ViaSat demos full mesh MF-TDMA DAMA networking over WGS

CARLSBAD, USA: ViaSat Inc. has successfully demonstrated full-mesh multi spot beam (Fan In/Fan Out) operations over the government-owned WGS-1 satellite with LinkWayS2 equipped earth terminals configured with the WIN-T software baseline.

This demonstration was a collaboration between the US Army and ViaSat aimed at improving the efficiency of multi spot beam operations over the Wideband Global Satcom (WGS) constellation.

LinkWayS2 equipped earth terminals in the Guam, Hawaii, and West Coast WGS beams participated in the week long demonstration. Using a single TDMA carrier, full-mesh connectivity was demonstrated between all traffic terminals, both interbeam (e.g., Hawaii-to-Guam, Hawaii-to-Roberts, etc.) and intrabeam (e.g., Hawaii-to-Hawaii, Roberts-to-Roberts, etc.).

To further demonstrate the flexibility of the LinkWayS2 system, it set up the same connections using multiple TDMA carriers configured in the same bandwidth segment on WGS-1. The system is scalable from one TDMA carrier to multiple contiguous cross-beam TDMA carriers and multiple non-contiguous in-beam carriers.
