Recently the 29.8 meter parabolic antenna at the Australian OTC (overseas telecommunications commission) station came back to life again after nearly forty years spent in decommissioning limbo. This parabolic dish …read more Continue reading Carnarvon’s Decommissioned NASA Satellite Dish Back In Service After 40 Years
A recent writeup by Tom Nardi about using the 6502-based NES to track satellites brought back memories of my senior project at Georgia Tech back in the early 80s. At our club station W4AQL, I had become interested in Amateur Radio satellites. It was quite a thrill to hear your …read more
On the 30th August 2019, the President of the United States tweeted an image of an Iranian spaceport, making note of the recent failed Safir launch at the site. The release of such an image prompted raised eyebrows, given the high resolution of the image, and that it appeared to …read more

Here’s an interesting thought: it’s possible to build a cubesat for perhaps ten thousand dollars, and hitch a ride on a launch for free thanks to a NASA outreach program. Tracking that satellite along its entire orbit would require dozens or hundreds of ground stations, all equipped with antennas and a connection to the Internet. Getting your data down from a cubesat actually costs more than building a satellite.
This is the observation someone at Amazon must have made. They’ve developed the AWS Ground Station, a system designed to downlink data from cubesats and other satellites across an entire orbit. …read more

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.
[Stephen Downward VA1QLE] developed the tracker to make it easier to figure out which satellites would be simultaneously visible to people at different locations on the Earth’s surface. This is useful for amateur radio, as signals can be passed through satellites with ham gear onboard …read more
The things Hackaday readers come up with and post over on Hackaday.io never cease to amaze us. If you’ve never checked it out, be careful — you can easily spend hours (or weeks) of your life just skimming through the projects that have been logged there. Many of the builds use modern development tools like Arduino and Raspberry Pi, but every so often we come across a project that takes a more difficult road.
That’s the case with [Keplermatik’s] Cold War-era satellite-tracking project, also aptly named Keplermatik. This a build that’s still in progress, which just means you’ve got the …read more
