2. Only the power battery is allowed to supply power to the interface at the air unit, because high-definition image transmission requires high current, instantaneous current response and ripple of the power supply. Do not modify the sky terminal without permission, otherwise the link stability and graph transmission distance may be affected.
2.2.2 Installation and placement of standard omnidirectional antenna at GCS
1. The SMA connector of the antenna must be tightened;
2. The antenna shall be placed upward perpendicular to the GCS operation panel, keeping the flat surface of the antenna always facing the aircraft, and the antenna shall not be stacked or crossed. Please refer to the following image transmission:
2.2.3 Installation and placement of standard omnidirectional antenna at air unit
1. The SMA connector of the antenna must be tightened;
2. The antenna MMCX and IPEX interface must be tightly inserted;
3. On a multi-rotor UAV, the standard omnidirectional antenna at the air unit should be installed vertically downward from the plane of the fuselage; on a fixed-wing aircraft, the antenna can be installed vertically upward from the plane of the fuselage. Try to keep the flat surface of the antenna facing the ground in flight;
4. The antenna feeder wiring shall be far away from the equipment with large power current and serious electromagnetic interference, such as electrical adjustment and motor;
5. The standard feeder at the air unit shall not cross. The antenna body, feeder and SMA connector shall avoid direct contact with metal and
carbon fiber structural parts and keep a distance of at least 10mm;
6. Try to avoid placing the 4 antennas at the air unit together, and the distance between each other shall be at least 50mm; In flight, the communication between the aircraft and the GCS shall be prevented from being blocked by obstacles;
7. The connection between the antenna feeder at the air unit and the connectors at both ends shall not be pulled or bent excessively, otherwise the antenna will be damaged; if the antenna angle or orientation needs to be adjusted, only the middle part of the feeder shall be bent as far as possible.
Attention
As shown in the figure below, for small and medium-sized multi-rotor UAVs, the air unit antenna should be placed vertically downward from the arm to keep the flat surface of the antenna facing the direction of the GCS.
As shown in the figure below, for large multi-rotor UAVs, the air unit antenna should be placed perpendicular to the motor base to keep the flat surface of the antenna facing the direction of the GCS.
As shown in the figure below, for a fixed-wing aircraft, the antenna at the air unit can be placed perpendicular to the wing or vertical tail, and at the
same time, try to keep the flat surface of the antenna facing the direction
of the GCS.
2.2.4 Communication distance is not ideal, need the necessary information before the original technical support
1. The intuitive phenomenon that makes you think that distance is not enough.
- Signal loss: image loss, GCS status indicator is red
- Only image is missing (GCS status indicator is green)
2. The flight distance and flight height of the UAV when the above phenomena are observed
3. Flight test environment (provide photos or videos of the drone’s flight direction)
4. Check the communication related software information:
- Working Mode and Frequency Band of Image Transmission
- GCS, air unit Firmware Version
- UniGCS application version
5. Check the hardware configuration related to communication
- GCS antenna type, installation angle and service angle (photos provided)
- air unit antenna type, installation angle (photos provided)
- air unit power supply mode, power supply voltage? Is there a retrofit power module?
6. If the problem cannot be solved after checking the above information, please provide the flight test recording screen when the link information is opened in the UniGCS application when the distance is close to the limit.
