Navigation is how everything moves around globally, and electronics have provided better solutions for appliances to work seamlessly. There are two broad navigation options for finding your location. One is a Global Positioning System (GPS) system, and the other one is by using the Inertial Measurement Unit (IMU). The IMU is nothing but a combination of accelerometers and gyroscopes. This paper puts light on the Inertial Navigation System (INS), which uses GPS and IMU to get navigation data. GPS and INS give us real-time velocity and position data required for navigation. However, GPS has a slow update rate, up to 1-10Hz, while IMU performs far better at gaining navigation data with an update rate up to 1KHz. IMU accumulates errors and drifts over time while GPS has a low update rate. These drawbacks make both systems unreliable when used alone. The proposed work talks more about the use of both sensors, and Raspberry Pi Zero using a sensor fusion technology. Removing drawbacks of both the sensors and the use of the Kalman Filter are discussed in the paper. © 2022 IEEE.
