How space technology is bringing

green wins for transport

1 Space technology is developing fast, and, with every advance, it is becoming more accessible to industry. Today, satellite communications (satcoms) and space-based data are underpinning new ways of operating that boost both sustainability and profitability. Some projects are still in the planning stages, offering great promise for the future. However, others are already delivering practical results.

2 The benefits of space technology broadly fall into two categories: connectivity that can reach into situations where terrestrial technologies struggle to deliver and the deep, unique insights delivered by Earth Observation (EO) data. Both depend on access to satellite networks, particularly medium earth orbit (MEO) and low earth orbit (LEO) satellites that offer low-latency connectivity and frequently updated data. Right now, the satellite supplier market is booming, driving down the cost of access to satellites. Suppliers are increasingly tailoring their services to emerging customer needs and the potential applications are incredible – as a look at the transportation sector shows.

3 Satellite technology is a critical part of revolutionizing connectivity on trains. The Satellites for Digitalization of Railways (SODOR) project will provide low latency, highly reliable connectivity that, combined with monitoring sensors, will mean near realtime data guides operational decisions. This insight will help trains run more efficiently with fewer delays for passengers. Launching this year, SODOR will help operators reduce emissions by using the network more efficiently, allowing preventative maintenance and extending the lifetime of some existing trains. It will also make rail travel more attractive and help shift more passengers from road to rail (that typically emits even less CO2 per passenger than electric cars do).

4 Satellite data and communications will also play a fundamental role in shaping a sustainable future for road vehicles. Right now, the transport sector contributes around 14% of the UK’s greenhouse gas emissions, of which 91% is from road vehicles – and this needs to change.

5 A future where Electric Vehicles (EV) dominate will need a smart infrastructure to monitor and control the electricity network, managing highly variable supply and demand, as well as a large network of EV charging points. EO data will be critical in future forecasting models for wind and solar production, to help manage a consistent flow of green energy.

6 Satellite communications will also be pivotal. As more wind and solar installations join the electricity network – often in remote locations – satcoms will step in to deliver highly reliable connectivity where 4G struggles to reach. It will underpin a growing network of EV charging points, connecting each point to the internet for operational management purposes, for billing and access app functionality and for the users’ comfort, they may access the system wherever they are.

7 Satellite technology will increasingly be a part of the vehicles themselves, particularly when automated driving becomes more mainstream. It will be essential for every vehicle to have continuous connectivity to support real-time software patches, map updates and inter-vehicle communications. Already, satellites provide regular software updates to vehicles and enhanced safety through an in-car emergency call service.

8 At our company, we have been deeply embedded in the space engineering for more than 40 years – and we continue to be involved with the state-of-the-art technologies and use cases. We have a strong track record of translating these advances into practical benefits for our customers that make sense on both a business and a sustainability level.
