TerraARX, AquaARX, HeliARX: a guide to CTech’s ARX range

Quick answer: CTech’s ARX family extends beyond the air-focused SkyARX into a satellite-communications-on-the-move (SATCOM) range covering land, naval and helicopter platforms. TerraARX was developed for armoured vehicles and land platforms, AquaARX for manned and unmanned naval vessels, and HeliARX for helicopters. TrackARX is a compact tracking and communication device that switches automatically between satellite and cellular networks, while QuARX is a high-speed SATCOM modem supporting the C, X, Ku and Ka bands. The SCOFUS technology merges all of these channels into a single broadband connection.
TerraARX and AquaARX: the land and sea legs
TerraARX gives land vehicles on border security, patrol and ISR missions satellite connectivity on the move; the official page mentions data rates of up to 20 Mbps and highlights easy installation on armoured vehicles. The company announced in 2023 that TerraARX was ready for use. AquaARX carries the same architecture into maritime conditions: two configurations with 12 and 20 inch reflectors, Ku and Ka bands, an EIRP range of 44-54 dBW, a DVB-S2 modem and AES-256 encryption. The company counts command-and-control and imagery relay for unmanned surface vehicles among its use cases.

HeliARX: SATCOM under the rotor
The main challenge for satellite communications on helicopters is that the turning rotor blades keep interrupting the signal. According to the official page, HeliARX overcomes this with a signal transmission technique that removes the rotor effect and a blockage-tolerant CTech waveform. Operating in the Ku band, the system offers a 50 W BUC, 43.4 dBW EIRP and data rates of up to 40 Mbps; the modem uses AES-256 encryption and the antenna unit is IP66 protected. The system was qualified to MIL-STD-810H, MIL-STD-704F, MIL-STD-461E and DO-160G. Search and rescue, disaster response and border security are among its application areas.

TrackARX and QuARX
| Feature | TrackARX | QuARX |
|---|---|---|
| Mission | Voice, messaging and position tracking; uninterrupted connectivity | High-speed broadband SATCOM |

TrackARX was unveiled at the Defence in Space event in London in September 2024. The device switches automatically between satellite and cellular networks where coverage weakens, aiming to keep teams continuously connected.
SCOFUS: the layer that merges the channels
SCOFUS is a network technology that combines different communication channels — SATCOM, an RF line-of-sight link, LTE/5G (private APN), WiFi and wired Ethernet — into one broadband channel. The system distributes data packets across the channels according to bandwidth and latency parameters; when one channel drops, communication continues without interruption. According to the official page, up to 10 channels of high-quality video plus telemetry and autonomous control data can be carried simultaneously, with the whole structure monitored through the MOBIoT management software. This layer can bring the SkyARX and UfukLink systems together in a single network; the modem side heading to NATO is covered in the SecureARX file.
