Navigation Data Monitor


Being able to visualise the raw navigation data coming into a system on a moving platform can be invaluable during system installation and commissioning. Actually seeing the incoming data sentences, with information about their frequency, is a crucial step in debugging complex mobile systems. The SPx Navigation Data Monitor tool is capable of receiving a number of fundamental NMEA-0183 sentences and presenting them in a clear and concise fashion. The tool can display the raw sentence string, along with information about its regularity and can also log messages to file.
