PPS GPS: What Is It? And How Do I Get It
Abstract:
Navigation Satellite Timing and Ranging NAVSTAR Global Positioning System GPS provides two positioning services The Standard Positioning Service SPS and the Precise Positioning Service PPS. PPS receivers have the capability of removing the effects of Selective Availability SA and operating in an Antispoofing A-S environment. PPS receivers can obtain absolute, stand- alone, real-time positions accurate to approximately 10 meters, horizontally. In the past, PPS users wore green suits, and SPS users were everyone else. Agencies within the Department of Defense DOD can obtain PPS receivers agencies outside of DOD are writing Memorandums of Agreement MOA with DOD to also obtain PPS receivers. This paper will discuss the capabilities of PPS GPS and how a U.S. Army Corps of Engineers USACE Division or District can obtain them.
