First place in the Hackaday Prize was awarded today to “SatNOGS,” a project aiming to spin up a worldwide network of satellite ground stations—hence the project’s name, which is an abbreviation of “Satellite Network Of Ground Stations.” Its creators will receive either one paid ride into space, when such a ticket becomes available, or $196,418 (whose odd numeric value some astute readers may recognize as being a Fibonacci number).

The SatNOGS team edged out four other contenders in the final round of judging. Second place went to ChipWhisperer (a platform for security testing of embedded systems), third to PortableSDR (a compact software-defined radio), fourth to the Open Source Science Tricorder (a gadget for sensing various environmental parameters), and fifth to ramanPi (a Raman spectrometer based on the Raspberry Pi).

The SatNOGS project aims to serve enthusiasts who like to listen in to transmissions from the many satellites zipping around Earth in low or medium orbits. You can’t, of course, do that with a dish bolted to the side of your house. To do this right, you need a radio coupled to a high-gain antenna that can remain pointed in the right direction as the satellite of interest passes overhead.

The open-source design for such a DIY ground station is the main component of the SatNOGS project. But the project also includes facilities so that people from around the world can monitor satellites cooperatively. The idea is that  the ground stations will communicate with a central server on the internet. The server acts like a network manager, sending instructions to the ground stations and receiving digital copies of the signals they record. Assuming enough people build these ground stations, and that they have good geographic distribution, the system should allow much more comprehensive monitoring of satellite signals than anybody working in isolation could manage.

So congratulations to the SatNOGS team. Not that they need my advice, but I’ll give it anyway: Take the money.

Economics Drives Ray-Gun Resurgence

Laser weapons, cheaper by the shot, should work well against drones and cruise missiles

In an artist’s rendering, a truck is shown with five sets of wheels—two sets for the cab, the rest for the trailer—and a box on the top of the trailer, from which a red ray is projected on an angle, upward, ending in the silhouette of an airplane, which is being destroyed

Lockheed Martin's laser packs up to 300 kilowatts—enough to fry a drone or a plane.

The technical challenge of missile defense has been compared with that of hitting a bullet with a bullet. Then there is the still tougher economic challenge of using an expensive interceptor to kill a cheaper target—like hitting a lead bullet with a golden one.

Maybe trouble and money could be saved by shooting down such targets with a laser. Once the system was designed, built, and paid for, the cost per shot would be low. Such considerations led planners at the Pentagon to seek a solution from Lockheed Martin, which has just delivered a 300-kilowatt laser to the U.S. Army. The new weapon combines the output of a large bundle of fiber lasers of varying frequencies to form a single beam of white light. This laser has been undergoing tests in the lab, and it should see its first field trials sometime in 2023. General Atomics, a military contractor in San Diego, is also developing a laser of this power for the Army based on what’s known as the distributed-gain design, which has a single aperture.
