![]() ![]() When launched, the solar wings and radar opened together in a specific sequence that took around 10 hours to complete. After being released into orbit, the satellite gently ‘tumbled’ to stabilize before embarking on its elaborate routine. This crucial and complex deployment sequence was analyzed and dissected over and over again during the design phase. For the Sentinel 1-A satellite, Airbus Defence and Space Netherlands developed a technology with which the solar arrays cleverly deploy after the satellite has been delivered in space. The data will also be used to observe natural disasters such as floods, volcanic eruptions and landslides.īoth the Sentinel-1 and Sentinel-2 satellites have Dutch solar arrays. The comprehensive data from these measurements provide information about vegetation, earth and water cover, inland and coastal areas. Every ten days the satellite scans any point on Earth. The Sentinel-2 satellite continuously provides high-resolution images delivered in different band widths. Sentinel-1 is a radar satellite that continuously provides critical data for operational services such as mapping of inhabited areas and the impact on the environment, monitoring of movements of the earth’s surface, inspecting the marine environment, monitoring the Arctic and forests, management of water and floods, global services for food safety and humanitarian aid in crisis situations. Dutch solar arrays provide the power of several of the Sentinels. ![]() ![]() To support the operational needs of the Copernicus program, ESA is developing a new family of missions called Sentinels, meaning “gatekeeper”. ![]()
