Augmentation of GPS with Pseudolites in a Marine Environment By
The augmentation of DGPS with ground-based GPS transmitters (pseudolites, or PLs) was investigated. A simulation analysis was conducted to determine the effects of PL augmentation on DGPS availability, accuracy and reliability measures, using various constant mask angles and a " real-world " horizon (measured at Lake Okanagan, British Columbia) plus a simulated obstruction. Field tests in the m...
متن کاملReal-Time Interference Detection in Tracking Loop of GPS Receiver
Global Positioning System (GPS) spoofing could pose a major threat for GPS navigation ‎systems, so the GPS users have to gain a better understanding of the broader implications of ‎GPS.‎ In this paper, a plenary anti-spoofing approach based on correlation is proposed to distinguish spoofing effects. The suggested ‎method can be easily implemented in tracking loop of GPS receiver...
متن کاملInterference to GPS from UWB Transmitters
Ultra Wide Band (UWB) technology is based on very short pulses of radio energy. In theory, its wide signal bandwidth yields excellent multipath immunity. Hence, UWB has been used in a variety of applications, including communication and ranging, and is expected to see increased use in the future. Since signals from GPS satellites have very low power levels (-130 dBm or -160 dBW) near the surfac...
