Satellite Ka Band Link Budget

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.

Satellite ka band link budget.

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. The default figures refer to a 4mhz wide carrier from a remote site to the hub. Tooway out link budget outlink from gateway hub to remote customer vsat site. In satellite communication systems there are two types of power calculations.

Uplink from gateway bw 1030 mhz. Those are transmitting power and receiving power calculations. The ability of this communication satellite depends on the strength of the signal and the amount of thermal noise. This is a generic simulation of a satellite with ka band spot beams with multiple inbound carriers from the vsat remotes.

It is therefore important that there is appropriate planning for the implementation of well designed ground systems network links reliability and resources so as to mitigate these adverse weather effects. The satellite has limits in both antenna gain and available power. First let us discuss the basic terminology used in link budget and then we will move onto explain link budget calculations. Return link from vsat remote to the teleport.

This communication satellite is designed for ka band frequency for broadband communication in non geostationary orbit ngso with altitude of 1200 km. Ka band satellite communications link budget trade off analysis mitigation technique muche mor than at lower frequencies. Generic ka band link budget.
