Inmarsat's L-TAC Mobile Comms System Is Extended Via Kratos SpectralNet™

[SatNews] Kratos Defense & Security Solutions, Inc. (Nasdaq:KTOS) announces their company's RT Logic subsidiary has delivered multiple SpectralNet systems to Inmarsat to support the mission critical Inmarsat L-band TACSAT (L-TAC) mobile satellite communications system.

L-TAC delivers a UHF-like satellite capability for use with existing UHF tactical radios to approved government customers at low cost.

SpectralNet’s plug and play capability enables Inmarsat to cost effectively and transparently extend L-TAC services across additional satellites. The Inmarsat ground system uses SpectralNet’s exclusive dynamic frequency conversion to smoothly transition voice and broadband data services for the Europe, Mid-East and Africa region from the Inmarsat-4 F2 (I-4 F2) satellite to Alphasat, Europe’s largest and most sophisticated telecommunications satellite. Following transition of all voice and data services, I-4 F2 will be flown to a new orbital position to create a fourth L-band region, serving the Middle East and Asia. Inmarsat’s L-TAC bridges existing Beyond Line of Site (BLOS) tactical UHF radios through a combination of the Inmarsat L-band satellite networks and SpectralNet.

SpectralNet is the only commercially available product that eliminates the distance constraints of RF transport by digitizing RF signals for transport over IP networks in a way that preserves both frequency and timing characteristics, and then uniquely restores the RF signals at their destination. SpectralNet provides a rich set of additional functionality, such as dynamic frequency conversion, to enable high value uses as demonstrated by Inmarsat.

Executive Comments

"Inmarsat’s use of SpectralNet’s frequency translation capability demonstrates its versatility in a wide range of use cases for managing and transporting RF over IP networks,” said Scott Criley, SpectralNet Product Director.

“SpectralNet gives Inmarsat a reliable capability to extend L-TAC across multiple Inmarsat satellites,” said Chris Ashton, Director, Spectrum Engineering at Inmarsat.  “It has enabled us to seamlessly enhance services to our L-TAC customers in a cost-effective way.”
