DJI T202008SS3 AGRAS Aircraft
Aircraft
The AGRAS T20 fcaturcs a brand-new design including a foldable frame and a
quick rclcasc spray tank and flight battery, making replacement, inetallation,
and storage easy. The stable and reliable modular aerial-electronics system is
integrated with a dedicated industrial flight controller, OCUSYNC 2.0 HD
transmission system, and RTK module It has dual IMUs and barometers and adopts
a propulsion control system redundancy design including both digital and
analog signals to ensure flight safety. The GNSS+RTK dual-redundancy system is
compatible with GPS, GLONASS, BeiDou, and Galeo. The T20 also supports
centimeter-level positioning” when used with the onboard D RTM. Dual antenna
technology provides strong resistance against magnetic interference. Te
upgraded spraying systerı lea lures ar improvement in the payload. Il alsu
tras a 4-caramel eleciruragr etic flow meter to ensure consistent spraying for
all sprinklers. The new-generation omnidirectional digital radar provides
functions such as terrain-following and obstacle sensing and circumventing in
all horizontal directions. The aircraft is equipped with a wde-angle FPV
camera that enables users to observe the landscape from the front of the
aircraft. The aircraft has a backup power system, which supplies power to the
aircraft for approximately 20 seconds when the Intelligent Flight Battery is
powered off due to malfunction during flight. This allows the aircraft to
avoid accidents and land safely Due to its industrial design and material, the
T20 is dustproof, waterproof, and corrosion-resistant. The aircraft has a
protection rating of IPX6 (IEC standard 60529), while the protection rating of
the aerial-electronics system, spray control system, propulsion ESC system,
and radar module is up to IP67.

Remote Controller
The Smart Controller 2.0 uscs tho DU OcuSync 2.0 transmission system, has a
maximum control distance of up to 3 km’, and supports Wi-Fi and Bluetooth
functions. The remote controller is equipped with a 5.5-inch bright, dedicated
screen that has the DUl Agras app built in, significantly improving smoothness
and stability. When the RTK cdongle is connected to the remote controller,
users can plan operations to centimeter-level precision. The Multi-Aircraft
Control mode of the remote controller can be used to coordinate the operation
of up to five aircraft at the same time enabling pilots to work efficiently.
Both the built-in battery and external battery can be used to supply power to
the remote controller. The total working time is up to 4 hours, which fully
meets the requirements for long and high-intensity operations.

The figure below shows the function that each control stick movement perfoms,
using Mode 1 as an example. In Mode 1, the left stick controls the aircraft’s
forward and backward moverments and heading while the right stick controls its
altitude and left and right movements.
Fly Safe
It is important to understand some basic fight guidelines, both for your protection and for the safcty of those around you.
- Flying in Open Areas: Pay attention to utility polee, power lines, and other obstacles. DO NOT fy near or above water, people, or animals.
- Maintain Control at Al Times: Keep your hands on the remote controller and maintain control of your aircraft when it is in fight, even when using intelligent functions such as the Route and A-B Route operation modes and Smart Retun to Home.
- Maintain Line of Sight: Maintain a visual line of sight (VLOS) with your aircraft at all times and avoid flying behind buildings or other obstacles that may block your view.
- Monitor Your Altitude: For the safcty of manned aircraft and other air traffic, fly at altitudes lowcr than 30 m (98 ft) and in accordance with all local laws and regulations.

Flying Considerations
- DO NOT use the aircraft to spray in winds exceeding 18 kph (11 mph).
- DO NOT use the aircraft in adverse weather conditions such as winds exceeding 28 kph (17 mph), heavy rain (precipitation rate exceeding 25 mm (0.98 in) in 12 hours), siow, or fog.
- The recommended maxımum operating altitude is 2 km (6,560 n) above sea level. DO NOT fIly over 3 km (9,842 ft) above sea level.
- Once the operating altitude reaches 1 km (3,280 t), the payload capacity of the spray tank is reduced by 2 kg. For every additional km, the payload capacity will reduce by a further 2 kg.
- Make sure that there is a strong GNSS signal and the D-RTK antennas are unobstructed during operation.
Return to Home (RTH)
The aircraft will automatically returm to the Home Point in the following
situations:
-
Smart RTH: You press the RTH button.
-
Failsafe RTH: The remote controller signal is lost.”
-
If there is an obstacle within 20 m of the aircraft, the aircraft decelerates and then stops and hovers.
-
If the aircraft comes within 6 m of the obstacle while decelerating, the aircraft stops, flies backward to a distance of approximately 6 m from
the obstacle, and hovers. -
The aircraft exits the RTH procedure and waits for further commands.
-
if Failsafe RTH is disabled (the defauit setting in the DJl Agras app), the aircrat hovers in place when the remote controller signal is lost.
-
Obstacle avoidance is disabled in Atitude mode (which the aircraft enters in situations such as when the GNSS signal is weak) and is not available if the operating environment is not suitable for the radar module. Extra caution is required in SUch situations.
Specifications
- The effective radar range varies depending on the material, position, shape, and other properties of the obstacle.
- Local regulations in some countries prohibit the use of the 5.8 GHz and 5.2 GHz frequencies. In some countries, the 5.2 GHz frequency band is only allowed for indoor use.
- Support for Galileo will be available at a later date.
- Hovering time acquired at sea level with wind speeds lower than 3 m/s.
