The Pléiades satellites provide 4 bands of data with a resolution 2 m resolution covering the visible spectrum and the near infrared, and a panchromatic product with a 0.5 m resolution. The first Pléiades satellite was launched December 2011 and the second was launched a year later, in 2012. Each of the satellites has a repeat cycle of 26 days, but due to innovative gyro systems, daily coverage of any point on the globe is possible. The same gyros also allow for the sensors to provide along-track tri-stereo acquisions, which in turn enables the production of high quality digital elevation maps.
Each of the satellites has a theoretical acquisition capacity of 1,000,000 km2 per day which entails a rapidly growing catalog of images. Futhermore a strong internal georeferencing allows for a 3m (CE90) image location accuracy without ground control points. The satellites have been designed with urget tasking in mind, and images can be requested from less than six hours before they are acquired.
