Galileo: The Added Value for Integrity in Harsh Environments
Sensors, 2016 A global navigation satellite system (GNSS)-based navigation is a challenging task in a signal-degraded environments where GNSS signals are distorted by multipath and attenuated by fading effects: the navigation solution may be inaccurate or unavailable.

Performance of Receiver Autonomous Integrity Monitoring (RAIM) for Maritime Operations
, 2016 The use of GNSS in the context of maritime applications has evolved during the past. The International Maritime Organization (IMO) has defined and published requirements for those applications. Comparing the requirements on the one hand specified by ICAO and on the other hand by IMO, significant differences get obvious.
