We continue publishing our DF results with KrakenSDR. Lastly, we have tested KrakenSDR installed on a vehicle. Our setup includes 5-channel KrakenSDR, a Raspberry Pi 4, and an Android phone. We also utilized KrakenSDR mobile application to get turn-by-turn navigation commands. We looked for a strong transmitter, and finally were able to locate it!
One of the important and interesting applications of Software Define Radios (SDR) is radio direction finding, or simply DF. The most common use case for DF is physically locating an unknown radio emitter of interest. DF can be used to locate illegal transmissions, track assets, help rescue teams to find emergency beacons, etc. Recently, we acquired KrakenSDR for our research projects in our lab. There will be a series of posts about DF but in this post we will share our first DF results with you, which are really promising.
