Positioning satellite system for measuring position of signal source

Image Number 4 for United States Patent #6680696.

A satellite system includes a signal source located on a surface of the earth, a surface of water, or in air; an orbiting satellite for measuring a position of the signal source, having a GPS receiver which receives a GPS signal from a GPS satellite system to measure the position of the orbiting satellite, a frequency measuring device for receiving the radio wave signal emitted from the signal source to measure the frequency thereof, a memory for storing frequency data and position data, and a transmitting device for transmitting the data stored in the memory toward the earth; and a ground station, having a signal receiving device for receiving the data transmitted from the orbiting satellite, including a computer for calculating the position of the signal source based on the data received by the signal receiving device.
