The evaluation of kinematic GPS/GLONASS when the radio wave is masked [PDF]

, 2009
When we measure the rolling and pitching such as fishing boats by GPS, it is necessary to set up at least 4 antennas. However, in most cases, around the antennas there are structures cut off the radio wave from the satellites.
