Hi all.
I had an unusual issue the other day. It was my first night flight. A couple of things occured.
1. When setting up/preflight checks, it took longer than usual to aqquire the satelite lock.
2. Also during pre-flight, I had an `RC-Disconnect' warning, with total loss of signal (this should have given me a heads-up).
3. When I did take off, I took the drone vertically only, to a height of approx 60m. I did not move it around, due to the LED light being switched off during video/max weight issue (can't fit a strobe).
4. When I reached that height, I turned the drone & took a few test photos.
5. After taking the photos, I did a 360 degree video.
6. When I completed the video, I had another `RC-Disconnect' warning with a complete loss of video on my phone (I have the RC-N1 controlller).
7. This is when I panicked. I had no control of my drone. After a few seconds, the video came back on the phone. I swiftly brought the drone back down & landed.
The drone seemed ok.
I did do a check of the flight logs. This is where it gets strange. There are two logs for the flight, but one seems to be in the middle of the other.
The main log has the drone starting to take off, reaches a height of 1m (after 6 seconds) with `home point updated'. Then jumps to 4m 31s at a height of 60.6m. It says that downlink data is lost for 131 seconds.
The second log starts at 2m 23s, at a height of 60.5m, with the mode changed to P-GPS. The next notification is at 2m 24s, same height, saying `setting new return to home altitude of 102m (I had set this height in the settings previously). There is a notification in the second log which says `Mode changed to Tripod', which I can not find anything about. The second log finishes at 2m 35s saying ambient light too low. The main log is just the drone returning to the ground & landing. Now I must add that the temperature at the time was around -2 degrees.
My questions really are:
1. Is there a way of holding or pointing the controller at the drone, to minimise a loss of signal?
2. Was the low ambient temperature a factor?
3. Is `RC-disconnect' something I need to be wary of & is it a common occurence?4. What is tripod mode?
I am in the UK & fly the drone under VLOS rules.
