[Via Satellite 10-01-2015] Inmarsat is planning to shift voice and broadband data services for the Europe, Mid-East and Africa region from the Inmarsat-4 F2 (I-4 F2) satellite to Alphasat, and then move I-4 F2 to a new position in order to create a fourth L-band region. To do so, the company has selected SpectralNet from Kratos Defense and Security Solutions’ subsidiary RT Logic to support its L-band TACSAT (L-TAC) mobile satellite communications system. L-TAC delivers Ultra High Frequency (UHF)-like satellite capability for use with existing UHF tactical radios to approved government customers. SpectralNet’s plug-and-play capability enables Inmarsat to extend L-TAC services across additional satellites.
The Inmarsat ground system uses SpectralNet’s dynamic frequency conversion to transition voice and broadband data services from I-4 F2 to Alphasat. Following transition of all voice and data services, I-4 F2 will be flown to an orbital position for L-band coverage over 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.
