GDT – Data Transmission Terminal
Smart connection between RP and GCS. Accuracy, stability, and range for critical missions.
The GDT is the terminal responsible for creating the point-to-point communication link between the ARP and the GCS. It ensures the secure and continuous exchange of commands, telemetry, and payload data throughout the mission.
Equipped with a high-gain directional antenna and automatic pointing, the GDT tracks the aircraft in azimuth and elevation with high precision.
To operate, there only needs to be a line of sight (LOS) between the terminal and the ARP.
High-performance architecture
Designed for demanding missions, the GDT integrates navigation modules, sensors, actuators, and processors dedicated to pointing and link stability.
Key technologies
01.
Precise navigation
The GDT operates with two GNSS receivers in moving base and hover.
The combination of the two allows for the determination of three-dimensional position and exact direction for antenna pointing.
This ensures faster and more reliable pointing, even in scenarios with terrain variations.
02.
Intelligent pointing controller
The controller performs azimuth and elevation calculations azimuth and elevation, filters GNSS data, and coordinates the entire mechanical system and the datalink.
This ensures stability even over long distances or sudden changes in the ARP's trajectory.
03.
Robust actuation system
High torque stepper motors with digital drivers ensure smooth and precise movements, maintaining performance even with wind or vibration.
04.
Field structure
The mechanics of the GDT are reinforced for outdoor operation:
Weather protection
Integrated cables without exposure
Safe rotation and locking
Long-term durability
05.
Secure and stable data link
The GDT uses a point-to-point datalink with:
Interference mitigation
Low latency
Advanced media access control
128-bit AES encryption
Benefit: reliable communication for mission-critical tasks.
06.
One antenna, two functions
High torque stepper motors with digital drivers ensure smooth and precise movements, maintaining performance even with wind or vibration.
Narrow beam + high gain, aligned with the pointing system.
XRTK wireless connection, isolated to prevent interference.
07.
RF cables prepared for movement
The cables are assembled to reduce noise, impedance variation, and mechanical deformation, ensuring total signal integrity during pointing.
Real-time monitoring with SNMP
GCS has direct access to the GDT SNMP server, viewing essential indicators:
- RSSI (signal strength)
- SNR (signal-to-noise ratio)
- CCQ (link quality)
- supply voltage
- other operating parameters
Benefit: immediate diagnosis, anticipation of failures, and greater operational safety.
