Abstract: A integrated position determination network including a position determination system and a radio relay system is disclosed which locates the precise location of the position determination system. The position determination system incorporates the radio, the power source and the GPS receiver and all necessary electronics into a single housing. Similarly, all of the components of the radio relay are integrated into a single housing. Many of the components of the position determination system and the radio relay system are interchangeable. Thus, a position determination system and radio relay system which use common components is obtained. The use of common components lowers the cost of manufacture and the cost of maintenance. In addition, interchange ability of components allows for great flexibility in designing a GPS network and in performing real time kinematics operations.

Abstract: An antenna for radiating toroidally is disclosed. The antenna may be fabricated to conform with any size of system. The antenna may be placed around an electronics package or a structure to radiate toroidally around the electronics package or structure. The antenna is formed of a strip of copper which includes a number of slots. The slots are disposed longitudinally within the strip of copper such that, upon the application of power to the copper strip, the antenna radiates toroidally. A method for making an antenna that conforms to the size and shape of a particular system is also disclosed.
