Resumo | CubeSats are ideal transponder carriers to integrate a new GNSS-free geo-referencing system. The system concept might be viewed as an in-verted GPS configuration, utilizing four groundbased reference sta-tions and a number of repeaters in space. A time signal transmitted by one of the reference bases is retransmitted by transponders in space, re-ceived back at the bases, producing four ranging measurements for each satellite. The measurements are corrected for time delays in every time coded retransmission caused by three main sources: the transit time at the transponders, the path delays, and delays at the ground-based trans-mitter and receivers antennas, cables and electronics. An algorithm compares the repeaters positions for at least two groups of three refer-ence bases, minimizing unknown signal delays, providing the accurate position for each repeater. Once the repeaters coordinates are known, the other determinations and applications become straightforward. It is demonstrated by simulations, based on the system performance algo-rithms, that with a formation of at least four repeaters, the position of a remote target is determined for a single coded time signal transmission. A formation of multiple CubeSats in low earth orbits (LEO) is particular-ly suitable to accomplish the new georeferencing system. Simulations are presented, exhibiting accuracies which may become comparable to other space-based systems. This system has various strategic and eco-nomic applications in remote clock synchronism, navigation and target geo-positioning. It may be used as a backup to GNSS location systems in critical applications, or when such systems are not available. |
