The Defence Electronics Applications Laboratory (DEAL) in Dehradun has made significant strides in airborne communication technology with the successful trials of the C-Band Line-of-Sight (LOS) Datalink under the Datalink Airborne Platforms (DLAP, DEA-118) project. These trials were conducted on the HS125-800 Hawker aircraft at the Centre for Airborne Systems (CABS) in Bengaluru, in collaboration with industry partners.
The trials started with ground-based tests between the Ground Earth Station (GES) and a moving vehicle, ensuring the reliability of the datalink system under dynamic conditions. The Line Replaceable Unit (LRU) for the airborne datalink was successfully installed on the HS125-800 Hawker aircraft, marking a significant step in integrating advanced communication systems into existing platforms.
A 1.8-meter Target Tracking and Control (TTC) system was evaluated for its performance. The system was tested in both RF (Radio Frequency) and GPS tracking modes, demonstrating robust tracking capabilities essential for military operations.
The project conducted three flight sorties to test the full functionality of the C-Band LOS Datalink. The system exhibited impeccable performance, achieving:
- Data Throughput: High data transfer rates were maintained, critical for real-time battlefield communication.
- Voice Communication: Full-duplex, error-free voice communication was established, ensuring clear and uninterrupted dialogue between airborne and ground units.
- Tracking: The system provided accurate tracking up to an aerial distance of 250 km in both GPS and RF modes, showcasing its potential for long-range operations.
The success of these trials underscores the capabilities of DEAL and its partners in enhancing India’s aerial communication infrastructure. This advancement in datalink technology not only boosts the operational efficiency of military aircraft but also supports a wide array of missions by providing secure, high-speed communication channels.
