I’m evolving our city’s police dept’s UAS program from just patrol use to broader spectrum public safety measures. The SWAT team is interested in using a drone as a “first breacher” recon for active shooter situations to reduce risk, but flying indoors without GPS can be challenging. I want to master the art of indoor maneuver using the Mavic Mini (with a cage). There’s a professional tactical drone we’re looking at but I’m a firm believer in shaping skills the hard way (no sensors) but safely (the cage), to then up the game when really understanding the problems (turning and going up/down stairs, etc.). The Mavic Mini is a great system, but everything is limited for indoor use without GPS.
