Stand-alone vs. embedded GPS user equipment: the exploration of new standards

Configurations of a stand-alone receiver chassis and embedded receiver module sets to meet the diversity of high-performance GPS (Global Positioning System) applications are addressed. The ITT design approach is shown to meet these applications. Specifically, the ITT 3/8 ATR short-short (PPS-capable) production receiver is available in a 230-in² volume to meet stand-alone receiver chassis requirements. An embedded GPS receiver (PPS-capable) consisting of individual modules from 9052 receiver requiring only 82 in³ is also described. Technology insertion is described for the 3/8 ATR stand-alone receiver as a cost reduction and reliability preplanned product improvement. Technology insertion is also described for embedded configurations resulting in a single SEM-E GPS receiver (PPS-capable) module standard requiring only 23 in³
