Savronik Satellite Ground Terminal: X and Ku band
Quick answer: The Savronik Satellite Ground Terminal (UYT) is a transportable ground station developed for military satellite communications, providing voice and data transmission in the X and Ku bands. According to the official product page, the terminal establishes a secure network where no line of sight exists; its trailer construction allows it to be deployed to different areas according to operational needs, and its remote control and command capability allows it to be run from a separate centre. The product family is completed by a software-defined radio (SDR) capable of transmitting up to 137 Mbps and the SavroLINK gateway that bridges different communications systems.
What does a satellite ground terminal do?
In environments such as mountainous terrain, an overseas mission or a disaster area where infrastructure has collapsed, a direct radio connection between two points, within line of sight, cannot be established. A satellite ground terminal overcomes that constraint by sending data up to a satellite and down to the opposite station. In military use, the X band is preferred for its state-allocated and comparatively jam-resistant character, while the Ku band offers capacity flexibility over commercial satellites. Savronik’s terminal supports both bands, making a switch to commercial capacity possible when military-allocated capacity is full or unreachable. In the company’s own words, the terminal is a product “developed and produced within the scope of military satellite communications”; the programme under which the development was carried out has not been disclosed.

Which satellites the terminal can reach, including any TÜRKSAT military payloads, has not been officially disclosed. Antenna pointing uses the company’s Antenna Control Unit, which performs precise two-axis tracking; the unit is described in the data link file. Because it can process messages arriving over serial and Ethernet interfaces and perform switching and filtering, the unit also forms part of the terminal’s remote command architecture.
Place in the operational concept
In a military SATCOM architecture, trailer-type terminals form the backbone between forward-deployed elements and the main command centre. In a typical scenario, reconnaissance elements communicate in the field over a mesh radio network; the imagery and data collected are relayed via the satellite ground terminal to a centre hundreds of kilometres away. The terminal’s remote command capability allows personnel to be positioned away from the antenna site, reducing the ground signature against the electronic attack threat. The trailer construction eases movement with standard tractor vehicles and allows the deployment site to be changed according to the operational plan; no fixed facility investment is required. Using more than one terminal on the same network allows continuity planning with primary and backup nodes. The antenna tracking experience Savronik gained from UAV data links is applied to the precise pointing of the satellite antenna through the Antenna Control Unit from the same product family.
SDR: the TESİD award-winning transceiver
The second product in the family, the High-Speed Software-Defined Radio, works in the L/S, C and Ku bands, carries out two-way data transmission of up to 137 Mbps and includes built-in video compression. Because the waveforms are defined in software, satellite communications, radio link and custom waveforms can be implemented on the same hardware; direct sequence and frequency-hopping spread spectrum (DSSS and FHSS) techniques are supported alongside optional AES-256 encryption. Spread spectrum makes detection and jamming harder by distributing the signal across a wide band, while the software-based architecture allows a new waveform to be loaded without changing hardware when the threat environment shifts. Savronik’s “Multi-Purpose Software-Defined Transceiver Unit” project won the Innovative Product Award in the large-company category at the 2023 TESİD Innovation and Creativity Awards.
SavroLINK: bridging different radios
In the operational field, HF radios, line-of-sight links, satellite terminals and IP-based devices work with different protocols. The Savronik Interoperability System (SavroLINK) is presented as a gateway architecture that provides voice and data transfer between those systems. It allows a mesh radio network to reach the main command centre over the satellite terminal, and an HF radio network to connect to an IP network; the existing radio inventory joins the common network without being replaced. The company’s communications portfolio as a whole is covered in the product guide.
