generates as a part of the geomagnetic field in the calculation. So try to prevent the ambient
ferromagnetic substances disturbing the tracker to affect its accuracy.
2). Q: When do I need to make the true north calibration?
A:
Basically there is no such time. The true north calibration is originally designed to
provide a means to correct the error caused by the magnetic declination. If all aspects are
normal, it is usually unnecessary to make the true north calibration. General users should
not use this feature.
3). Q: How to make the data downlink more reliable?
A:
MFD AAT uses the audio channels to transmit data. A clean noise-free audio channel
with appropriate level can make the data transmission more reliable. It is suggested the
peak-to-peak value of audio output level of the image transmission receiver should be
preferably within 1~2V. If there is a microphone and amplifier circuit attached to the
transmitter, you need to remove them to get the best results.
