RELIABILITY OF DIFFERENTIAL CORRECTION RECEPTION IN PORTS
Journal Title: Asia-Pacific Journal of Marine Science&Education - Year 2013, Vol 3, Issue 1
Abstract
Signals from satellite radionavigational system differential station (DGNSS), designed to improve the accuracy of navigation, have been used for over 30 years. Notwithstanding the fact, until present day the data of how reliably the signals are received in ports is lacking. Experimental data processing has demonstrated that the number of differential correction reception failures is unexpectedly large. These occur due to diurnal changes in the lower layers of ionosphere, due to terrain relief, as well as due to radiointerference. Failures can last for hours. The paper gives an analysis of failure diurnal range characteristics and recommendations to overcome these.
