For the equipment for radio navigation (ARN), installed to the automatic spacecraft (KA), also as for ground-based ARN, stands the task of guaranteeing the interference immunity, especially urgent for KA, which are located in orbits higher than GNSS orbit. The most dangerous type of interferences for ARN, installed on KA, are imitation interferences. In the article the versions of the opposition to this type of interferences with the use of methods of the three-dimensional selection of signals and interferences are examined. It shows that goniometric ARN, supplied with multiunit antenna system for the interferometric definition of the attitude of construction axes KA, successfully can reveal and exclude from the working imitation interference signals, ensuring thus noise immunity with the solution both of goniometric and coordinate- temporary problem.
