Using a single band GNSS receiver to improve relative positioning in autonomous cars
Paper i proceeding, 2016

We show how the combination of a single band global navigation satellite systems (GNSS) receiver, standard automotive level inertial measurement unit (IMU), and wheel speed sensors, can be used for relative positioning with accuracy on a decimeter scale. It is realized without the need for expensive dual band receivers, base stations or long initialization times. This is implemented and evaluated in a natural driving environment against a reference systems and against two simple base line systems; one using only IMU and wheel speed sensors, the other also adding basic GNSS. The proposed solution provides substantially slower error growth than either of the two base line systems.
