Just ahead of the currently-in-progress Satellite 2018 show, COMSAT outlined their plans for the Thales MissionLINK terminal as an integral piece of the Department of Defense’s (DoD) network modernization architecture for vehicular and dis-mounted units in a Communications-On-The-Move (COTM) environment.
Iridium Certus user terminals sign onto the network via a gateway located in the U.S. where all data and voice traffic lands and is seamlessly handed off to terrestrial circuits. Depending on the user terminal’s location and average number of cross-linked satellite hops, the latency in any given connectivity session is as low as 100 milliseconds round trip, which is a substantial improvement when compared to geostationary systems. This opens Iridium Certus up to a range of latency dependent enterprise applications like video conferencing and secure voice calls.
Leveraging Thales’ pedigree in “tacsat” and data link comms systems, their Iridium Certus Thales MissionLINK terminal enables the capability to create network level system interfaces to a number of existing DoD standards, building a secure SATCOM node into vehicular and dismounted comms kits.
COMSAT points out that beyond network performance differentiators, Iridium Certus’ RF links present a very low probability of intercept due to rapid data path transition between multiple cross-linked satellites that make up the Iridium NEXT LEO constellation. This rapid path transition also presents strong benefits in terms of network resiliency as connections can be routed around any one satellite anomaly, something that simply isn’t feasible in a traditional geostationary or bent pipe network architecture.
