Blockchain is a distributed ledger that records transactions securely, openly, and in a tamper-resistant manner across a network of computers. The data is kept in blocks, and a chain of blocks is created by connecting each block to the one before it using cryptographic hashes.
It has become a significant participant in numerous industries. Blockchain facilitates transparent and trustless transactions by functioning on a peer-to-peer network, as against traditional centralized systems where a single party owns the database.
Consensus mechanisms, such as Proof of Work (PoW) and Proof of Stake (PoS), guarantee the legitimacy of transactions and preserve the decentralized network’s integrity. These contracts automate and enforce the execution of predefined rules, opening up possibilities for a wide range of applications beyond simple value transfers.
In this article, we explore how blockchain technology can secure satellite communications.
Satellite Technology
Satellite technology has proved essential for modern communication, navigation, and remote sensing. Broadcasting, weather monitoring, military surveillance, and worldwide networking are all made possible by satellites in orbit around the Earth.
By serving as intermediaries in orbit, communication satellites enable information sharing between transceivers on the ground. These satellites pick up signals from a station that is positioned on Earth, amplify them, and then transmit the signals back to the target location on Earth.
Geostationary Earth Orbit (GEO), Low Earth Orbit (LEO), and Medium Earth Orbit (MEO) are the three most prevalent orbital classes for satellites. Satellites that are geostationary are perfect for broadcasting and communication since they are positioned at fixed points in relation to the Earth’s surface and can continuously cover a certain area.
LEO satellites, on the other hand, orbit at lower altitudes and are commonly used for Earth observation, remote sensing, and global positioning systems (GPS). MEO satellites are in between geostationary and LEO, and provide a compromise between latency and coverage.
