Satellite Uplink And Downlink Formula

The uplink frequency range is also used for non satellite military communications mostly aviation which uses analog am and in asia mobile phone traffic which uses narrowband fm.

Satellite uplink and downlink formula.

Up link path loss. The venerable linear satellite ao 7 has a transponder with an uplink between 432 125 and 432 175 mhz. The equation is same as the satellite uplink with a difference that we use the abbreviation d everywhere instead of u to denote the downlink phenomena. Uplink downlink intersatellite links relay satellite relay satellite relay satellite sensor satellite sensor satellite crossover or intersatellite links mission data launch phase tt c tt c satellite ground station tt c tracking telemetry and control the communications architecture consists of satellites and ground stations interconnected with.

Typically at about the 4 5 db contour the beam is starting to drop off rapidly so there will be large variations in uplink g t the uplink sensitivity and downlink eirp as the satellite moves about slightly. Our satellite uplink and downlink service is a key capability that a number of clients have found to add great value to their events. The downlink is between 145 975 and 145 925 mhz. G t ratio indicates figure of merit.

Up link frequency up link frequency is frequency at which ground station is communicating with satellite. The number of db down for the beam edge is a matter of opinion it depends where you want to define the edge. Uplink c n o db hz the up link of a satellite circuit is the link in which the earth station is transmitting the signal and the satellite is receiving it. 1 calculation of uplink path loss.

Strauss media strategies will coordinate either an event uplink or downlink via satellite using our years of experience working with production teams across the nation to coordinate all of the technical logistics. Here s a chart that shows the relationship. Satellite system calculator for modern electronic communication 9 e jeffrey s. Unintended signals from such users will occasionally make their way up to a satellite and be retransmitted on the corresponding downlink channel.

For c band up link frequency is in the order of 6 g hz. Up link path loss depend on up link frequency distance between satellite and ground station. Satellite downlink in this process satellite sends the signal and the earth station receives it. Beasley and gary m.
