Stomnät i luften 2.0
The project Reference network in the Air, in Swedish: Stomnät i Luften 2.0 (SiL 2.0), is a research and innovation project with the overall goal to prepare the Swedish Transport Administration's construction operations for the challenges of the future regarding geodesy and machine control. The project runs over three years, started in 2019, is financed by the Swedish Transport Administration and has three major partners; Lantmäteriet, RISE and KTH. The Swedish Transport Administration also contributes to the project.
The core of the project is GPS / GNSS-based real-time kinematic (RTK) position determination that provides position uncertainty at cm level with the so-called project-adapted network RTK (PaNRTK) technology which is used for geodetic measurements, machine control etc. in large construction projects.
The SiL 2.0 project is based on a previous project, Stomnät i Luften, which was completed in 2011. However, the conditions and needs for the project-adapted network RTK have changed since the first project. Technology development is progressing rapidly and as the goals, needs and willingness to work as efficiently, uniformly, accessible and in as safe a manner as possible still exist, the Swedish Transport Administration decided to develop a continuation of the first project.
The SiL 2.0 project consists of 13 activities with different focuses. KTH is involved in most of these and is responsible for two of the activities:
- Investigation of the impact of ionospheric disturbances on GNSS positioning. The leader of the activity is Anna Jensen. E-mail contact Anna Jensen .
- Development of a new method for project-adapted geoid model. The leader of the activity is Mohammad Bagherbandi. E-mail contact Mohammad Bagherbandi .
