We primarily use the Sentinel-1 constellation, which consists of two satellites Sentinel-1a and Sentinel-1b operated by the European Space Agency (ESA) on behalf of the European Com-mission Copernicus scheme. Sentinel-1 provides a good balance between spatial coverage, resolution and repeat time. The satellites produce images every six days which are hundreds of kilometres wide with a resolu-tion of 20 m x 4 m on the ground. Sentinel-1 also has a free, open-access data policy allowing anybody to obtain the data free of charge. However, some applications may require the use of higher resolution, more expensive, commercial radar satellites.
Our data consists of time series and average velocities. The accuracy of an individual data point in the time series is typically a few mm and depends on the properties of the reflector. The average velocities are more accurate, achieving accuracies of approximately a millimetre per year.
We are happy to explain the key concepts of InSAR and what the data show generally, but it is up to you to use our data in conjunction with other information to build up a complete picture of the processes/area you are interested in.
We are launching the portal on trial price basis throughout our phased launch, so stay tune for more details.
Our data covers the entirety of the UK, with most of the country having historical data going back five years.
Yes, please get in touch with our team for more information.
We aim for one working day or less. There are a couple of manual steps at the moment, but this will become fully automated in due course, bringing the time down to minutes or even seconds.

Sentinel-1 acquires a new image along each satellite track every six days over the UK and the rest of Europe. These satellites follow an approximately polar orbit meaning they fly approx-imately north-south. Some of these satellite tracks have the satellite flying from south to north (known as ascending orbits) whilst others have the satellite flying from north to south (known as descending orbits). These different satellite tracks overlap and provide complemen-tary information. Most places in the UK are imaged by four different satellite tracks, each of which is updated every 6 days. This means that over 6 days, there will generally be 4 new measurements over all the satellite tracks which image a particular site.
We are always looking to improve and strive for excellence. Above all, we value your feedback, please get in touch if you're not entirely satisfied.
