Modernized Ground-Controlled Approach (GCA) system RSP-10MA is intended to ensure flight safety of aircraft and helicopters within terminal airspace, obtain positional information and guide aircraft to a safe landing in normal and adverse weather conditions. RSP-10MA combines primary and secondary radars, and Precision Approach Radar (PAR).Primary channel of RSP-10MA operates in L-band (ICAO), secondary channel uses standard frequencies for RBS (interrogation – 1030 MHz, response – 1090 MHz) and Eastern UVD (interrogation – 1030 MHz, response – 740 MHz). Primary and secondary channels work on a common antenna. Precision Approach Radar performs vertical and glide path guidance and operates in X-band.As a result of modernization the radar′s detection performance is efficiently improved. Modernized radar features automatic tracking capability as well as data receiving from other radar sensors. Data can be exchanged over a variety of communication channels in approved format.
