 There's no assisted GPS or battery backup so every time the Crazyflie is powered on the GPS module does a cold-start, which a while to get a fix. During ideal conditions it should be 42 seconds (according to datasheet) but during testing we have seen times closer to 4-6 minutes. The plan is to improve this in the future by implementing assisted GPS (downloading almanac on the PC and transferring via CRTP). There's no assisted GPS or battery backup so every time the Crazyflie is powered on the GPS module does a cold-start, which a while to get a fix.
