The objectives of this analysis are to explore potential DCDRS navigational aids and terminal sensors for their impact on the system, and to specify the interface which will be required to permit their use. The nature of each mission to be performed will dictate the navigational accuracies required and, therefore, the selection of a specific class of navigation system. Use of varied navigators should not impact the basic DCDRS design. For the more stringent mission requirements, the required accuracy may be achieved through the use of an integrated subsystem which combines the use of two or more navigation sensors. The interface will receive information from the navigation subsystem and format this data for transmission and processing. It will also accept external navigation update commands and route them to the appropriate navigation sensor. The interface between the navigation systems and the DCDRS system has been explored from the standpoint of integral design. Combining it with the rest of the RPV avionics, interface will result in cost-saving by timesharing of critical components and power supplies. The interface must have the capability of changing the format of the navigation information to the standardized format needed for data link transmission.
