I have not used my drone in over a year, and now I cannot get a GPS lock which is resulting in the in 3 flashing green lights in safe flight mode. I have tried the following fixes, but my drone still isn't getting a GPS Lock. Any thoughts?
- Updated the firmware of the ST 16 to v03.01.b30
- Updated Drone firmware to Autopilot V1.16, Gimbal V1.25, Camera V3.3.34(A), RealSense Version NA
- Made sure my batteries are fully charged
- Left the drone and St16 in open area for over 5+ hours to make sure the Satellite almanac updates (over 18 satellites connect to both drone and ST-16)
- charged the unit so that the GPS battery is full. Operating voltage is 2.75 volts and when I turn off the drone power it drops to 2.72 volts
- Recalibrated the Compass
- Turned on and off the GPS option under "setting calibration"
