Information obtained is from the GPS (Not Compass) usually providing your COG and SOG. It will provide a bearing and distance. There are both static and dynamic info. provided to other receivers If you are not moving the "dynamic" information is suspect and cannot be determined. In other words the gps does not know what direction you are pointed but does know where you are. Bear in mind that all of the internet tracking sites use contracted antenna either on other vessels or land based to receive their data which is effected by line of sight and locations. Other vessels within line of sight will received your data more readily than perhaps the land based or contracted ship antenna.
