jak ustawić antenę automatycznego śledzenia z bezprzewodowym łączem danych wideo.

Kupujący: I would like to ask you a technical question about the automatic tracking of the gimbal:
We currently hold the flight controller by hand, o 2 meters higher than the automatic tracking gimbal. jednak, the height displayed on the automatic tracking gimbal screen is always negative, and the value is still relatively large. According to our understanding of reading the automatic tracking gimbal documentation, this Alt parameter should be the altitude difference calculated by calculating the GPS information of the flight control end and the automatic tracking gimbal end, so the current Alt parameter shows a negative number, what is the reason?

Kupujący: ExtGPS is currently enabled, and the ALT interpretation of the protocol also selects GPS.

iVcan: If it is Baro, change it to GPS.

Kupujący: ExtGPS is currently enabled, and the ALT interpretation of the protocol also selects GPS.

iVcan: Zgadza się, how much is negative? Seventy or eighty?

Kupujący: Is the working current normal after the machine is powered on?

iVcan: It is correct.

Kupujący: This is our flight controller, with a GPS module.

Kupujący: We went downstairs to test again, and now the height is -4.

iVcan: That’s probably within the margin of error, fly the plane to see the effect.

Kupujący: Looks like it should be fine.
