Governments welcome Inmarsat's L-TAC technology

Governments and militaries in more than a dozen countries around the world have successfully trialled or are currently evaluating Inmarsat's new L-TAC service for communications-on-the-move.

Two of the world's largest armed forces have already acquired the satellite communications solution, greatly enhancing their communications capabilities in the field.

Launched officially in July 2013, L-TAC uses Inmarsat's global L-band satellites to extend the reach of UHF military radios.

Small antenna
By affixing a small antenna and sub-system to either a vehicle or a soldier's backpack, military and other personnel can use their existing UHF radios to access global satcoms.

L-TAC has been tested successfully on the move at speeds of up to 70 mph.

“This is a tremendous achievement considering the L-TAC service was launched only two months ago and product modules have only become available this month,” said Andy Start, President, Global Government at Inmarsat.

Comms challenge
“We responded quickly to a demand in the marketplace with an easy-to-use service that addresses a communications challenge for the world's militaries. We are very pleased to see the enthusiasm and uptake to this point.”

UHF military satcoms typically utilises expensive and scarce TACSAT channels. L-TAC's hardware converts the UHF radio signal to L-band to enable transmission across Inmarsat's global satellite network.

Militaries that have trialed the service have praised its voice quality, ease of use and rapid set-up. The service provides clear communications at high speeds, crucial for convoys on the move in hostile environments.

Assured capacity
“The L-TAC service fills a gap in military capability by offering access to assured L-band capacity that significantly expands beyond-line-of-sight communication on the move, at the pause and at the halt,” Andy Start continued.

“In only nine months, Inmarsat developed an offering that is easy-to-use, requires minimal training and is highly cost-effective in that it precludes the need to replace expensive radio equipment – demonstrating our ability to quickly respond to the requirements of our government customers.”

Inmarsat and its partners are showcasing L-TAC at the DSEI exhibition in London from 10-13 September and are sponsoring the ADS Defence Reception on Thursday, 12 September.
