Commtact Develops Advanced Wireless Data Links for Unmanned Systems

Published: 18 Feb 2019 | Author: Mike Rees

Commtact, a leading developer of innovative wireless communications and information systems for both military and commercial applications, has partnered with Unmanned Systems Technology (“UST”) to demonstrate their expertise in this field. The ‘Silver’ profile highlights how their data link systems can be used for critical communications in tactical unmanned systems such as unmanned aerial vehicles (UAVs, UAS, drones, RPAS), unmanned ground vehicles (UGVs) and unmanned surface vehicles (USVs).

Mini Micro Wireless Data Link for DronesThe Mini Micro Data Link System (M2DLS) is an advanced digital data link system weighing just 100 grams and specifically designed for miniature and micro-sized UAVs and other unmanned platforms with strict SWaP constraints.

It provides full duplex digital communication, using Gaussian-shaped Minimum Shift Keying (GMSK) digital modulation to reduce power consumption. It can downlink real-time video images, LAN and serial data, and information from a wide range of sensors, with a range of up to 40 km, and provides superior reliability and performance even under the harshest of conditions.

The Advanced Mini Link System (AMLS) is an advanced digital data link system designed for mini UAVs and smaller sized tactical UAS as well as UGVs. With a weight of just 300 grams, it is ideal for such platforms with more stringent SWaP requirements.

It features an open architecture system that enables full duplex wideband, error correction techniques and high-rate communication, with the ability to downlink real-time video images, LAN and serial data, and information from a wide range of sensors. With high spectral efficiency and data rate selectivity, the system allows for multiple unmanned aircraft operating in the same airspace vicinity.

IDLS MK-II Integrated Wireless Data Link for UAVThe Integrated Data Link System (IDLS MK-II) is a digital data link system designed for medium and high altitude long endurance (MALE & HALE) unmanned aerial systems. Leveraging an open architecture design, it enables full duplex wideband, error correction techniques and high-rate communication in the Uplink (UPL) and Downlink (DNL) channels.

The IDLS-MK II provides secured communication between an unmanned platform and a Ground Data Terminal (GDT), which can be operated as a stand-alone unit or installed on a vehicle or roof. It weighs 2.5 kg and provides an operational range of up to 250 km, making it ideal for long-range UAV missions such as search & rescue, ISR and utilities inspection.

The UHF/VHF Radio (UVR) is an advanced analog/digital data link system that provides full-duplex audio and Ethernet data transmissions for a wide variety of unmanned platforms, including UAS, UGVs and USVs.

The UVR’s transceiver enables secure voice or data communication, including VoIP and air traffic control (ATC) comms, over both VHF and UHF frequency bands, supporting a range from 30MHz to 512MHz. The system has an operational range of up to 250 km, making it ideal for surveillance, search and rescue, and ISR missions. Maritime applications include ship-to-ship and ship-to-shore communications as well as manned-unmanned teaming.

Compact Wireless UHF Secondary Drone Data LinkThe Secondary Link is an advanced long-range half-duplex digital data link system that weighs just 60 grams, making it ideal for a broad range of unmanned platforms including small quadcopters and other multirotor UAS. It features simplex narrowband digital functionality and low-rate communication via UHF.

With a range of up to 250 km, the Secondary Link provides a single communication channel for commands to the unmanned vehicle and can also act as a primary link, as a redundant link for backup purposes or as a flight termination system (FTS).
