Improved and newly devised techniques for single carrier operation mode are employed based on the DVB-S2X standard. The objective is to demonstrate clear performance and efficiency advantages compared to operation with multiple carriers per transponder.
Existing tools for calculating exact link budgets shall be enhanced to allow performance and throughput prediction based on measurements under controlled conditions.
The performance target is to achieve a throughput of more than 1 Gbit/s at IP level. Therefore all components deployed within this activity will be enhanced to practically handle such throughput.
In order to realize ultra-high throughput transmission over a satellite wideband transponder newly devised adaptive coding and modulation (ACM) techniques have to be applied. This implies the implementation of feedback loops between demodulator and modulator / encapsulator.
Phase 1 (09/2014 – 04/2015):
Identification of suitable ground and space segment components, state-of-the-art air interfaces or standards suitable to achieve the 1Gbit/s throughput target
Phase 2 (04/2015 – 12/2016):
Implementation of a laboratory test-bed suitable to support more than 1 Gbit/s
Phase 3 (01/2017 – 03/2017):
Verification of performance via on-field-trials through a Ka-Band transponder of Avanti’s HYLAS-2 satellite
