With roundabouts just be aware that they don't indicate on entering the roundabout, only when they are going to exit. So keep a close eye on that especially on smaller ones (not that there are many).

Jump to postAirliners have no business flying in a combat zone. They've done that and it ended badly for reasons entirely unrelated to GPS (though at least one incident was caused by a lack of GPS).

Jump to postI wasn't certain what assumptions would go into that precision, but yeah, with a full dual-antenna single GPS system, you essentially have a differential GPS with extremely high precision. With carrier-phase tracking, a differential GNSS can get better than 1 cm accuracy in relative position, assum...

I'd argue they're perfect for aircraft. The bigger the distance between the antennas, the better - and stick the second antenna in the tail. You also get GPS-based yaw (heading) and pitch backup measurements. They won't be hugely accurate, but could be useful when attempting to detect failed instru...

GPS positioning was never intended for civil navigation—it was a means for the military to manage movement, hence reliability was a small part of the risk analysis. It became a civil system after fielding in 90s. GPS was always (well, at least since the mid-70s) intended for civil navigation, espec...

Jump to postOK, then a question. Is typical modern suicide drone a sufficiently "noticeable" target for a WWII-era-style proximity-fused AA ammo? In theory, yes, the drone should be detectable.
