MILSTAR SMART-T

The Secure Mobile Anti-Jam Reliable Tactical Terminal (SMART-T) is a HMMWV mounted, EHF terminal that provides multichannel range extension for MSE at division and corps. The terminal operates at T-1 (1.544 Mb/s) over the MILSTAR satellite and at the low (75 Bps to 2,400 Bps) and medium (4.8 Kb/s) EHF data rates over MILSTAR and the EHF packages on FLTSAT and UFO. SMART-T will replace the multichannel GMF terminal for hard core and core users. It provides Low Probability of Intercept/Detection (LPI/D) and has built in Transmission Security (TRANSEC) with Over-The-Air-Rekeying (OTAR) capability. It has the capability to interface and control certain aspects of the satellite such as resource control and antenna pointing. The SMART-T must be initialized with TRANSEC fill data and mission specific data. SMART-T does not provide COMSEC, but accepts data encrypted by the user. Selected SMART-Ts will have embedded FSEN switches. The SMART-T is interoperable with MILSTAR, FLTSAT EHF Packages (FEP), and EHF Packages on UHF Follow-On (UFO) Satellites.
