ARISS Slow Scan TV (SSTV) Transmissions: A Unique Opportunity for Amateur Radio Operators and Space Enthusiasts
Amateur Radio on the International Space Station (ARISS) has been delighting ham radio operators and space enthusiasts with Slow Scan TV (SSTV) transmissions since 2014. These transmissions offer a unique opportunity to receive images from space, showcasing the fascinating world of amateur radio in space exploration.
What is ARISS SSTV?
ARISS SSTV is a project that transmits images from the International Space Station (ISS) using Slow Scan TV technology. SSTV is a technique that converts images into audio signals, which are then transmitted over radio frequencies. These signals can be received and decoded by amateur radio operators and enthusiasts worldwide.
