TASMUS is built on the principle that information superiority is as decisive as firepower in modern warfare. The system establishes a secure, high-capacity, and resilient communication infrastructure between maneuver units in the field and higher-echelon command centers. By enabling real-time data exchange from sensors, weapon systems, and command posts, TASMUS significantly shortens the decision-making and reaction cycle.

Operational Purpose and Role

The primary mission of TASMUS is to ensure uninterrupted, secure, and high-bandwidth communication between tactical units and operational/strategic headquarters. It enables:

• Brigade, battalion, and company-level command networks
• Real-time operational picture sharing
• Sensor-to-shooter connectivity
• Secure coordination across dispersed maneuver units

In this sense, TASMUS acts as the digital nervous system of land forces.

Doctrine and Concept of Use

TASMUS is designed primarily for land forces but is compatible with joint and combined operations. Its concept of operation supports:

• Network-centric warfare
• Highly mobile force structures
• Distributed command posts
• Electronic warfare-contested environments

The system ensures communication continuity even when units are on the move in dynamic combat scenarios.

System Architecture

TASMUS consists of three major subsystems:

Wide Area Subsystem

Provides long-range backbone connectivity through high-capacity radio links, IP routers, and cryptographic devices.

Mobile Subsystem

Vehicle-mounted communication nodes that maintain network access while maneuvering.

Local Area Subsystem

Establishes LAN infrastructure within command posts, integrating user terminals, servers, and tactical software systems.

With TASMUS-II, the architecture became fully IP-based, capable of routing both IPv4 and IPv6 traffic. Voice, data, and video share the same backbone with intelligent prioritization mechanisms.

Integration with Sensors and Weapon Systems

Although TASMUS is not a weapon system, it enables seamless integration between:

• Ground-based radar systems
• UAV ground control stations
• Artillery fire control systems
• Tactical command and control software
• Software-defined radios

This integration allows rapid transmission of targeting data from sensors to firing units within seconds.

Electronic Warfare Resilience

Modern battlefields are heavily contested in the electromagnetic spectrum. TASMUS incorporates:

• Frequency hopping
• OFDM-based transmission
• MIMO technology
• Encrypted communication
• Redundant routing and automatic path switching

These features allow operation under electronic protection measures. Detailed technical parameters regarding ECCM performance are not publicly disclosed.

GRC-5220 Tactical IP Radiolink

The GRC-5220 tactical IP radiolink device, integrated within TASMUS, provides:

• OFDM-based transmission
• Frequency hopping capability
• MIMO support
• Up to 200 Mbps Ethernet data rate
• Communication range exceeding 100 km under suitable RF conditions

Actual performance depends on terrain, spectrum conditions, and configuration.

Traffic Management and Prioritization

TASMUS dynamically prioritizes traffic types. Critical operational data such as fire support coordinates receive higher priority than administrative or non-critical data. In case of network disruption, the system automatically reroutes traffic via alternative paths.

Information Security and Cryptography

Voice, data, and video communications are protected by cryptographic devices. The system supports remote cryptographic key management through ASELSAN’s Key Management System. Specific cryptographic algorithms and security classifications are not publicly disclosed.

Frequently Asked Questions

What is TASMUS used for?

• TASMUS provides secure, high-capacity communication between tactical units and command centers. It forms the backbone of digital command and control infrastructure.

What is the difference between TASMUS and TASMUS-II?

• TASMUS-II features a fully IP-based architecture with IPv6 support, higher bandwidth capacity, and advanced routing capabilities.

What is the maximum range?

• With the GRC-5220 radiolink, communication exceeding 100 km is possible under suitable RF conditions. Actual range depends on terrain and configuration.

Is it resistant to electronic warfare?

• Yes. It incorporates frequency hopping, OFDM, MIMO, encryption, and alternative routing mechanisms to operate in electronically contested environments.

Is TASMUS a weapon system?

• No. It is a communication infrastructure that connects sensors, weapons, and command systems.

How many targets can it track simultaneously?

• Target tracking capability depends on integrated radar and sensor systems. TASMUS transmits the data but does not perform target tracking itself.

Is it mobile or fixed?

• Both configurations are available. It can be deployed on vehicles or installed in shelter-based command centers.

What are its equivalents?

• Comparable systems include NATO tactical communication networks and U.S./European IP-based tactical battlefield communication infrastructures. TASMUS offers the advantage of nationally developed cryptographic and integration capabilities.
