Thank you to Carl Reinmann (aka usradioguy) for submitting his blog post which goes into deeper detail about the NOAA-15 weather satellite imaging failure that we posted about last week. Future tests will involve stronger target detections, and multiple targets. The gif below is a brief demonstration of the target tracker (with very weak data).

This is the code that will be able to track targets and plot them on a map, by using an array of passive radar surveillance antennas with the KrakenSDR. Our team continues to make steady progress on more advanced passive radar code as well. In the near future we will be uploading more demonstrations like this with multiple stations set up. Once the balloon falls to a lower altitude and the elevation from the antenna is less than 45 degrees accurate tracking resumes. At this angle the antenna array can no longer track the balloon correctly. One interesting thing to note is how the KrakenSDR tracks the balloon accurately, until the elevation angle between the antenna and balloon goes above 45 degrees which happens when the balloon rises higher and comes too close to the station. Once the weather improves we'll be setting up a distributed two-station test. The yellow dot indicates the actual GPS location of the weather balloon. Because it's only a single station, the red estimation dot can be ignored. The above is a video of a simple timelapse demo of the system tracking a weather balloon from a single station.

You can also do offline analysis of log files collected from the Android App or recorded via the Web GUI.Īs part of the testing of the service we recorded a timelapse of a KrakenSDR station tracking a weather balloon.

With the right geography of the receivers and transmitter, this allows you to instantly determine the location of a transmitter without needing to take multiple readings with a vehicle.ĭocumentation on the use of Kraken Pro Cloud is available on our Wiki at this page. It allows you to upload KrakenSDR direction finding data onto our central server, so that you can combine bearing data from multiple geographically distributed KrakenSDR devices. Kraken Pro Cloud is our online cloud mapping solution for KrakenSDR devices. We also do not guarantee any uptime for this service at this time. That means that all the intended features are not yet implemented, and that it may have multiple bugs.

We want to note that this software is still in ALPHA status. We are now releasing an early alpha version of our online 'Kraken Cloud Pro' service. If there are specific software bugs, please continue to post those as GitHub issues. If you have general questions, or support inquires please post there rather than through email so everyone can learn. We have also now released our KrakenSDR forum at. All the technical documentation and guides will remain on the GitHub Wiki. We also wanted to note that we now have our website live at This is mostly a marketing and general overview website. He also briefly demonstrates the KrakenSDR being used as five independent receivers in SDRAngel. The 3D model has been uploaded to Thingiverse for Twitter DemosĪaron (whom we mentioned earlier) has also been heavily posting on Twitter showing how he's been successful at getting his KrakenSDR running on a SteamDeck, a new type of handheld gaming device from Valve. He has posted an excellent and comprehensive document on our forums detailing his setup and experiences.Īt the same time he has also created a nice 3D printed frame assembly which can hold the KrakenSDR and Raspberry Pi 4 as one unit. KrakenSDR user Adrian has been experimenting with a KrakenSDR Passive Radar setup in his backyard.
