SMALL TACTICAL TERMINAL (STT)

KOR-24A

Link 16 and Secure VHF/UHF Line-of-Sight Networking at the Tactical Edge

The Small Tactical Terminal (STT) KOR-24A, co-developed by Viasat and L3Harris, is a two-channel radio designed to meet the needs of users who have size, weight and power constraints but need the information available on Link 16 networks and tactical VHF/UHF.

Tactical warfighters, including ground vehicles, helicopters, UAVs, small boats and light ISR aircraft, can now have simultaneous access to Link 16 and either wideband UHF or legacy VHF/UHF. This terminal is packaged in an affordable, industry-standard compact form factor and is ruggedized to meet demanding environmental requirements.

PRODUCT DESCRIPTION

The STT brings real-time situational awareness, location data and command and control (C2) to tactical gateways and edge warfighters. With this terminal, edge users have access to both air and ground (friendly and enemy) situation data and can provide secure and reliable target data to the network. With the UHF channel configured for S-TADIL J or JRE, users have a single terminal that provides both LOS and BLOS TADIL J connectivity.

The STT can be used to bridge the gap in user’s awareness between the air picture provided by TADIL J/Link 16 and the ground picture provided by other VHF/UHF data link formats. This two-channel radio dramatically reduces data latency and improves data integrity between traditional network platforms and users at the edge for both situational awareness and C2. Link 16 and combat net radio built-in identification means that STT terminals provide blue force reporting to reduce blue-on-blue engagements and avoid fratricide. With standardized TADIL messages and Ethernet interfaces, the STT can be used with multiple computers in a wide range of applications.

L3Harris is also the first Link 16 provider to integrate Concurrent Multinet (CMN) and Concurrent Contention Receive (CCR) advancements across its portfolio of Non- Developmental Items, providing warfighters with Concurrent Multiple Reception (CMR) capabilities for assured access to mission-critical information. These features, coupled with Link 16 Enhanced Throughput (ET) modes, will enable network planners to fully optimize network performance, allowing maximum participants sharing maximum capacity of information to support evolving mission requirements. The STT also implements the latest high assurance algorithms using a field proven programmable Cryptographic Modernization compliant engine to securely serve joint and coalition mission requirements, while maintaining backwards compatibility with legacy communications systems.
