P4 Multispectral - Drone DJI - Free user manual and instructions

USER MANUAL P4 Multispectral DJI

P4 Multispectral The P4 Multispectral is a high-precision drone capable of multispectral imaging functions. The imaging system contains six cameras with 1/2.9-inch CMOS sensors, including an RGB camera and a multispectral camera array containing five cameras, all at 2MP with global shutter, on a 3-axis stabilized gimbal. The spectral sunlight sensor on top of the aircraft detects the solar irradiance in real-time for image compensation, maximizing the accuracy of collected multispectral data. Image data can be used to generate multispectral maps for plant and soil status analysis. The aircraft has a built-in DJI

which provides precision data for centimeter-level positioning accuracy*. Multi-directional obstacle sensing is enabled by forward, rear, and downward vision and infrared sensors*.

• This should be used with Network RTK service, a DJI D-RTK 2 High Precision GNSS Mobile Station (purchased additionally) or post-processed kinematic (PPK) data (recommended when RTK signal is weak during operation). The Vision and Infrared Sensing Systems are affected by surrounding conditions. Read the User Manual to learn more.

Remote Controller The remote controller features DJI’s long-range transmission technology OcuSync that is capable of controlling the aircraft and the gimbal cameras at a maximum transmission range of 4.3 mi (7 km)*. Connect an iPad to the remote controller via the USB port to use the DJI GS Pro app to plan and perform missions. Export the captured images for analysis and create multispectral maps. The remote controller has a rechargeable LiPo battery with a maximum battery life of approximately 6 hours*. The figure below shows the function that each control stick movement performs, using Mode 2 as an example. The left stick controls the aircraft’s altitude and heading, while the right stick controls its forward, backward, left and right movements. The gimbal dial controls the camera’s tilt.

• The remote controller is able to reach its maximum transmission distance (FCC/NCC) in a wide open area with no Electro-Magnetic Interference, and at an altitude of about 400 ft (120 m). The maximum runtime is tested under laboratory environment, only for your reference. Pictures will only be taken when the shutter button is fully pressed. Left StickRight Stick

Fully charge the batteries before using for the first time.

Ensure to connect the Intelligent Flight Batteries to the charging hub as shown in the figure above.

Ensure that the Mode Switch of the Intelligent Flight Battery charging hub is set to the Charging Mode position.

2. Checking Battery Levels

3. Charging the Batteries

1. Downloading the DJI GS Pro App

Press once to check the battery level. Press once, then again and hold to turn on/off. A A

The latest version of DJI GS Pro is required when using with the P4 Multispectral. Search for DJI GS Pro* in App Store or scan the QR code to download the app on your iPad. When using your P4 Multispectral for the rst time, activate it using DJI GS Pro. Ensure that your iPad has access to the internet.

5. Preparing for Takeoff

4. Preparing the Remote Controller

Strong Weak Try to keep the aircraft inside the optimal transmission zone. If the signal is weak, adjust the antennas or fly the aircraft closer. Optimal Transmission Zone Unfolding the Remote Controller

Check that the propellers are secure before each flight. Black propeller rings go on motors with black dots. Silver propeller rings go on motors without black dots. Press the propeller down onto the mounting plate and rotate in the lock direction until secure. Remove the gimbal clamp from the camera. Power on the remote controller and the aircraft. Launch the app.EN

For a safe take-off, make sure that the Aircraft Status Indicators blink green slowly (using RTK* or GNSS for positioning). The following example includes instructions for 3D Map Area missions using DJI GS Pro.

• RTK positioning is recommended. Go to Mission View in DJI GS Pro, tap the icon or RTK on top of the screen to go to the RTK settings menu, and then select D-RTK 2 or Network RTK Account as the RTK data source. Enable the aircraft RTK at the bottom of the menu. Otherwise, the aircraft cannot use the RTK data.

• When multispectral camera has been selected in Camera View, this mission will not include RGB photos.

Combination Stick Command to start/stop the motors Left stick (in Mode 2) up slowly to take off Left stick down slowly until you touch the ground Hold for three seconds to stop the motors

Spinning propellers can be dangerous. Stay away from spinning propellers and motors. DO NOT start the motors in confined spaces or when there are people nearby.

Always keep your hands on the remote controller when the motors are spinning.

Stopping motors mid-ight: Perform the CSC to stop the motors. This function can be enabled in DJI GS Pro. Only stop motors mid-ight in emergency situations when doing so can reduce the risk of damage or injury.
