SPOT 5 Imaged by Pléiades for its 10th Birthday
Toulouse, April 1, 2012 - Not long after arriving on orbit, Pléiades 1A set its sights on sister satellite, SPOT 5.
Pléiades' superior agility has enabled it to accomplish the unusual feat of imaging another satellite in flight. Both satellites are operated by Astrium.
The rendezvous took place from Pléiades' 700-km vantage point when it pointed its sensors at SPOT 5 orbiting 100 km below. An impressive achievement, since Pléiades 1A and SPOT 5 complete an orbital revolution of Earth in just one and a half hours, at a speed of 6.7 km/s for Pléiades 1A and 6.58 km/s for SPOT 5.
In the image, SPOT 5’s solar array is clearly visible to the right and the bright spacecraft bus and optical sensors to the left.
First of a New Family
SPOT 5, launched on May 5, 2002, has been acquiring medium-resolution (2.5 m) wide-swath (60 km) imagery for 10 years. Pléiades 1A, launched on December 16, 2011, is the first in a new generation of agile, quick-reaction satellites that will deliver high-resolution imagery (50 cm).
Pléiades 1A will be followed into orbit by SPOT 6 before the end of this summer, its twin Pléiades 1B later in the year and SPOT 7, currently scheduled to launch in early 2014. Designed around a very similar architecture and phased in the same orbit, this constellation of four satellites will ensure increased responsiveness and availability of data products at resolutions of 50 cm to 1.5 m through to 2024.
