Been tinkering with a web app to track Starlink DTC satellites using a 4x4 phased array at 1992.5 MHz. Starlink’s fast-moving, numerous satellites are perfect for testing dynamic beamforming. The app calculates orbital positions, picks the most optimal satellite to track, and visualizes it all with polar plots, azimuth/elevation charts, elevation predictions, ground tracks, and a 3D phased array sim. Check it out: rfspace.com/starlink/

Build that mission I shared in @Aaronia_AG in just a few clicks. Will of course open up my #Gitbook soon, but made this video just to show how fast you build a super simple mission by just tweaking the built in Factory Mission. #SIGINT #V6Plus #Aaronia

One of ny favourite IQ recordings is when my #PS4 downloaded a game on 2.4GHz. A great demo to show how smart #Bluetooth is, and why it is a bit hard to fully stop a Bluetooth speaker unless you have a wideband jammer. @Aaronia_AG #SIGINT #TeigenRF @TheCiscoWireles @CiscoChampion

I've set up a simulation of a Rotman lens to drive a phased array in Elmer. The matching of the ports is poor, causing lots of internal reflections, resulting in unwanted side lobes and poor channel separation. Nonetheless I think it still demonstrates the principle nicely 😊
