A capability is needed for selected Army users to determine precise position and to navigate reliably worldwide under adverse weather, during day and night, in all climatic conditions, and in an Electric Warfare environment. The desired system must provide instantaneous position location information in Universal Transverse MercatorUniversal Polar Stereographic, Military Grid Reference System, grid coordinates and navigation information. The system should also provide a third dimension altitude in MSL in certain applications. Map, compass and conventional survey equipment in current use will not provide this locationnavigation information to the degree of accuracy and responsiveness required to adequately support the combat user of fielded or emerging tactical systems. Planned systems are intended to provide capabilities to meet this need in general, but not all functional and operational elements can be efficiently supported by those systems being fielded or under development to date. Factors of tactical employment, geographical deployment, degrees of accuracy, and system capacity indicate the need for a mix of systems that can support all positioning and navigation requirements envisioned for the future.
