GNSS Dataset
smartLoc 

Introduction

The following datasets were created during the smartLoc project. Our intention is to create one starting point for different groups in varying research areas involving GNSS (Global Navigation Satellite System). These groups could be within the automotive sector focusing on Advanced Driver Assistent Systems. They could also be robotics researchers with focus on localization and mapping or work within the field of communication engineering etc.
Our datasets contain GNSS data from two sensors recorded during real-world urban driving scenarios. On the one hand a mass-market receiver is used and on the other hand the ground truth is derived from a highly accurate reference receiver.
 


You will find the following data on our website:

  • Raw data and fix position of a mass-market receiver
  • Ground truth data from a reference receiver related to the mass-market receiver
  • Ego motion data from CAN
  • Four representative scenarios in urban areas with up to 49% of Non-line-of-sight
  • Uniformly time scaled
  • Raw data from the reference receiver
  • Labeled raw data for Line-of-sight and Non-line-of-sight

More information about each dataset and the setup of our sensors is shown on separate pages. We would be happy to know who uses our datasets or to get an information about the achieved results. Do not hesitate to contact us via e-mail or phone.

Information to Ground truth data

We generated the ground truth by fusing the BESTPOS message of the NovAtel receiver - Details on page 385 in OEM6® Family Firmware Reference Manual (Revision 9) - with the ego motion data from the CAN sensor of our test vehicle Carai 1.
