I've noticed that it now takes about 1-2 mins before takeoff to obtain 15-18 satellites. Before, it would take about 30 seconds. I posted this question in the DJI Mavic Air facebook forum and somebody said that satellites are acquired faster in the winter than summer and also trees growing leaves. I am flying in an open area so I don't know about the trees, but is there any truth behind the season? Maybe sun angle and amount of solar radiation??
