LAUNCH WINDOWS FOR ORBITAL MISSIONS

reportActive / Technical Report | Accession Number: AD0601072 | Open PDF

Abstract:

A great many orbital missions involve launching a vehicle into a particular earth-referenced plane. The launch window is defined as the time span around the nominal launch time during which the vehicle may be launched and the target plane achieved within a specified additional ideal velocity budget. The paper presents analytical formulations for the launch window as functions of the additional Delta V budget and other parameters for fixed and for variable launch azimuths. The effect of launch azimuth constraints e. g., for range safety on the launch window is investigated and several related problems are discussed.
