Surveillance radar MOST-US, MOST-AS

land-based

Ground satellite fixed communication stations types "MOST-US" AND "MOST-AS" are used to build a fixed aeronautical communication network for the needs of air traffic control. The hardware and software of the satellite communication stations provide for the exchange of the following types of information: voice interaction of dispatchers, as well as officials, centers of the Unified Air Traffic Management System among themselves; provision of interaction between air traffic control centers: integration of local computer networks into a single corporate network, provision of automation planning processes and other activities of the centers; Specification Value frequency range 3650 – 4200 mHz receiving frequency range 5975 – 6475 mHz antenna diameter 5,0 m («MOST-US») / 3,8 m («MOST-AS») receive / transmit polarization circular (right/left) maximum transmitter output power 20 Wt («MOST-US») / 10 Wt («MOST-AS») LNA noise temperature 35-65 oK modulation, coding QPSK/16QAM, Viterbi/Turbo relay speed 256-1024 kbps («MOST-US») / 64-256 kbps («MOST-AS») multiple access type satellite FR (SkyFrame) digital transmission protocols FR, ASYNC, HDLC, TCP/IP and other speech compression algorithms ACELP-CN (8/6 кбит/с), G.729/G.729A (8 кбит/с) operating temperature range -60..+50 С (outside) / +5..+40 С (inside) wind load 25 m/s (regular) / 40 m/s (max), 50 m/s (with receiver) power consumption 800-1500 Wt
