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.

How Drones are Transforming Construction and Infrastructure Inspection

Posted by Will Dillingham on Apr 6, 2020 10:00:00 AM

Ensuring our infrastructure is running, and our job and construction sites are safe should be a top priority. However, the maintenance and inspections needed is inherently dangerous and often time-consuming and repetitive, making drones instrumental and valuable tools.

Drones can capture all kinds of data from images and videos, LiDAR scanning, mapping data, and a variety of data types related to air conditions, location, and precision location, including inertial data. As a result of using drones for these initial inspections, we can more quickly pinpoint the location and cause of the problem, and ensure that fewer humans are put in harm’s way.

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...

Direct Georeferencing for Photogrammetry Using Inertial Labs INS-B

Posted by Will Dillingham on Mar 27, 2020 10:30:00 AM

Aerial Photogrammetric analysis may be applied to a single image or high-speed imagery and remote sensing to detect, measure and record complex 3D motion fields.

This is done by feeding measurements and image analysis into computational models that estimate the relative motions and positions with increasing accuracy.

While in its early days it was used mostly for topographic mapping, it’s application base has recently expanded into numerous industries. Modern sensors and software capabilities allow for the creation of precise 3D renderings and point cloud generation which is widely used in industries such as Filming, Sports, Game Development, Agriculture, Real Estate, Forensics, Land Surveying, and in Civil or Architectural Engineering.

For these different applications, two methods of photogrammetry are used in practice today, Aerial Triangulation (AT), and a more modern approach, Direct Georeferencing...

Affordable and Hassle-Free Solutions for Obsolete Sensors

Posted by Inertial Labs on Mar 23, 2020 3:29:11 PM

Replacing existing sensors is not as easy as purchasing a new sensor and plugging it into the existing hardware. There are many other factors that companies must consider as they seek replacement solutions, and they typically are both costly and time-consuming.

Inertial Labs customers will always be taken care of with the intentional focus directed to the needs presented by customer requirements. One way we take care of our own is by offering an option to start using our sensors as direct replacements for the obsolete or discontinued sensors.

In fact, we can put our sensors into a form factor that is compatible with the aging, expensive, or no-longer-available products. Inertial Labs wants to reduce R&D and programming time for customers seeking replacement solutions for discontinued sensors. We can help solve the problems they face due to obsolete sensors in four critical ways...
