Navigation

Research Scientist

Navigation is the art and science of determining the position and course of an object of interest. In the past the term was most often applied to ships, but today navigation is more important than ever and affects everyone.

The cutting edge of navigation technology is focused not only on ever improving accuracy, but also on increasing availability to allow users of smartphones and other devices to navigate indoors and out, as well as reliability to protect users of navigation products from errors.

Our research on navigation technologies ranges from GNSS-based precision aircraft landing to wireless positioning and navigation technologies for outdoor and indoor use. In addition, we conduct research on navigation technology solutions for autonomous vehicles either on land, in the air, on water, or beneath the sea.

Research and Activities

Ground Based Augmentation System (GBAS) for precision aircraft landing: our research activities in this field are focused mainly on evolution of single frequency GBAS CAT II/III based on GPS L1 towards multi-constellation, multi-frequency (MCMF) GBAS covering such aspects as system architecture and requirements definition, characterization of the operational environment in terms of interference, multipath and anomalous ionosphere (scintillation and gradient effects), and MCMFGBAS ground integrity monitor development. We are also participating in a number of projects concentrating on performance analysis and enhancement of single frequency GBAS CAT II/III design to ensure system certification for a wider range of geographical locations, including the high latitude regions of Norway and Northern Europe.

Indoor Navigation: the research work on indoor navigation consists of developing new solutions for allowing first responders and other user groups that require navigation as well as team situational awareness to operate seamlessly between indoors and out.

Autonomous Vehicle Navigation: SINTEF has undertaken activities focused on autonomous vehicle development, which almost universally require an application focused navigation solution. Our efforts in this field consist mainly of the development, testing and integration of multi-sensor navigation systems that also fit the potentially stringent Size, Weight, and Power (SWAP) constraints posed by the target platform.

ITS Applications: key research topics include vehicular navigation and performance evaluation of vehicle-borne mobile mapping systems for inventory of public areas in degraded GNSS signal environments (urban areas, tunnels etc.).
