signals; and
a communication baseband circuit coupled to the position baseband circuit and configured to transmit the raw position data to a portable position-computing device, which converts the raw position data into the location of the position-sensing device,wherein the raw position data is GPS information that needs additional processing for identification of the data'"'"'s corresponding position, andwherein the raw position data is processed by the portable position-computing device into the location of the position-sensing device.

Abstract
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.
