YFQ-44A took flight today. Anduril has launched a new age of airpower with the push of a button.

From clean-sheet design to one-click takeoff in 556 days.

Developing passive radar using FM/TV illuminators of opportunity with RFSPACE NetSDR-X2 & USRP B210.

✈️ Aircraft detection via cross-ambiguity function processing
🔧 ECA adaptive clutter suppression
📊 Multi-target Kalman tracking
⚡ Real-time range-doppler mapping

No active transmission required. It is all a learning experience.

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.

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.

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.
