Abstract:

This report describes a ships bridge simulation evaluation of electronic radio aids to navigation displays conducted for the purpose of trading off display information effectiveness with operational requirements and shipboard system cost. The experiment known as RA-1 is the second of a series of experiments which are addressing DIGITAL, GRAPHIC, PERSPECTIVE and STEERING display formats with various noise and filter characteristics. The first, a miniexperiment of abbreviated length, selected five of the most operationally effective display designs from among 18 original display formats. To these were added two predictor steering displays for a total of seven displays all to be evaluated in the more stringent, full-length RA-1 simulation. As a result of superior pilotage performance shown in this experiment, a true motion, trackup GRAPHIC display with either course or heading vectors is recommended as the benchmark display for inclusion in a future RA-2 simulation. The RA-2 experiment will evaluate the benchmark displays effectiveness in a radio aids to navigation noise environment and as a function of system filtering characteristics and the implementation of gyro aiding. The simulation of the noise environment and system filtering characteristics is evaluated in this report.
