Satellite Ka Band Link Budget

Ka band satellite communications link budget trade off analysis mitigation technique muche mor than at lower frequencies.

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. In general these calculations are called as link budget calculations the unit of power is decibel. Return link from vsat remote to the teleport. In satellite communication systems there are two types of power calculations.

In this paper we design the link budget of communication satellite. The satellite has limits in both antenna gain and available power. This is a generic simulation of a satellite with ka band spot beams with multiple inbound carriers from the vsat remotes. It is these differences that i will explore to characterize their.

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. This communication satellite is designed for ka band frequency for broadband communication in non geostationary orbit ngso with altitude of 1200 km. Generic ka band link budget. Tooway out link budget outlink from gateway hub to remote customer vsat site.

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. First let us discuss the basic terminology used in link budget and then we will move onto explain link budget calculations. The ability of this communication satellite depends on the strength of the signal and the amount of thermal noise.
