Whether you need backward compatibility, robust communications, or programmability, Sparton has the solution.
The in-field calibration of a digital compass in the application of end use cannot be taken for granted.
Helium can interfere with the function of MEMS devices such as accelerometers and gyroscopes.
The oceans span over seventy percent of the Earth’s surface and are one of the biggest contributors to human civilization. Learning to navigate its waters has provided exploration, resources, food, trade and migration. Much of the oceans still remain unexplored and untapped due to its hostile environment, unpredictability, and high operational costs. The National University […]
There are a number of ways to represent the orientation of an object in 3-dimensions. One common way is to use Euler angles (like pitch, roll, and yaw). Euler angles were developed by Leonhard Euler, a brilliant 18th century Swiss mathematician. There are, however, ambiguities that arise when using this convention. If the pitch happens […]
The Sparton NorthTek™ application platform is a powerful, industry-leading feature that positions Sparton’s inertial sensors as the world’s only fully programmable digital compasses – allowing virtually limitless customization and application. NorthTek™ was developed as a hardware software integration tool and expanded to be a full runtime environment. While most inertial systems only allow the user to modify […]
Most common issues when using a magnetic compass Calibration Calibration has long been a source of error in the eventual heading readings of a magnetic compass. With many systems, the calibration is tedious and is often referred to as the “Chicken Dance” due to its complexity requiring the user to rotate to multiple positions while […]
Many navigation systems today rely on the use of Kalman filters. The Kalman filter is an algorithm that uses a series of measurements over time, even those containing “noise” and other errors, and produces estimates that tend be more accurate than those based on a single measurement. The Kalman filter was developed back in the […]
RoHS Compliant Compasses Sparton RoHS (Restriction of Hazardous Substances) compliant digital compasses are fully compatible with systems that require high-reliability standards due to extreme-environment operating conditions. The materials and chemicals used in the design, assembly, and manufacture of Sparton digital compasses do not exceed the thresholds set forth in the RoHS Directive 2002/95/EC for Lead, […]
There is so much terminology when talking about navigation products that it can be confusing. What is an Attitude Heading Reference System (AHRS) and how does it differ from an Inertial Navigation Systems (INS)? Some products have GPS integrated and others don’t. Welcome to Compass Terminology 101. Let’s go over the basics of these terms […]
