SYSTEMS AND METHODS FOR USING DECOMPILED OR DESTRUCTIVE SPACE (SPACE DEBRIS) SATELLITES AS PASSIVE OR ACTIVE SIGNAL RELAYS IN RF-BASED SPACE COMMUNICATION SYSTEMS.

Abstract

This invention focuses on the use of defunct (orbital space debris) satellites as passive or integrated passive module signal relays in RF (radio frequency) based space communication systems. A signal sent from a mobile RF transmitter system is transmitted to the first defunct satellite; via the reflective surface or passive RF relay module on the satellite body, the signal is transferred to the next satellite or the final destination. The developed mathematical model and dynamic reach maps facilitate mission planning by pre-calculating the total signal losses and reach distance in the system. This method enables long-distance, reliable communication with low-power space robots and allows for the repurposing of existing space debris into a sustainable communication infrastructure.

Description

1 TARIFF In RF-based space communication systems, its function is... COMPLETE OR DECAYED SPACE (DEBRIS) SATELLITES WHETHER IT IS USED AS A PASSIVE OR ACTIVE SIGNAL RELAY RELATED SYSTEM AND METHOD Technical Area 5 The invention has implications for the fields of space technologies, communications engineering, and RF (radio frequency) systems. It is used especially in low-power robotic systems, satellites, or long-range mobile vehicles. It is used as range extender infrastructure in communications. State of the Art In current technology, RF communication is either direct signal transmission or active satellite relays. 10 Communication is provided via these satellites. However, defunct satellites have not been used for communication until today. It could not be evaluated within the infrastructure. This situation results in a large number of idle satellites in orbit. Despite its existence, this leads to limited communication infrastructure. Purpose of the Invention • Extending the range of RF signals, 15 • Re-evaluating and repurposing defunct satellites, • Providing a low-cost communication infrastructure for small-scale robotic tasks, • Contributing to the transformation of space debris into sustainable infrastructure. Explanation of the Figures 1.

It emits a low-power RF signal (2) toward the target station. This signal is sent to the first junk satellite (3) 30 It reaches the reflective surface (3a) or passive relay module (5a) on the satellite, where the signal is lost. It is minimized and directed to the next satellite (4). The same process is done for the second satellite (4a) and other The same applies to satellites. Each relay ring provides an average range increase of 500–1,000 km. This is ensured. The transmission chain continues until the final destination or next mission point. The mathematical model developed includes: free space loss, reflection loss, 35 per module. 2 By calculating relay loss and additional losses due to the space environment, the total signal loss can be estimated in advance by 5. It determines and transmits it to the control center. This is valid for reverse transmission. How the invention can be applied to industry. This system can be integrated with existing RF module technologies and CubeSat platforms. Passive Alternatively, it can be powered by low-power modules, solar panels, and thermoelectric generators. Dynamic access maps are used for task planning and route optimization in the control center. It can be used in applications such as space exploration vehicles, autonomous robotics systems, and military communications. It finds widespread use, particularly in networks.
