Satellite Ka Band Link Budget

This communication satellite is designed for ka band frequency for broadband communication in non geostationary orbit ngso with altitude of 1200 km.

Satellite ka band link budget.

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 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. 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.

Tooway out link budget outlink from gateway hub to remote customer vsat site. Uplink from gateway bw 1030 mhz. 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.

The default figures refer to a 4mhz wide carrier from a remote site to the hub. Generic ka band link budget. Those are transmitting power and receiving power calculations. 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.

Return link from vsat remote to the teleport. It is these differences that i will explore to characterize their. The satellite has limits in both antenna gain and available power.
