Well there is also Vision Positioning System module but that isn't really important for outdoor flight. Lightbridge, however, is a HUGE difference offering 5x the range of a Standard. One advantage for a Standard is flight times are listed as 2 minutes longer. I just picked up a Standard while they are on sale @ $499. It's basically an upgraded Vision+. Obviously it won't match my Advanced & Pro for range, but my plan in purchasing the Standard was for use in autonomous missions now that the Standard SDK has been released. It is a less expensive investment for a risky flight and that extra 2 minutes of flight time might be the difference between making it back or falling a mile & a half short!
