Group delays (GDs) are errors affecting Global Navigation Satellite Systems (GNSS) due to
non‐idealities of the satellite or the receiver hardware and can compromise safety critical …

Time-Receiver Autonomous Integrity Monitoring (T-RAIM) algorithms assess the reliability of
the timing solution provided by a Global Navigation Satellite System (GNSS) timing receiver …

Advanced Receiver Autonomous Integrity Monitoring (ARAIM) is a concept that extends
RAIM to other constellations beyond GPS. ARAIM will enable the integration in the position …

Both Galileo E1 OS and GLONASS L1 signals require a wider pre-correlation bandwidth
than GPS C/A. The GLONASS channels are uniformly spaced on a frequency division grid …

This paper provides an update on two essential aspects related to the future support of
Galileo to Advanced Receiver Autonomous Integrity Monitoring (ARAIM) service …

This paper provides an update on three essential aspects related to the future support of
Galileo to Advanced Receiver Autonomous Integrity Monitoring (ARAIM) service …

In the future a Global Navigation Satellite System, like Galileo, will not only provide
positioning and timing services, but it may also provide integrity service. The integrity risk …

GPS, Galileo and GLONASS are preparing for the transmission of signals in two protected
frequency bands (L1, and L5). The combined use of such signals and the verification of their …

In the near future of multiconstellation and multifrequency GNSS signals, the users will
experience a significantly increased accuracy, thanks to the larger number of satellites in …

GPS and Galileo are expected to serve as navigation sources for a variety of applications.
The most stringent performance requirements are derived from safety critical applications …
