What makes NMEA a bit confusing is that there are quite a few “NMEA” messages, not just one. So, just like there are all kinds of GPS receivers with different capabilities, there are many different types of NMEA messages with different capabilities. Furthermore, NMEA data can be transmitte...
GPS is a network of 30+ Medium Earth Orbit (MEO) satellites. These satellites continuously send signals over dedicated RF frequencies that a GPS receiver can listen to. By calculating its distance from four or more satellites, a GPS receiver can find out its position in latitude and longitude ...
Inertial navigation can be used as a “fall-back system” that can dead reckon during a time when GPS/GNSS navigation is not available. But in the case of submarines and spacecraft, they are the primary method of navigation. Aircraft and other vehicles often use INS in close conjunction wit...
leading to improved safety and efficiency. NMEA 2000 is used to connect a wide variety of devices, includingGPSsystems, depth sounders, fish finders, and more.
Instead, you create a simple text file containing a list of GPS NMEA messages, copy the text file to the \Program Files\FakeGPS\GPS folder on your device, and then enable FakeGPS. The following is a portion of a sample FakeGPS input file....
