DJI Mavic Air in the air. The Mavic Air was announced in January 2018 as a more portable development of the DJI Mavic. [1] [2] Like the Mavic, the Mavic Air is a foldable quadcopter, though the arms and propellers fold to be flush with the side of the drone as opposed to the Mavic's over/under configuration. [1]
On 22 April 2023, DJI released the Mavic 3 Pro and Mavic 3 Pro Cine, replacing the original Mavic 3. [28] [29] The Mavic 3 Pro was the first DJI drone to have three optical cameras, with a medium 48MP 1/1.3" CMOS telephoto camera being added in addition to the original two cameras. [30] [31] Flight time was slightly decreased to 43 minutes. [31]
The system error, including position error, ..., may not exceed three percent of the calibrated airspeed or 5 knots (9.3 km/h), whichever is greater, throughout the [operating speed range for the aircraft].
The Mini 4 Pro was released on 25 September 2023. [24] The Mini 4 Pro introduced the Omnidirectional Vision Sensing collision avoidance system, which uses four fisheye and two downward binocular vision sensors and a time-of-flight sensor. [25] The drone also features an O4 transmission system transmitting 1080p footage up to 20 km away. [26]
Gimbal lock is the loss of one degree of freedom in a multi-dimensional mechanism at certain alignments of the axes. In a three-dimensional three-gimbal mechanism, gimbal lock occurs when the axes of two of the gimbals are driven into a parallel configuration, "locking" the system into rotation in a degenerate two-dimensional space.
Illustration of a simple three-axis gimbal set; the center ring can be vertically fixed. A gimbal is a pivoted support that permits rotation of an object about an axis. A set of three gimbals, one mounted on the other with orthogonal pivot axes, may be used to allow an object mounted on the innermost gimbal to remain independent of the rotation of its support (e.g. vertical in the first ...
This is because even though the missile is moving at a low speed, the rocket motor's exhaust has a high enough speed to provide sufficient forces on the mechanical vanes. Thus, thrust vectoring can reduce a missile's minimum range. For example, anti-tank missiles such as the Eryx and the PARS 3 LR use thrust vectoring for this reason. [8]
Some more expensive heading indicators are "slaved" to a magnetic sensor, called a flux gate.The flux gate continuously senses the Earth's magnetic field, and a servo mechanism constantly corrects the heading indicator. [4]
