designed to recieve and phase track signals
transmitted by satellites of the NNSS. These signals
are processed to obtain navigation information that is
monitored on video displays and used elsewhere for
ship navigation.
The AN/WRN-5 is designed to be used in various
configurations as described below. Each of these
configurations is defined by options in external
equipment used or variations in inputs and outputs.
The options available for alternative configurations
are:
