FlightAutonomy is expanded with an additional set of high-resolution stereo vision sensors placed at the rear in addition to the pair placed at the front as well as infrared sensing systems placed on the left and right sides. This network creates a total of 5-direction of obstacle sensing and 4-direction of obstacle avoidance, protecting the Phantom 4 Pro from more obstacles and giving filmmakers the confidence to capture more complex images.
The Phantom 4 Pro controller integrates an upgraded Lightbridge HD video transmission system that adds 5.8 GHz transmission support. The ability to choose between 2.4GHz and 5.8GHz allows pilots to cut through interference and eliminates image lag caused when flying in an area with extensive 2.4GHz frequency use. Normally, Wi-Fi video transmission systems use a 2.4GHz frequency to work with a controller using a 5.8GHz frequency as this prevents interference that can occur when both use the same frequency. If using the same frequency the video transmission system and the remote controller will interfere with each other, causing image lag. The use of two different frequencies has drawbacks in terms of flight performance. For example, flight performance will be affected when either of the two frequencies suffer interference.The Lightbridge HD video transmission system used in the Phantom 4 Pro uses TDM (Time Division Multiplexing) to transmit signals, allowing it to send controller signals and receive video transmission signals at the same frequency. As the 2.4GHz frequency band is often affected by Wi-Fi, 4G cell towers, and other types of interference in urban areas, a 5.8GHz band will increase transmission reliability. When switched on, the Phantom 4 Pro evaluates local signal levels, automatically choosing the transmission frequency with the lowest level of interference. This ensures the optimum range of a maximum video transmission of 4.3mi (7km)*A 5.5in 1080p screen integrated with the Phantom 4 Pro+ offers 1000 cd/m2 of brightness, more than twice as bright as conventional smart devices. It makes bright, vivid colors easily visible in direct sunlight. With this screen, a mobile device is not required, simplifying pre-flight preparations. As the DJI GO app is built into the screen, hardware and software can be fully optimized, further reducing video lag. Integration of an HDMI port, Micro SD card slot, microphone, embedded loudspeaker, and Wi-Fi connection allow images to be edited inside DJI GO to be shared almost instantly. Lastly, a five-hour battery life makes the Phantom 4 Pro + a complete aerial imaging solution.
Imagine holding the future in your hands. Designed to be powerful while lightweight, flexible while providing the stability you need, the Inspire 1 is DJI’s most advanced complete package. All of the latest aerial technology is packed into one simple, ready-to-fly system, putting you in the sky within minutes.
Carbon fiber arms give you the strength to maneuver in the air and they transform, moving out of the camera’s way at the flick of a switch. With a full 360⁰ unobstructed view, you now have the freedom to capture shots independent of the direction you are flying.
The all new 13 inch quick release rotors are built with the unique DJI "Z-Blade" design. They have been reinforced with a new carbon fiber compound material to ensure excellent performance with increased stability.
Brushless motors pioneered by DJI are now the standard in the multirotor industry. But the Inspire 1 takes the next step in brushless development by integrating curved magnets that fit flush around the edge of each motor. Although much more difficult to produce, these magnets eliminate airflow gaps within the motor, greatly increasing efficiency.
Several strands of copper wire have been replaced by a single, dense strand. Reducing the wasted space between wires results in more copper within each motor, providing more power and less resistance. A centrifugal pump increases airflow inside the neat, tight copper windings dissipating heat much faster while greatly increasing the life of the motors.
The revolutionary Electronic Speed Controllers (ESC) with sinusoidal drive replaces the square wave drive of traditional ESCs redefining the whole drive system. The patented algorithm in the ESCs have been tuned and customized specifically for the Inspire 1 offering features such as closed loop torque control and distinct functional redundancy with the highest efficiency and the most reliability.
A fully integrated intelligent battery powers your Inspire 1 and virtually manages itself.
When in flight, your remaining battery power is shown live, letting you know how long you can continue to fly. Advanced algorithms calculate the distance of your aircraft and estimated time to return home, letting you know when it’s time to fly back.
The battery reports the voltage of each cell, the total lifetime charges and discharges, and the overall health and battery status. All this helps you keep your Inspire 1 in the air and flying for years to come.
As it flies, the position of your Inspire 1 is constantly updated and recorded using a high-strength, intelligent GLONASS + GPS system. This dual positioning system enables higher precision and quicker satellite acquisition, allowing you to see where the aircraft is on a live map and giving it a point to hover at when you release the controls.
This is the "brain" of the entire system, receiving thousands of bits of data every second and translating that data into action as you fly. The Main Controller tells every part of your Inspire 1 what to do, calculates environmental conditions in real-time, and ensures that the aircraft responds to your control commands instantly.
Automatically keeping the Inspire 1 stable and steady during flight only looks easy, as DJI’s advanced Inertial Measurement Unit (IMU) handles everything. The IMU incorporates both a 6-axis gyroscope and an accelerometer to monitor miniscule changes in tilt and movement. This allows the aircraft to compensate and adjust immediately, holding its position at all times.
All of these features combine to put your Inspire 1 on autopilot when needed. If the battery runs low or connection with your remote controller is lost, the Inspire 1 uses its positioning system and smart flight technology to return back to you.
You can take off and land at the press of a button and keep your Inspire 1 steady indoors or when GPS satellites can’t be acquired with the new DJI Vision Positioning System.
DJI built the Vision Positioning System from the ground up, customizing it to meet the rigorous requirements in place for anything that handles position holding on our flying platforms.
This system combines visual data and sonar waves in a single unit, detecting both variance in patterns on the ground and current altitude. With this information, your Inspire 1 can hover in place and automatically raise or lower its arms as you liftoff or descend to the ground.
But the sonar and visual information is just one half of the fully integrated package: processing this information is handled by a dedicated CPU chip. This chip takes in feedback and outputs data in real-time, and is intelligent enough to distinguish between objects and ground patterns. All of this data is given to your Inspire 1’s flight controller, which in turn communicates with the entire aircraft.
The Inspire 2
takes everything that was good about the Inspire 1 and improves it. An
all-new image processing system records at up to 5.2K in CinemaDNG RAW, Apple
ProRes and more. It goes from 0 to 50mph (80kph) in just 4 seconds and
hits a maximum speed of 67mph (108kph) and has a max descent speed
of 9m/s for unheard of speed and agility in an aircraft this size. A
dual battery system prolongs the flight time to a maximum of 27 minutes
(with an X4S), while self-heating
technology allows it to fly even in low temperatures. FlightAutonomy has
been revised and developed specifically for the Inspire 2,
providing two directions of obstacle avoidance and sensor redundancy.
Increased intelligence adds multiple intelligent flight modes, including
Spotlight Pro, giving even single pilots
the ability to create complex, dramatic shots. An upgraded video
transmission system is now capable of dual signal frequency and dual
channel, streaming video from an onboard FPV camera and the main camera simultaneously, for better pilot and camera operator collaboration.
The Inspire 2 creative workflow has been completely optimized and is now capable of recording video
in CinemaDNG and Apple ProRes, and other common formats for
post-production in filmmaking. Also supported are FAT32/exFAT* file
systems, which allow fast copying of files direct from the CINESSD without additional software.
and downward vision systems enable the Inspire 2 to detect obstacles up
to 30 meters ahead, allowing for protected flight at up to 34mph
(54kph) at a controllable attitude angle
of 25°. Upward facing infrared sensors scan obstacles 16ft (5m) above,
adding protection when flying in enclosed spaces. Obstacle
sensing systems are active during normal flight, RTH and all
Intelligent Flight Modes.These sensors are core components of the DJI
FlightAutonomy system, which brings the below intelligent features to the Inspire 2:
Pro is a powerful tracking mode that allows even single pilots to
capture complex, dramatic images. It uses advanced visual tracking
algorithms to lock onto a subject during flight, regardless
of the direction that the Inspire 2 flies, creating shots that would
once have required a dedicated camera operator. If the gimbal comes
close to reaching its rotation limits, the
Inspire 2 itself will rotate in the same direction without affecting
flight control or the shot being captured to free up gimbal movement.
has two shooting modes, Quick Mode and Composition Mode. In Quick Mode,
select an object to begin tracking. In Composition Mode, select the
subject and the tracking position. When
the subject enters the preset tracking position, press the shortcut to
begin tracking. The gimbal can be moved during shooting for composition
adjustments.Spotlight Pro is available in all Intelligent Flight Modes including ActiveTrack, TapFly, Waypoint and Point of Interest.
addition to Spotlight Pro, a range of other intelligent flight and
shooting modes are available. Obstacle avoidance is optimized when using
Point of Interest* and Waypoint* modes,
making complex shots simple and repeatable. Also available are
QuickSpin, TapFly and ActiveTrack, to simplify challenging shots.Smart Return to Home
Forward and downward vision systems allow the Inspire 2 to create a real-time map of its flight route as it flies. If the video transmission system signal is lost and Smart Return Home is enabled, it is able to fly home along its original route, and change to a straight line when it regains a signal. As it returns, it will use the primary camera to identify obstacles as far as 200m in front, allowing it to plan a safe route home. It is also able to reconnect more quickly after losing connection.
The latest update to DJI Lightbridge technology has an effective transmission distance of up to 4.3mi (7km)* and is capable of delivering both 1080p/720p video as well as the FPV view to pilot and camera operator. Users can also switch between 2.4GHz and 5.8GHz** control frequencies to cut through noise for greater signal stability.
A new wireless HD image transmission technology sends video information from the master controller to the slave controller and the two controllers can be up to 100m apart without loss of image quality.
Broadcasters can broadcast direct from the Inspire 2 using its dedicated 1080i50 and 720p60 transmission signal. Aerial live-streaming direct to TV is as simple as connecting the Inspire 2 remote controller to the satellite truck.Powerful Flight Performance
A new propulsion system optimized for power creates a new level of flight performance. The Inspire 2 flies at up to 67mph (108kph) descends at 9m/s and climbs at 6m/s. It can accelerate from 0 to 50mph (80kph) in just four seconds and flies at a max attitude angle of 40°. The two controller sticks are tuned for more sensitivity, making delicate maneuvers easier.
More power also allows the Inspire 2 to fly in more extreme conditions, including over 2500-5000m above sea level (using optional dedicated propellers), and in temperatures as low as -4°F (-20°C) using self-heating Intelligent Flight Batteries.
has been further enhanced through dual redundancy of key modules such
as the IMU and barometer. The intelligent flight control system monitors
the redundancy system, giving it accurate flight data.
The new obstacle sensing system helps the Inspire 2 sense and avoid obstacles, minimizing the risk of collision.
batteries mean that if a problem occurs on one battery the other is
able to continue flight long enough for a safe landing. At the same
time, the Inspire 2 propulsion system is driven a PWM signal with serial
port signal redundancy so that if PWM signals are lost, transmission
will continue through the serial port.
propulsion system has been tested for thousands of hours to ensure
reliability, when combined with key sensors and a dual-battery design,
overall flight reliability is significantly enhanced.
