متن کاملAttitude Determination Methods Using Pseudolite Signal Phase Measurements
In this paper, new attitude determination algorithms using pseudolite signal phase measurements are developed and presented with realistic simulations. Pseudolite signals are used to replace GPS signals which are often not available due to blocking by nearby large structures, for example a crew return vehicle under the International Space Station. A new observation model needs to be applied bec...
متن کاملGNSS/Pseudolite Signal Re-Acquisition with the aid of INS in Short Signal Blockage Scenarios
Based on the concept of ultra-tight integration of GSSS, Pseudolite (PL) and Inertial Navigation Systems (INS), this paper proposes a method to execute quick GNSS/PL signal re-acquisition in short signal blockage scenarios. The key aspect of this method is that the INS measurements are used not only to aid the tracking loops, but also to aid re-acquisition when a signal blockage happens. The re...
متن کاملPseudolite Augmentation of GPS
1.1 GPS – benefits & constraints The Global Positioning System (GPS) is an all-weather, global, satellite-based, roundthe-clock system developed by the U.S. Department of Defense, which since the early 1980s has been available to the civilian community and has truly revolutionized navigation, surveying and geodesy. GPS is based on a constellation of up to 30 satellites orbiting the Earth, broad...
متن کاملProposed Airport Pseudolite Signal Specification for GPS Precision Approach Local Area Augmentation Systems
The availability and continuity of accuracy and integrity are major concerns for GPS-based precision approach and landing systems without augmentation. Thus, following the lead of the FAA baseline Local Area Augmentation System (LAAS) architecture that includes pseudolites, RTCA Special Committee 159 Working Group 4a for GPS/Precision Landing Guidance has set up an Airport Pseudolite (APL) subg...
