General Dynamics enhances WIN-T with Next Gen PoP

18 October 2017

General Dynamics Mission Systems (GDMS) has completed work to incorporate its Next Generation Point of Presence (Next Gen PoP) enhancement to the Warfighter Information Net-Tactical (WIN-T) Increment 2 (Inc 2).The General Dynamics Mission Systems HMMWV-mounted Next Gen Point of Presence (PoP), clearly showing the space on the right of the cabinet which has been freed up for additional capabilities.

The Next Gen PoP effort was first announced in 2016 and significantly reduces the size, weight, and power (SWAP) requirements of the installation.

It provides satellite communications (satcom) on the move ability, high capacity line of sight (HCLOS), as well as VHF communications, and is intended to support a mobile command post. The HCLOS antenna is an upgraded version of the original WIN-T Inc 1 version, with a lower profile and greater throughput. A GDMS representative told Jane’s that the possibility of a lower profile satcom antenna is being examined.

The NextGen PoP improvements leverage the work done to reduce the SWAP of the WIN-T Tactical Communications Node (TCN) from a five-ton truck to a High Mobility Multipurpose Wheeled Vehicle (HMMWV) installation, with system components reduced by approximately 50% and power consumption reduced by 7%. The use of AC power has also been eliminated, with the number of electrical cables cut by about 30%. There are commensurate savings in lifecycle costs.

Much of this has been achieved through virtualisation and simplification. Routing, switching, and computing components for the local and wide area network have been reduced by substituting the General Micro Systems SB2002-SW Blackhawk switch/router.

The new HMMWV-mounted installation has an increased number of external interfaces to support additional equipment. This includes a simple external fibre-optic connection for an AN/TSC-185 Satellite Transportable Terminal (STT). The GDMS representative told Jane’s that feedback from users had indicated an occasional need for a simple connection with the towed STT, in addition to the integral satcom antenna.
