What are Inertial Navigation Systems and Accelerometers?

If you’ve ever heard of inertial navigation systems (INS) or accelerometers, but weren’t sure what they were, then you’re in the right place. INSs and accelerometers are two incredibly important parts of the modern world and understanding their functions can help us better understand how things like self-driving cars, GPS tracking systems, and even gaming controllers work. Let’s dive into the details of these systems so we can learn more about them.

What is an Inertial Navigation System?

An inertial navigation system is a type of navigational aid that uses accelerometers, gyroscopes, and other sensors to track a device’s orientation and location in three-dimensional space. INSs use a combination of these sensors to measure linear acceleration (movement along a straight line) as well as changes in orientation (changes in direction). By measuring both linear acceleration and changes in orientation, INSs can accurately track a device’s movement over time. This makes it possible for devices such as self-driving cars to navigate without any external input.

What is an Accelerometer?

An accelerometer is a type of sensor that measures linear acceleration (movement along a straight line). Accelerometers are typically used to measure the motion of objects relative to gravity or other forces acting on them. For example, accelerometers are often used in gaming controllers to measure how quickly users move their hands or other body parts when playing video games. They can also be used to detect changes in orientation such as when a person turns their head from side to side or tilts it up or down. Finally, accelerometers can be used to detect vibration or shock waves from earthquakes or explosions.

Inertial navigation systems and accelerometers play an integral role in many aspects of our lives today—from self-driving cars to gaming controllers—and understanding how they work helps us make better use of them. With INSs and accelerometers at our disposal, we have access to more accurate information about our position than ever before. We have the power to use this data for all sorts of applications ranging from navigation systems and virtual reality experiences all the way through autonomous vehicles; creating new possibilities every single day!
