All spoofer attacks have different requirements, impacts, success rates and objectives; therefore,
to assess the threat and to develop appropriate counter measures, a clear classification …

Interference signals degrade global navigation satellite system (GNSS) performance and
must be mitigated. Chirp signals can be mitigated with an adaptive notch filter (ANF), but the …

This paper evaluates the implementation of a low-complexity adaptive full direct-state Kalman
filter (DSKF) for robust tracking of global navigation satellite system (GNSS) signals. The …

This paper evaluates the performance of robust adaptive tracking techniques with the direct-state
Kalman filter (DSKF) used in modern digital global navigation satellite system (GNSS) …

Global navigation satellite system (GNSS) transmit signals with code-division multiple access
(CDMA) sequences. A receiver should know these sequences such that the signal can be …

Global navigation satellite system (GNSS) receivers use tracking loops to lock onto GNSS
signals. Fixed loop settings limit the tracking performance against noise, receiver dynamics, …

This paper presents a loop-bandwidth control algorithm for adaptive scalar tracking loops
used in modern digital global navigation satellite system (GNSS) receivers. This algorithm …

Interference signals degrade and disrupt Global Navigation Satellite System (GNSS) receivers,
impacting their localization accuracy. Therefore, they need to be detected, classified, and …

Proper signal conditioning is crucial for reliable Global Navigation Satellite System (GNSS)
navigation. Signal conditioning includes correcting receiver front-end distortions, shaping …

For the typical user of positioning and navigation applications, a precise GNSS receiver is a
black box which delivers not well specified raw measurements with very reduced …
