Included are ground system configurations, station view periods, and a discussion by station and view period of all tracking data, i. e., angular and doppler, taken by the tracking stations. A summary is given of the tracking data which were actually used to determine the spacecraft orbit and the noise statistics of these data. w VI v L JPL TECHNICAL REPORT NO. 32-719 1. INTRODUCTION This Report sets forth the results of the analysis of the Agena/spacecraft separation occurred, and successful tracking performance of the Deep Space Instrumentation completion of further on-board events resulted in Earth Facility (DSIF) during the Ranger VZI mission. It deals and Sun acquisition by the spacecraft. with the preflight preparations of the DSIF stations, the results of the postflight analysis of the DSIF station flight Initial DSIF acquisition by Station 59 occurred at operations, and the postflight tracking data reduction by 17:20:50 GMT, and the DSIF stations tracked the space- the orbit determination program (ODP). craft continuously from that time until impact. Actual station tracking periods, as well as nominal station view periods, are listed in Table 1. Initial orbit computations A. History of the Mission showed that the spacecraft would impact the Moon. To The Ranger VZZ spacecraft was launched with an secure more favorable terminal conditions a midcourse Atlas/Agena B booster system from Cape Kennedy on maneuver was executed during the period 10:27:09 to July 28, 1964.
