Gyroscopes and the History of Stabilization for Remote Weapons Stations

Posted by Will Dillingham on May 11, 2020 5:43:09 PM
What is a Remote Weapons Station?

A Remote Weapons Station (RWS) is a remotely operated weapons platform that utilizes light and medium caliber artillery shells. Typically, an RWS contains sensing components (angular rates, accelerations, etc.), motor drives, a turret, and a computer. Today, companies like Electro Optic Systems Pty Ltd are patenting next generation Electro Optic RWS that are gyro-stabilized, combat ready, and built for precision targeting(1).

Since the two most important characteristics for an RWS are aiming speed and accuracy, advanced methods of stabilization are required to ensure that targets are correctly dealt with. The most important component in this task is the gyroscope.

Using Optics to Stabilize and Simulate Indirect Fire Control

Posted by Will Dillingham on Apr 1, 2020 3:30:00 AM

Optical data, when fused with an IMU, is useful for both dynamic and static applications depending on the level of computer vision implemented into the system. By using the IMU as a reference for orientation, optical data can be used to mitigate drift of the gyroscopes.

So how does a complex system take into account multiple forms of data from different systems? By recognizing the best qualities of each source.

By themselves, each sensor in a complex system is vulnerable to many sources of error. For the OptoAHRS-II, the trick is to use a combination of sensors that each compliment the others weaknesses.

For an IMU, drift of the gyroscopes is the biggest flaw; which is where optical data comes to the rescue. If the system can recognize that the frame of reference is not moving, then biases can be ignored, preventing the IMU from drifting in it's orientation calculations...

Attitude and Heading Reference System (AHRS) Supports Data Input From External Single or Dual GNSS Receiver

Posted by Will Dillingham on Mar 20, 2020 5:45:00 AM

The AHRS-II-P offers advantages over its competitors present on the market by recording and transmitting very accurate Heading, Pitch and Roll; a very appealing choice for applications involving motion control such as UAV’s, aircrafts, ships, or robotic devices.

After the ARHS-II-P is mounted onto it’s carrier base, a quick calibration procedure is performed and the device is ready to go. Among the many ways to perform these calibrations procedures, the most mention worthy is the Inertial Labs option for an ‘On-the-Fly’ calibration.


Test Results of the AHRS-II-P with External GNSS Input

For this test procedure, the Inertial Labs AHRS-II-P was mounted to the floor of a test vehicle. The external GNSS receiver was mounted to the ceiling, and the respective antenna was mounted on the roof of the vehicle. The test duration was approximately 25 minutes long, and was performed at an average speed of 25 mph (11.18 m/s) in the suburban area shown in the picture below...

How the Inertial Labs Digital Tilt Sensor (DTS) is Shaping Construction Safety

Posted by Will Dillingham on Mar 17, 2020 10:14:04 AM

As of today, the leading cause of fatalities and injury in the construction industry is due to a falling related incident. Data that was gathered by the United States Department of Labor and published by the Occupational Health and Safety Administration (OSHA) found that in 2017, falling incidents alone contributed to 39.2% of the total construction tragedies.

But how do these incidents happen?

Much of the conventionally used construction equipment is designed to safely extend a worker as far as possible in order to allow them to operate in difficult to reach places that current automated processes are not capable of doing...

Protection

Since there initiation into the market in 2015, OpenWorks Engineering has been seeking to revolutionize the industry of security. While many industries focus primarily on offensive strategies for Autonomous Unmanned Systems (AUS) protection, OpenWorks has pushed an innovative solution that revolutionizes the defensive playing field. In the beginning of 2018, Openworks began it's partnership with Inertial Labs and entered testing phases for it's most successful product line, SkyWall.
