2.5.6.4. Description of typical obstacle avoidance scenarios
Trees, poles:
within 20 meters, obstacle avoidance radar can detect the obstacle, and
continuously showing warning data. When the distance is less than 18 meters, the drone
will brake automatically to ensure safety.
Wires:
Take the 1.5-cm-diameter wire as an example, because the reflection of the wire is
poor, the radar will be able to detect the wire 13m before the it when the drone is flying
right towards the wire at a speed of 3m/s. The thinner the wire or the higher the flight
speed is, the poorer the obstacle avoidance effect will be.
Notes:
1. When using the radar module, follow the local radio regulations and legal
requirements.
2. For obstacles of different sizes and materials, the effective working range of the radar
module will vary. For example, pedestrian, power cables, dry branches and conifers,
the effective detection distance will decrease. Please operate carefully.
3. Radar modules are suitable for flat terrain and may cause false alarms when the slop
angel is large.
4. When the surface beneath the drone is less than 1.5m, it is prone to cause false
alarms.
5. Never disassemble the radar module by yourself. Otherwise improper installation
might cause malfunction of the radar.
6. Do not crush or squeeze the housing of radar module.
7. Radar modules can be used normally in rainy days, and radar detection performance
might decrease by 10-20%.

RTK Function (Optional)
2.5.7.1.
Introduction
RTK can achieve centimeter-level positioning accuracy to improve the accuracy of
agricultural plant protection. When RTK is activated and GNSS signal is good, the drone
will start the dual antenna direction finding function, which not only has high directional
accuracy, but also can be operated reliably in places with strong magnetic interference
such as high voltage power line and metal building.
2.5.7.2. RTK Airborne Terminal Setting
RTK services can be obtained by:
Step1.
Set the base station to base station mode according to 2.4.7.3.
Step2.
Click on the satellite status in the top menu bar of the main interface to enter the
RTK setup interface.
Step3
Set the data source to "Datalink". After connecting to the base station
successfully, you can view the RTK status. Wait for the display to show "Fixed
