Zombie Satellites – Should We Fear the Graveyard Orbit of Un-dead Satellites?

If you’re prepared for ghosts, ghouls and goblins this Halloween, you might want to also consider zombies…satellites that is. Deep in outer space, where machines orbit the Earth, they share the sky with the un-dead. Can these historic satellites come back to life? HOW DO SATELLITES DIE? After a satellite completes its useful life and […]

via HACKADAY: Accidental Satellite Hijacks Can Rebroadcast Cell Towers

A lot of us will use satellite communications without thinking much about the satellite itself. It’s tempting to imagine that up there in orbit is a communications hub and distribution node of breathtaking complexity and ingenuity, but it might come as a surprise to some people that most communications satellites are simple transponders. They listen […]

via HACKADAY: Satellite Tracking With Friends

If you’re in the mood to track satellites, it’s a relatively simple task to look up one of a multitude of websites that can give you a list of satellites visible from your location. However, if you’re interested in using satellites to communicate with far-flung friends, you might be interested in this multi-point satellite tracker. […]

Oklahoma Radio Amateur is First to Score Satellite VUCC from Greenland

It took just 4 days — some of that time without much sleep — but ARRL member Gabe Zeifman, NJ7H/VE6NJH, of Oklahoma City recently became the first radio amateur to earn VUCC — working 100 grid squares — by satellite from Greenland. In fact, his is the first VUCC award of any kind from Greenland. […]

via HACKADAY: Old Rabbit Ears Optimized for Weather Satellite Downlink

Communicating with a satellite seems like something that should take a lot of equipment. A fancy antenna and racks full of receivers, filters, and amplifiers would seem to be the entry-level suite of gear. But listening to a weather satellite with an old pair of rabbit ears and an SDR dongle? That’s a thing too. […]

Virginia Engineering Students Tackle Satellite, Ground Station Projects

The University of Virginia (UVA) reports that some of its engineering students are among those at other Commonwealth schools working on Amateur Radio satellites and matching ground stations to track them and collect data. UVA said its student-built satellite is set to go into space late next year aboard an International Space Station resupply vehicle […]

via HACKADAY: See Satellites with a Simple Radio Telescope

Have you got a spare Dish Network antenna lying about? They’re not too hard to come by, either curbside on bulk waste day or perhaps even on Freecycle. If you can lay hands on one, you might want to try this fun radio telescope build. Now, don’t expect much from [Justin]’s minimalist build. After all, […]

Grote Reber Listens to Space: Out Of This World Hobbies at Eco Relics (Florida)

January is national hobby month, a time to acknowledge our interests that fall outside of our professions. Hobbyists and amateurs have reached the highest levels of human creativity, from backyard astronomers and garage chemists to Sunday painters and midnight scrawlers. Consider Grote Reber, for instance, an American original born in Wheaton, Illinois, in 1911. When […]

via HACKADAY: Junkyard Dish Mount Tracks Weather Satellites

There’s a magnificent constellation of spacecraft in orbit around Earth right now, many sending useful data back down to the surface in the clear, ready to be exploited. Trouble is, it often takes specialized equipment that can be a real budget buster. But with a well-stocked scrap bin, a few strategic eBay purchases, and a […]

SpaceX Wants FCC Approval to Launch a Gigantic Satellite Internet Network

An orbiting digital communications array that would eventually consist of 4,425 satellites. Private rocket launch service SpaceX is requesting government approval to operate a massive satellite network that would provide high-speed, global internet coverage, according to newly filed documents with the U.S. Federal Communications Commission. The California-based company, owned and operated by technology entrepreneur Elon […]

via HACKADAY: Listening to Jupiter on a DIY Radio

If you want to get started with radio astronomy, Jupiter is one of the easiest celestial objects to hear from Earth. [Vasily Ivanenko] wanted to listen, and decided to build a modular radio receiver for the task. So far he’s written up six of the eight planned blog posts. The system uses an LNA, a […]

via the ARRL: Indian Institute of Technology-Bombay Set to Launch Pratham Satellite

The Pratham satellite, built by students at the Indian Institute of Technology-Bombay, is expected to launch on September 26 onboard the Indian PSLV-C35 mission. Pratham, a 300 × 300 × 300 millimeter satellite with a mass of 10 kilograms, aims to measure total electron count at an 800 kilometer (approximately 500 mile) altitude sun-synchronous orbit. […]
