algorithm accuracy of FY-3ZT will be influenced, and may even lead to large errors attitude
algorithm so that the FY-3ZT can not work properly.

FY3-ZT autopilot integrated flat-GPS passive antenna. This antenna has very strong ability to
receive signals, and can effectively overcome the false signal reflected from the ground. When
installing the FY3-ZT, please place it horizontally, and keep the metal objects away. No
transmitting antenna should be around the GPS antenna. Such as communication link antenna
or image link transmitting antenna; if the transmitting antenna too close to the GPS antenna ,it
will increase the noise signals which led to instability in positioning ,positioning error
increased and so on, in more serious cases ,it may couldn’t positioning .

Place the data radio module as far as possible away from the GPS module, AHSR & GPS
module and the servo, in order to avoid interference to the above equipment. Data radio
antennas should be installed vertically upward or downward. Communications link is basically
depends on the user's specific application, if the user’s aircraft only can be operated within
radius of 5 km, then a common data transmission module can be qualified; and if the user
needs to monitor the aircraft's flight state or control the aircraft from a long distance, then you
need an advanced data radio .The communication link used by FY3-ZT autopilot can be
half-duplex or full-duplex data radio. The uplink is responsible for transmit the orders from the
ground person, and transmit waypoint planning. The downlink is responsible for transmit the
flight status and other remote sensing information. The asynchronous serial interface protocol
between FY3-ZT autopilot and communications link is RS232-TTL level, the baud rate is
19200.
The data radio module of some bands (eg 433M) is easily to interfere the servo when the
electromagnetic emission. To solve these electromagnetic compatibility problems, you can through
arrangement of wire and place the antenna away from the easy interfered equipments, you also can
reduce the interference through rounds the magnetic core on the servo .As bellowing:
