On-The-Fly Kinematic GPS Results Using Full-Wavelength Dual-Frequency Carrier Ranges

Benjamin W. Remondi

Abstract:	In recent years rapid and reliable "On-The-Fly" (OTF) kinematic GPS initialization has been an important research and development activity for both the National Oceanic and Atmospheric Administration and the U.S. Army Corps of Engineers Topographic Engineering Center. The Federal Aviation Administration has shown a strong interest in this technology as well. Early OTF results were based on either single frequency carrier ranges or dual frequency carrier ranges but with L2 squared. When P code observations were used the OTF initialization time became tremendously shorter, more reliable, and computationally faster. The focus remained, however, on La-squared processing due to an earlier decision to operate without knowledge of the Y code. With the introduction of GPS receivers which provide full-wavelength Ll and L2 carrier ranges without knowledge of the military codes, civilian OTF kinematic GPS has advanced substantially. I shall present OTF kinematic GPS initialization results based upon full-wavelength dual-frequency data: some of these are P code data and others are based upon C/A code receivers which have full-wavelength dual-band observations even in the presence of Anti-Spoofing (AS).
