Satnav-enabled precision farming

What does satellite navigation have to do with sustainable development? Quite a lot, in fact. Satnav and other positioning, navigation and timing (PNT) technologies provide critical data that support green solutions across numerous sectors. From enabling smart mobility to optimising energy grids and facilitating precision farming, the potential for PNT to drive sustainability is immense.

GridCell is a technology designed to address escalating demands and challenges in modern power grid management. It combines five technologies, including precise timing reference that stems from combining GNSS with alternative back-up timing sources. GridCell promotes resilience, efficiency, renewable energy adoption and decentralised energy distribution, all of which are critical components of a more sustainable future. GridCell is being developed by Powerline (UK).

GreenAsphalt is a satellite-enabled solution for road repair, optimising the separation and volume control of milled material. Using GNSS, it accurately collects 3D data during milling and controls subsequent passes, eliminating the need for extensive pre-surveying. The system's precision will ensure optimal surface flatness, leading to long-lasting repairs and less maintenance. It will also reduce resource waste, lower emissions from construction machinery and promote efficient recycling of materials. GreenAsphalt is a project by Exact Control System (CZ).

Arli is a project to build a fleet of uncrewed ground vehicles to patrol the city and detect tasks that need to be taken care of by service staff, for example vegetation maintenance and damage in roads. The aim is to have robots equipped with GNSS, Light Detection and Ranging (LiDAR) technology and other positioning and navigation technologies that allow it to create 3D scans of the city. This project is currently being developed by DTU Space in collaboration with the Municipality of Aarhus, Capra Robotics and Bygkontrol and is expected to reduce resource wastage and promote environmentally responsible urban upkeep.
