Abstract: | This study determines through digital simulations the effects of two-antenna interference, defined as interference occurring at the ground guidance system antenna between the signals from two antennas located on, opposite sides of a space vehicle. It is demonstrated that errors due to interference during early booster flight are recovered from at booster cutoff; interference produced errors occurring shortly before cutoff are not recovered; and modulating the gain of one spaceborne antenna is beneficial to guidance in the interference region. |
