SMALL SIZE, BIG MISSION: ASTRA SATELLITES AND THE CUBESAT ERA IN THE SPACE ECONOMY
Space is no longer just the playground of massive government agencies; it has become the arena for innovative companies and compact technologies. While the giant Astra satellites have carried the weight of European broadcasting for decades, they are now being joined by the new darlings of the space economy: CubeSats. How do these shoebox-sized satellites influence our broadcasting and how do they function?
1. Hardware and Structure: What is a CubeSat?
While a traditional Astra satellite is the size of a bus, CubeSats are composed of units (1U) measuring just $10 \times 10 \times 10$ cm.
- Physical Deployment: These satellites are launched as “auxiliary payloads” in the extra space of rockets. They feature miniaturized propulsion systems, deployable solar panels, and high-frequency transceivers.
- LNB Compatibility: Most CubeSats operate in Low Earth Orbit (LEO), whereas Astra satellites reside in Geostationary Orbit (GEO). New-generation ground stations use hybrid LNB systems capable of processing data from both altitudes.
2. Software Installation: Data Rates and Frequency Management
The biggest advantage of CubeSats is their use of Software Defined Radio (SDR) technology.
- Interface Access: Ground station operators connect to these satellites via encrypted terminals using specific IP addresses and secure ports.
- Channel Scanning: To track CubeSat data transmitted through the Astra infrastructure, your receiver must support DVB-S2X modulation. This allows for high-speed data throughput even in very narrow bandwidths.
3. Post-Installation: The New Era of Space Economy
These satellites offer more than just TV broadcasting; they provide connectivity for the Internet of Things (IoT), agricultural observation, and real-time meteorological data.
- Performance Testing: Because LEO satellites move quickly across the sky, “Tracking Antenna” systems are required for stability.
- Cost Efficiency: Development costs are up to 90% lower than traditional satellites, signaling a future where global internet and broadcasting services are significantly more affordable.
