mentioning types of orbit, frequency bands and a block diagram of satellite view of uplink, transponder and downlink section of a communication satellite. National System of Satellite Communication and Broadcast. Of the Republic of Belarus User's antenna cross-pol isolation (for both uplink and downlink) shall be: When the intermediate frequency signal level on transmitter input is constant Why is the uplink frequency higher than the downlink frequency in satellite communication? in satelite uplink frequency is higher than downlink frequency. space communications services to enable NASA's science, Relay Satellites (TDRS) are being prepared for launch. – TDRS-K S-band.
