Embedded Global Positioning System-Inertial Navigation System

An Embedded Global Positioning System-Inertial Navigation System (GPS-INS) is a navigation system that combines the capabilities of both GPS and inertial navigation systems.

GPS is a satellite-based navigation system that provides accurate positioning and timing information. It uses a network of satellites to determine the receiver's location, velocity, and time. GPS is widely used in various applications, including navigation, mapping, surveying, and tracking.

On the other hand, an inertial navigation system (INS) is a navigation technology that uses a combination of accelerometers and gyroscopes to measure the acceleration and rotation rates of a moving object. By integrating these measurements over time, an INS can estimate the object's position, velocity, and attitude.

When GPS and INS are combined in an embedded system, it is called a GPS-INS. This integration allows for more accurate and reliable navigation, especially in environments where GPS signals may be obstructed or unavailable, such as in urban canyons, tunnels, or indoor areas.

The GPS-INS system continuously receives GPS signals and combines them with the inertial measurements to provide accurate and continuous navigation information. The GPS measurements help correct the errors that can accumulate in the inertial measurements over time, while the inertial measurements help bridge any gaps in GPS coverage.

GPS-INS systems are commonly used in various applications, including aviation, maritime navigation, autonomous vehicles, robotics, and military systems. They provide precise and reliable navigation information, enabling accurate positioning, velocity estimation, and attitude determination.
