Paperback. Condition: new. Paperback. Right now, hundreds of satellites are passing overhead-transmitting not voices, but data. Telemetry streams, digital images, IoT packets, and experimental protocols pour through the sky in formats most operators never learned to hear. While traditional ham radio still reaches for the ionosphere, a quiet revolution has already happened in orbit. The satellites speaking today are digital, software-defined, and increasingly sophisticated. The operators who understand them are building the future of amateur space communications. Everyone else is listening to static.This is the book that bridges the gap.Digital Satellites Decoded is the definitive technical guide for amateur radio operators, satellite enthusiasts, and communications engineers ready to master the digital systems transforming the amateur satellite service. Written with the depth of a professional reference and the clarity of patient instruction, it takes you from foundational concepts to operational mastery across nine comprehensive chapters.You will learn how software-defined radio dismantles the limitations of traditional hardware, enabling a single receiver to decode virtually any satellite signal through software alone. You will explore the full landscape of digital modulation-from the FSK and PSK variants carrying telemetry from university cubesats to the chirp spread spectrum of LoRa links and the turbo-coded waveforms approaching the Shannon limit. You will build practical skills for decoding real satellite data: extracting telemetry frames, interpreting engineering health data, monitoring spacecraft performance, and contributing to global observation networks like SatNOGS.The book delivers hands-on expertise for constructing next-generation ground stations. You will design modular, scalable, remotely operable systems integrating SDR transceivers, automated rotator control, Doppler correction, and complete digital signal processing pipelines. You will master the open-source toolchain-GNU Radio, gr-satellites, Gpredict, and the complete SatNOGS ecosystem-that has democratized satellite reception and turned individual operators into citizen scientists.For those pushing boundaries, the text examines emerging frontiers: cognitive radio for dynamic spectrum access, advanced forward error correction with LDPC codes, experimental modulation design, and even the optical communication systems that may define the next decade of amateur space links. Every concept is grounded in real missions, real signals, and real operational practice.Whether you are a licensed amateur seeking to expand beyond analog modes, a university student building your first cubesat ground station, an engineer evaluating satellite communication architectures, or simply a curious technologist who has watched satellites streak across the night sky and wondered what they were saying-this book gives you the language to understand them and the tools to join the conversation.The satellites are transmitting. The data is there for anyone with the knowledge to receive it. Build that knowledge. Build that station. Start decoding. This item is printed on demand. Shipping may be from our UK warehouse or from our Australian or US warehouses, depending on stock availability.…

Paperback. Condition: new. Paperback. Every time you work a satellite, you're not just making a contact-you're continuing a legacy that began when a beach-ball-sized satellite called OSCAR-1 whispered "Hi" from orbit in 1961. But what if that legacy didn't end in low Earth orbit? What if the next voice you heard from space came from the far side of the Moon, from a relay orbiting Mars, or from a laser beam crossing 100 million kilometers of void?The Hamsat Horizon is the definitive guide for amateur radio operators who refuse to accept that the horizon is the limit.This book takes you beyond geostationary orbit and into the realm that professionals once claimed was theirs alone: cislunar space, deep space, and the interplanetary frontier. You'll discover how delay-tolerant networking transforms impossible light-time delays into reliable data links. You'll learn why optical communication-laser links between worlds-isn't science fiction but the next spectrum frontier amateurs are already pioneering. You'll explore the engineering of lunar repeaters, the architecture of a Martian internet, and the citizen-science opportunities that let you participate in active Mars missions today-not decades from now.This isn't speculation. This is happening now.NASA's Artemis program is opening launch opportunities that amateurs can access. Commercial lunar landers are carrying payloads at costs unimaginable a decade ago. University CubeSat teams are proving that small satellites can survive the radiation and propulsion challenges of interplanetary travel. And a growing network of advanced amateur ground stations is already receiving signals from lunar orbiters and Mars probes-stations that could, within your operating lifetime, close the first two-way QSO with another planet.Inside, you'll find: The complete orbital mechanics and link budgets for Earth-Moon and Earth-Mars communication-explained clearly, calculated honestly, with no hand-waving about "future technology"How to build or upgrade your station for deep space: antennas, receivers, low-noise amplifiers, and tracking systems that rival professional Deep Space Network capabilities at amateur scaleThe regulatory roadmap for lunar and deep space amateur allocations-what the ITU says, what national administrations require, and how to navigate bothReal projects on real drawing boards: lunar repeaters, deep space CubeSats, optical LaserSats, and the distributed interplanetary relay network that could tie them all togetherThe open-source software, hardware designs, and collaborative platforms that let you contribute to missions without being a millionaire or a rocket scientistHow to recruit, mentor, and inspire the next generation of operators-because the repeater on Mars won't mean anything if there's no one left to call itThe amateur spirit has always been about doing what experts said couldn't be done. OSCAR-1 was impossible until it wasn't. Earth-Moon-Earth was impossible until hams proved otherwise. Geostationary amateur satellites were impossible until Es'hail-2 lit up the sky.The Moon is next. Mars is next. And the operator who makes that first interplanetary contact could be you.Whether you're a satellite veteran looking for the next challenge, an educator building a STEM program that genuinely excites students, or a dreamer who has always looked up and wondered "what if?"-The Hamsat Horizon gives you the knowledge, the roadmap, and the inspiration to stop wondering and start building.The horizon isn't the end of your range. It's the beginning.Pick up The Hamsat Horizon today. The future is calling-and it's not from Earth. This item is printed on demand.
