Book excerpt: Inexpensive Global Location and Tracking Systems are currently being designed to provide the civilian market low-cost radio position determination. This paper discusses two possible designs. The first design employs 3 or 4 satellites, depending on whether altitude is known a priori, each transmitting continuous ranging signals. The user transceiver receives the ranging signals, measures the time differentials of the receipt of the signals and transfers this information to a control station via a satellite link. The control station computes the user position from this data and sends the position coordinates back to the user via another satellite link. In the second design, each user transceiver transmits a unique code to the control station via the 3 or 4 satellite links, again depending on whether the altitude is known a priori. The control station measures the time differentials of the receipt of the signals and determines the user position. This position information is then transmitted back to the user via a satellite link. Keywords: Geostationary satellite navigation; Position determination; Thesis.
