STX-21 Mount

A Stabilized Mount For Large Format Sensors

The STX-21 stabilized mount is an unparalleled option for large format sensors. The mount is essentially an electromechanical system based on the principle of streaming data from an IMU. It has become essential for capturing and processing airborne sensor data. This stabilized mount can easily drive the unit to a Nadir position. Proper Nadir or most vertical positioning is crucial to the optimal processing of vertical imagery for the positioning, rectification or ortho-rectification of data. The IMU data, which is streaming constant positional information to the computer (as much as 100 times per second), is processed and used to drive the electrical motors to continuously position the mechanical gimbal mount.

Contrary to other mount designs, the STX-21 open circular gimbal fixes the sensor system to the mount low as possible above the airplane hole. As the center of rotation is also located as low as possible, the sensor takes full advantage of the ±14° full range of correction in pitch and roll and ±29° of drift correction.

The mount self-calibrates within seconds and installs in four directions. Whether it is along, against, or even perpendicular to the direction of flight, the STX-21 adjusts to best fit the shape and layout of any aircraft. As a result, the mount can relocate on other aircraft is easy.


The new Micro STX Controller contains all the electronics necessary for the operation of the mount in flight. The controller must connect to an IMU, such as an Applanix, Novatel or another compatible device. If needed the STX controller can expand at will by adding several modules. These modules include the Track'Air Flight Management module, an Applanix AP IMU module, a Riegl Lidar control module, and more.

It is possible to limit the mount to a lesser degree when facing the fuselage or an obstruction, such as the side of a narrow hole. For example, of the 14° of the available pitch, limiting the mount to 8° can prevent it from touching an obstacle.
