GPS navigation requirements for future mobile ground-based missile systems

It is pointed out that at any given time there are several different missile systems under development. Each of these systems requires some form of guidance or navigation system. In the past, this requirement has been met through the use of inertial sensors. To meet future system requirements, it is envisioned that it will be necessary to incorporate GPS (Global Positioning System) receivers on the launchers and into the missiles. The size, weight, power, performance, number of channels, and cost of these GPS receivers are critical. The authors outline capabilities future GPS receivers will need to meet envisioned US Army missile system requirements
