Watching the Watchers: The State of Space Surveillance

By now you’ve almost certainly heard about the recent release of a high-resolution satellite image showing the aftermath of Iran’s failed attempt to launch their Safir liquid fuel rocket. The geopolitical ramifications of Iran developing this type of ballistic missile technology is certainly a newsworthy story in its own right, …read more

Plasma-Powered Thrusters For Your Homebrew Satellite Needs

It seems as though every week we see something that clearly shows we’re living in the future. The components we routinely incorporate into our projects would have seemed like science fiction only a few short years ago, but now we buy them online and have them shipped to us for …read more

How to Build a CubeSat

There was a time when building your own satellite and having it placed into orbit would have been a wild dream. Now it is extremely possible, but still not trivial. A CubeSat is a very small satellite that can hitch a ride with a bigger satellite or get tossed out …read more

Full Earth Disc Images From GOES-17 Harvested By SDR

We’ve seen lots of hacks about capturing weather images from the satellites whizzing over our heads, but this nicely written how-to from [Eric Sorensen] takes a different approach. Rather than capturing images from polar satellites that pass overhead a few times a day, this article looks at capturing images from …read more

Es’hail-2: Hams Get Their First Geosynchronous Repeater

In the radio business, getting the high ground is key to covering as much territory from as few installations as possible. Anything that has a high profile, from a big municipal water tank to a roadside billboard to a remote hilltop, will likely be bristling with antennas, and different services …read more

Oops… Britain Launched A Satellite, But Who Remembers It?

Did you know Britain launched its first satellite after the program had already been given the axe? Me neither, until some stories of my dad’s involvement in aerospace efforts came out and I dug a little deeper into the story.

I grew up on a small farm with a workshop next to the house, that housed my dad’s blacksmith business. In front of the workshop was a yard with a greenhouse beyond it, along one edge of which there lay a long gas cylinder about a foot (300mm) in diameter. To us kids it looked like a torpedo, and I …read more

GPS III Launching Today But You Can’t Use it Until 2022

Imagine if you bought a new car but they keys were not going to be shipped to you until a few years later. That’s analogous to the situation the U.S. Air Force finds itself in. The first GPS III satellite is finally ready to launch today, December 18, 2018 — a little over 2 years beyond the original schedule. However, most of the unique GPS III features won’t be available until at least 2022, according to a 2017 Government Accounting Office (GAO) report to Congress.

GPS III is a project to launch 32 new satellites that will — for military …read more
