Digital Infrastructure enabling accurate Positioning for autonomous systems (DINPAS)

Important results from the project

The DINPAS objective was to develop, deploy and evaluate a digital infrastructure prototype for precise and reliable satellite positioning for the next generation of industrial autonomous systems with technical focus on autonomous airports. The prototype’s scope is a full-time State Space Representation (SSR) correction service from reference network to end user, using SPARTN and 3GPP/LPP protocols separately. With reduced spatial and temporal reliability, the project has demonstrated precision < 1 dm in both horizontal and vertical position.

Expected long term effects

The prototype is capable of meeting the precision requirements of a nationwide, Global Navigation Satellite Systems (GNSS)-based positioning service for the mass-market, but currently with insufficient reliability and stability. A continued evaluation of the system to increase the understanding of various error sources´ impact on time and position solutions by the end user is therefore necessary before the system can be used for applications with full autonomy.

Approach and implementation

The project implemented a new solution for area-based GNSS corrections in four regional networks with varying sets of physical reference stations and grids, and evaluated with self-integrated receivers. The project parties represented three countries and joint as well as work package specific meetings were conducted online at 1-week intervals for the majority of the project duration. Software updates were shared via public GitHub. Eight joint physical meetings and field campaigns were carried out at the various parties sites. The collaboration continues in INTI5
