GPS, IMU, and wheel encoders
As you know, the Global Positioning System (GPS) helps us to determine the global position of a vehicle with the help of GPS satellites. The latitude and longitude of the vehicle can be calculated from the GPS data. The accuracy of GPS can vary with the type of sensor; some sensors have an error range of within a few meters, and some have one within less than a meter. We can find vehicle state by combining GPS, Inertial Measurement Unit (IMU), and wheel odometer data and by using the sensor fusion algorithms. This can give a better estimate of the vehicle. Let's look at the position estimation modules used for the DARPA Challenge 2007.
The POS LV modules from Applanix are the modules used in the Stanford autonomous ...
