Satellite Ka Band Link Budget

Uplink from gateway bw 1030 mhz.

Satellite ka band link budget.

Those are transmitting power and receiving power calculations. In satellite communication systems there are two types of power calculations. The satellite has limits in both antenna gain and available power. Return link from vsat remote to the teleport.

It is these differences that i will explore to characterize their. Tooway out link budget outlink from gateway hub to remote customer vsat site. The ability of this communication satellite depends on the strength of the signal and the amount of thermal noise. Ka band satellite communications link budget trade off analysis mitigation technique muche mor than at lower frequencies.

In general these calculations are called as link budget calculations the unit of power is decibel. In this paper we design the link budget of communication satellite. The default figures refer to a 4mhz wide carrier from a remote site to the hub. This is a generic simulation of a satellite with ka band spot beams with multiple inbound carriers from the vsat remotes.

First let us discuss the basic terminology used in link budget and then we will move onto explain link budget calculations. Clearly high throughput satellites hts whether ku band or ka band have much higher gain antennas and also much more available power due frequency reuse offering many times more capacity than a wide beam. The outlink comprises 4 carriers per beam comprising 3 carriers of 52 msps plus 1 carrier of 40msps making a total used bandwidth of approx 206 mhz out of the allocated 236 mhz per beam.
