ViaSat has been awarded a contract for the supply of additional LinkWayS2 IP network modem system to the US Department of Defense (Dod) in an effort to upgrade its tactical communications infrastructure.
Under the $4.5m contract, the company will deliver an unspecified number of LinkWayS2 units to help replace the department’s existing LinkWay2100 series hardware, which has been in use since 2003.
ViaSat Tactical SATCOM Networks general manager Bill Connelly said: "In numerous at-the-halt and on-the-move network demonstrations, LinkWayS2 has maintained its excellent latency and jitter performance in full mesh configurations at the industry’s highest MF-TDMA (multi-frequency, time division multiple access) throughput."
The system provides true network-centric connectivity by seamlessly integrating voice, video and data applications with enhanced operational flexibility compared with the hub-based satellite network systems.
Apart from direct terminal-to-terminal connections, LinkWayS2 also features a second demodulator to obtain simultaneous DVB-S2 broadcast or multicast traffic from global broadcast system (GBS) in-theatre transmitters.
Additional features include a DoD-approved transmission security (TRANSEC), increased transmission throughput, advanced modulation and forward error correction, as well as open standards-based Turbo coding to offer cost-effective communications.
The system demonstrates 100% backwards-compatibility with the existing LinkWay2100 series modem, and has been regularly ordered by the US Army and Marine Corps for a range of military programmes, including regional hub nodes (RHN), deployable Ku band earth terminals (DKET), and support wide area network (SWAN).
