Assessing the Performance of the Phase Difference Bathymetric Sonar Depth Uncertainty Prediction Model

Realistic predictions of the contribution of the uncertainty sources affecting the quality of the bathymetric measurements prior to a survey is of importance. To this end, models predicting these contributions have been developed. The objective of the present paper is to assess the performance of the bathymetric uncertainty prediction model for...

EUROFIX Regional Area Augmentation System: Reducing spatial decorrelation with Extended DGPS

Eurofix is an integrated navigation system, which combines Differential GNSS and Loran-C. The Loran-C system is used to transmit messages which contain differential corrections for GNSS by additional modulation of the transmitted signals. It has been shown that reliable data transmission with Loran-C stations up to 1,000 km distance is feasible....
