ViaSat Successfully Demonstrates Full Mesh Satellite Communication at Ka-band Using ViaSat LinkWay(S2) MF-TDMA Satellite Modem
ViaSat Successfully Demonstrates Mesh Satcom COTM Over Ka-band On Optus C1
First Ka-band COTM networking using LinkWay(S2) modems
ViaSat Inc. (Nasdaq:VSAT – News) has successfully demonstrated full-mesh satellite communications at Ka-band between an Australian Army deployable 1.0-metre Compact Transmit Receive Suite (CTRS) terminal located at the Defence Science and Technology Organisation (DSTO) and a 48-cm communication-on-the-move (COTM) terminal located at BAE Systems Australia using a ViaSat LinkWay®(S2) MF-TDMA satellite modem. This demonstration further shows the ability of the LinkWay(S2) modem to simultaneously support satellite communications with fixed site, at-the-halt, and on-the-move terminals within a single tactical LinkWay network.
The full-duplex mesh connection streamed high-definition video simultaneously in both directions between remote sites while the mobile satcom antenna was exercised on a multi-axis, full motion platform using the steerable Ka-band spot beam on the Optus C1 satellite. The LinkWay(S2) master reference terminal for the demonstration originated from a fixed terminal with a DVB-S overlay sourced from another Ka transponder on Optus C1.
“This is the first demonstration of Ka-band broadband communications-on-the-move using standard, off-the-shelf LinkWay(S2) modems,” said Peter Weissmann, ViaSat business development manager for Australia and New Zealand. “This demonstration follows several very successful vehicular and airborne Ku-band mobile satcom demonstrations recently conducted in the U.S. It was also the first demonstration of the optional DVB overlay in a mobile setting, showing the versatility of the LinkWay(S2) platform.”
ViaSat’s mobile satcom products and technologies support customers that operate on its Yonder® worldwide service as well on their own networks.
The LinkWay full-mesh communication system has been a satellite networking workhorse for U.S. defense over many years and with the addition of this new COTM capability, will increase its ability to provide network-centric operations, particularly over the Wideband Global Satcom (WGS) constellation.
The COTM antenna was designed and developed as a concept technology demonstrator by EM Solutions Pty Limited based in Brisbane, Australia under contract to DSTO and has been successfully tested on an Australian Bushmaster Personnel Mobility Vehicle (PMV).
