Guidelines for NAVSTAR GPS Embedded Receiver Applications

Donald Latterman, Eddy Emile and C. Andy Wu

Abstract:	The Global Positioning System (GPS) is a system of satellites, ground control stations and receivers (or “user equipment”) providing highly accurate, worldwide navigation data. This precise navigation data can be used as an independent output or an input to other navigation, guidance, control, or commuuications systems for both military and civilian applications. The first GPS receivers were developed as separate stand-alone units, integrated with other subsystems through a standard interface or communications bus. With advances in microelectronics technology, basic receiver subassemblies have become smaller allowing the receiver to be embedded in a host electronic subsystem and use some of its functions for support. The embedded GPS receiver offers advantages in size, weight, power consumption and accuracy. Embedding the receiver is most advantageous for: those weapon system applications that require these features and cannot use a standard stand-alone receiver; or where the host system is being replaced and the GPS receiver can be easily incorporated into the new “box.” However, adding unique GPS receiver hardware and software to many host systems, adds burden to the military logistics support system. The NAVSTAR GPS Joint Program Office (JPO) is developing “Guidelines for NAVSTAR GPS Embedded Receiver Applications” for the developers of embedded GPS receivers, to focus industry efforts and maintain interface integrity with the rest of the GPS. This paper briefly touches on Department of Defense (DOD) policy for developing GPS receivers for military applications, discusses embedded applications and advantages, outlines the organization of the guideline, and briefly discusses how GPS military receivers will continue to evolve with future electronics architecture.
