The display plane was the plane of the orbit (X-Y plane). The display presented the relative position of the target and the interceptor and the predicted path of the interceptor relative to the target. This display was compared with an alternate display identical in all respects except that no predicted path was presented. Eight subjects were used in a counterbalanced 'transfer of training' experimental design. The results indicated that the predictor display significantly improved operator performance of rendezvous as indicated by lower fuel consumption, less variability in fuel consumption and smoother orbital paths.

Investigation of 'predictor' Displays for Orbital Rendezvous, Program Summary available in PDF, EPUB and Kindle. A series of studies on the development of predictor display techniques for orbital rendezvous is summarized. The purpose of this program was to evaluate alternative predictive display techniques for orbital rendezvous. After an analog simulation of the rendezvous problem was mechanized and a display format developed, two studies were conducted investigating operator efficiency at control of rendezvous utilizing the side looking display format and predictor display techniques. Also, two display modifications were investigated: a reduced display size and, the addition of a braking circle. The results of the initial work indicated that operator performance in manual control of rendezvous maneuvers was enhanced by predictor display techniques. The final section of the report outlines the plans for followon efforts. (Author).

Predictor displays for orbital rendezvous present to the pilot target position, interceptor position, and a continuous prediction of the interceptor trajectory relative to the target. Two experiments using rendezvous predictor displays are reported: (1) a comparison of on-line and off-line predictor techniques, and (2) a comparison of intermittent versus continuous updating of the prediction. All conditions tested yielded successful rendezvous performance. Off-line prediction, where the pilot could, at will, interrogate the predictor without expending fuel, was demonstrated to be significantly better than on-line prediction where the pilot could see only his actual predicted path. Intermittent updating produced no significant degradation of performance with update rates as low as once per 50 seconds. (Author).

A simulator study was made of presentations and control requirements for a manned astrovehicle employed in the interception of artificial satellites during the terminal phase of an orbital rendezvous of the satellite. The study was considered in terms of a manned interceptor having a home berth at a manned space station which is in circular orbit 500 miles above the earth. Interceptions were restricted to coplanar conditions and ranges of one-half mile. The results are believed to be generally applicable to conditions wherein the target is in the terminal area. Presentations which do not provide for attitude indications of the intercepting vehicle are not satisfactory. A direct-visual-observation presentation employing a screen, a projected star background, and a projected image of the target provided a feeling of "realism" in tracking and would be a satisfactory pilot-training aid. Use of longitudinal-translation and attitude controls alone is inadequate. Use of translation control alone, parallel and normal to the axis of the intercepting vehicle, is effective; the addition of attitude control enhanced the effectiveness, provided the control was used discriminately. Direct-visual-observation interceptions can be performed effectively without the aid of range and rate-of-closure-of-range meters at speeds up to approximately 50 feet per second; however, higher speeds of interception require the use of these instruments.
