Satellite Ka Band Link Budget

In satellite communication systems there are two types of power calculations.

Satellite ka band link budget.

Return link from vsat remote to the teleport. 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. This communication satellite is designed for ka band frequency for broadband communication in non geostationary orbit ngso with altitude of 1200 km.

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. Tooway out link budget outlink from gateway hub to remote customer vsat site. In general these calculations are called as link budget calculations the unit of power is decibel. This is a generic simulation of a satellite with ka band spot beams with multiple inbound carriers from the vsat remotes.

The default figures refer to a 4mhz wide carrier from a remote site to the hub. Ka band satellite communications link budget trade off analysis mitigation technique muche mor than at lower frequencies. 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 satellite has limits in both antenna gain and available power.

In this paper we design the link budget of communication satellite. Those are transmitting power and receiving power calculations. It is these differences that i will explore to characterize their.
