Specification

Tactical Software-Defined Radio for complex electromagnetic environments.

TACSDR is a TACtical Software-Defined Radio built for the modern tactical mission. Its software-defined architecture makes it the world’s first and only handheld used for communication, signal intelligence and spatial sensing purposes.

This specification is focused on TACSDR's communications capabilities

TACSDR delivers voice, video, and high-speed data in a compact, highly portable handheld platform. Using a Linux-processor and AllSeeing's software-defined radio architecture, it supports ad-hoc, self-forming, and adaptive networking for dismounted users on the move. Its software-driven design allows the system to be upgraded and reconfigured as mission requirements, waveforms, and communication needs evolve.

Why TACSDR

• Maintains connectivity in dynamic environments

• Supports voice, video and data in FM and MANET modes

• Support RF signal intelligence and RADAR sensing modes

• Integrates tactical visualization tools, remote management tools, APIs, built-in apps, and Linux tools

At a glance

• Frequency bands: 225–2600 MHz

• Output power up to 5W RF output

• Battery life: Up to 8 hours

• Programable to fit any needs

• Multi-unit synchronization using wireless signals

• Touchscreen with physical controls for field operation

Need for Tactical Connectivity

Modern tactical missions depend on sensors, software, data links, and real-time situational awareness, creating a need for radios that deliver fast, mobile communications in changing field environments. TACSDR rises to meet this mission need!

Need for Adaptable RF Systems

Evolving frequency, network, and data requirements demand adaptable RF systems, creating a need for flexible radios that can be upgraded, reconfigured, and tailored to different field mission profiles quickly. TACSDR provides a rugged, reconfigurable radio platform that adapts to changing mission needs without hardware redesign.
