Sentinel 1C, a new radar satellite supported by the UK, was launched into space from French Guiana at 21:20 GMT yesterday.
The Sentinel 1C satellite launched on a VEGA-C rocket and will orbit 700 km above the Earth’s surface.
Part of the European Copernicus programme, it will use advanced radar technology to provide continuous imaging over land and sea, day and night, and even through cloud cover.
Science Minister Lord Vallance said: “The successful launch of this new satellite will further strengthen the Copernicus programme, which continues to collect vital long-term data allowing us to better understand our planet, respond to natural disasters, and tackle global challenges like climate change.”
UK industry is key to satellite development
The UK’s Earth Observation industry is integral to the Sentinel 1 satellites, and the UK Space Agency supports it.
Airbus Defence and Space (Portsmouth) developed the electronics subsystem of the key Synthetic Aperture Radar (SAR) instrument aboard the satellite.
Additionally, Enersys ABSL (Abingdon) supplied the battery for Sentinel 1C.
Justin Byrne, Head of Earth Observation and Science at Airbus Defence and Space UK, said: “Airbus in the UK has designed and manufactured the entire family of radar electronic subsystems for the Sentinel 1 satellites.
“This continues the UK provision of key instrument elements for all European Space Agency and European Union SAR satellites in orbit.”
Sentinel 1C’s role in Earth observation strategies
Once it reaches its intended orbit, Sentinel 1C will synchronise with Sentinel 1A, which is already in space.
These satellites will collaborate to deliver the Sentinel 1 mission, imaging the Earth and generating large amounts of data that are fed into the various services provided by Copernicus.
“The SAR instruments on the Sentinel 1 satellites have contributed greatly to the monitoring of Arctic sea-ice extent, routine sea-ice mapping, marine environment surveillance, land-surface motion risks, forest, water and soil management, as well as contributing to humanitarian aid and crisis situations,” explained Dr Chandra Taposeea-Fisher, Chair of EO Committee, UKspace trade association.
“Data from the Sentinel 1 satellites has been used throughout the UK EO community and by government, industry and academia. We welcome the successful launch of Sentinel 1C, opening a new chapter in the EO world.”
Long-term data collection for climate tracking
Unlike research satellites, Sentinel 1C imagery is designed to sustain reliable operational service and consistent, long-term data collection for key applications.
This is crucial for land and maritime monitoring, tracking of sea ice, emergency response to flooding and earthquake events, tracking climate variables and assessing the impacts of climate change.
In addition to its radar instrument, Sentinel 1C will also carry a new Automatic Identification System (AIS) developed by the International Maritime Organisation to help ships avoid collisions at sea.
The combination of radar images and AIS signals improves the monitoring of global shipping traffic and can also help detect piracy and other illegal activities.
Professor John Remedios, Director of the National Centre for Earth Observation, said: “The advent of operational radar satellites has been a huge boost to our ability to observe hazardous and extreme environments, for example, where people are vulnerable to earthquakes and volcanoes.”
He concluded: “Sentinel 1C will renew the extensive coverage and clever products which result from combining data from two radar satellites operating at the same time, allowing scientists and businesses to measure ground motion from glaciers to cities.”
This latest milestone for Copernicus follows the successful launch of another satellite – Sentinel-2C – in September this year. This satellite already provides high-resolution imagery and data – it is a powerful tool that enhances the UK and Europe’s capabilities in monitoring land and vegetation.
