Abstract:	Important issues for automation of ship handling are accuracy, availability and reliability of position, velocity and time. In most cases satellite navigation receivers are used as the primary position fix system in shipping. Accuracy of satellite navigation receivers on board ships can be affected by shadowing from obstructions, reflections, multipath, satellite changing’s caused by ship’s movements or ship’s maneuvering. A support of satellite navigation systems using integrated navigation systems appears reasonable regarding the unreliability of GNSS against jamming. The measurement data of accuracy, availability and reliability are examined under the conditions experienced on board ships. Measurements are made with carrier phase smoothed DGPS/DGLONASS using L1 and RTCM or raw range corrections. Results are verified by carrier phase measurements. Various means of increasing accuracy, availability and reliability are examined using integrated solutions with: (D)GPS with (D)GLONASS; (D)GPS/(D)GLONASS with identification of ship dynamics using ship’s and environmental parameters or their combination with terrestrial navigation systems, e.g. LORAN-C. The integrated software navigation receiver, which has been developed in the project INIS II, offers the possibility to acquire all measurement data in real-time using a common PC. It offers the capabilities of a simulation system including various filter and smoothing techniques applicable to the data, calculation of any combination of measurement data, use of atmospheric correction models, reliability and integrity checks. Any parameter in the simulation system can be changed online. To compare the calculated data several tools to evaluate these have been developed.
