Realtime Enhancing Ltd Tests AI for Spacecraft Using Experience from Underwater Research
Cyprus-based company Realtime Enhancing Ltd announces the start of a series of trials for innovative artificial intelligence models designed for deployment on spacecraft. The new development leverages the team’s unique experience in creating and operating AI systems for autonomous underwater vehicles, which have been successfully used in scientific expeditions.
“We are adapting our proven algorithms for use in space,” comments the project’s lead engineer. “In underwater robotics, autonomy and the ability to quickly respond to environmental changes are critical. Now, we are applying these principles to orbit, where satellites face similar challenges: limited communications, complex conditions, and the need to make decisions instantly.”
During the trials, the company’s specialists are testing the AI’s capabilities in autonomous orientation, image processing, object detection, and real-time analysis of the space environment. This will increase satellite autonomy, reduce reliance on ground control centers, and expand the range of tasks that can be performed—from monitoring space debris to automatic instrument calibration and anomaly detection in data.
Company founder Leonid Gavrilov emphasizes:
“Our experience in underwater research is not just knowledge, but a special approach to creating reliable, self-sufficient systems. Space and the ocean are two environments where you cannot rely solely on external control. We are confident that our technologies will help make space missions more efficient, safer, and autonomous. This is a new stage in the development of both our company and the entire space technology industry.”
Latest news on the Chinese Star Compute program (briefly):
On May 14, 2025, China launched the first 12 satellites of the Star Compute project—an orbital network of supercomputers with AI models and laser communications. The project is being developed jointly by the startup ADA Space and Zhejiang Lab. The satellites are equipped with powerful processors, large memory, and the ability to perform complex calculations directly in orbit, solving the problem of limited communication bandwidth.
China plans to deploy a network of up to 2,800 satellites with a computing power of up to 1,000 peta-operations per second. The project is positioned as part of the national strategy and supports the country’s ambitions to achieve global leadership in AI by 2030.
Realtime Enhancing Ltd continues to test its solutions, focusing on international trends and collaborating with leading scientific centers to develop next-generation universal AI modules.

Project Overview
"BOGEX" startup presents a unique, lightweight, floating cable with 5km 5kW resonant control sensors. The system features fiber optic security, perimeter temperature and gas sensors, remote carrier frequency adjustment, and energy source connection. It uses a lightweight, non-metallic composite cable system with a core conductor, allowing for intermediate consumers with attachable lens-hermetic connectors. Power module 380 inverter on batteries is also included.

Progress
Advancements in wide bandgap semiconductor technology, such as silicon carbide (SiC), enable the increase in the operating frequency of high-voltage (HV) and generators using a series of devices connected to the same nominal voltage RF generators. These generators are often equipped with HV multipliers like the Cockcroft-Walton cascade, resonant inverter, and high-voltage transformer. High-frequency energy conversion typically reduces system size and cost and increases efficiency.

Electrical Characteristics
Our model integrates key features of a classic coaxial cable including 75 +/- 3.5 Ohm wave resistance, 55 pF/m cable electric capacity, 1.22 wave length shortening coefficient, 15 mOhm/m connection resistance, and 82% wave propagation speed. Skin layer thickness for 60Hz is 8.5 mm, while it's only 0.02 mm for 10 MHz current.

Innovation and Improvements
Our team has developed a computer model of RF transmission theory, managed by a non-removable, patent-protected program algorithm. This software is accompanied by our durable hardware – a protective iron box and transfer coil.

Plans for Enhancement
While we strive for modularity and compactness, there are areas of improvement such as extending the cable length (to 1250m), minimizing dimensions, simplifying the schema without resonance, exploring the reliability and efficiency of resonance, and investigating new cable solutions (capacity, resistance) and materials.

Patent & Documentation
Several patents have been filed, including a control resonance block and a duplicated channel block. We provide a product passport, accompanying documents, transformer parameters, and all agreements as outlined in the contract.

System Configuration
Current configuration includes:

220V isolation block
5kW power output over 5km distance
Performance with a coil or 380V generator with inverter (battery operation is possible)
Automated cutoff switch
Battery power in case of receiver failure
Twisted pair of wires and multi-strands without coaxial on a 1250-meter test
Frequency range switch for the cable
Connection of diode lamps
We are continuously seeking better solutions to ensure our BOGEX blocks for energy transmission and reception remain cutting edge in the industry. The way forward involves continuous optimization and fine-tuning to achieve the ideal functionality of the system.

Engineering Report: Development of a New TVC Block for Coaxial Cable Transmission System

Our engineering team is pleased to report the successful development and implementation of a new Transmitter-Receiver Converter (TVC) block designed for our coaxial cable transmission system.

Technical Highlights:

TL494 Chip Usage: One of our primary innovations is the utilization of the TL494 microchip as a modulator. The chip has an input 4, which allows a sinusoidal input with a maximum amplitude of 2.4V, resulting in Pulse Width Modulation (PWM) output. However, based on our latest evaluations, this feature might not be utilized in future iterations.

Pump Module Installation: We discussed the possibility of installing a pump module inside the coil, which would offer certain advantages in terms of space and operational efficiency. However, these benefits need to be further evaluated.

Cable Assemblies: The coaxial cables are coated with a calculated "skin layer" and are designed to be floatable. These enhancements are made possible due to the latest nanomaterials and advanced cable coating machinery.

Last Mile Connectivity: The system is designed to provide robust last-mile connectivity with the use of a thin wire via grounding galvanic protection of up to 2 kilowatts and data transmission capabilities. This makes the system particularly useful for agriculture ROV applications, with a range of 1-5 km.

Challenges and Considerations:

As with any innovative development, we have encountered several challenges. The certification of the successor institute's Mechanization and obligations to third parties posed initial obstacles. Other challenges include testing on a regular 450-meter coaxial, transformer specifications, non-conductance of tests in the presence of the Customer, and article publications not associated with the Customer.

Additionally, issues such as the complexity of the design, probable use of thyristor transistors, non-resonant current, radiation, induction, size, and assembly quality were noted and are currently being addressed. We also acknowledge the need to reduce the device's dimensions while maintaining a high-quality build.

Next Steps:

Our focus now shifts to further optimization of the TVC block. We are evaluating alternative signal forms, such as sine waves or approximations, to reduce emitted harmonic levels. Another focus area is enhancing the efficiency of the receiving part, specifically the input bridge.

Our engineering team is devoted to refining this design, addressing existing concerns, and improving upon the already substantial gains made thus far. We look forward to the future enhancements of our coaxial cable transmission system.

For any further questions or discussions, please contact our lead engineer
