Satellite Navigation Systems
SATNAV
The SATellite NAVigation (SATNAV) system is a highly accurate,
passive, all-weather, worldwide navigational system suitable for
subsurface and surface navigation, as well as for use in aircraft. This
system has been in wide use in the fleet, and is also available to
commercial interests. Because of today’s technology and expertise in
transistors, computers, and miniaturization, this system is extremely
accurate.
SATNAV plotting is made simple because the receiver gives a written
printout of the latitude and longitude of the vessel’s position along with
other information about the satellite pass which gives the navigator
valuable information about the accuracy of that particular satellite pass
and the time of the next pass. The AN-SRN-19 (fig. 8-27) is being
replaced throughout the fleet by the WRN-6 GPS navigation system.
Refer to the SRN-19 operators manual for specific instructions for
system setup.
