Question

in a C band GEO satellite, the satellite
transponder output power is 20 W,
the satellite antenna gain on axis is 30
db and earth station antenna gain is
59.2 db. if free space path losses at 4
GHz is 195 db, edge of beam loss for
satellite antenna is 2 db, clear air
atmospheric loss is 0.2 db and other
losses 0.5 db. calculate (1-power
received at earth station. 2-noise
power budget in clear air if the noise
bandwidth is 27 MHz and the system
noise temperature is 75 K. 3-C/N ratio
in receiver clean air)
