SPOT 5 Imaged by Pléiades for its 10th Birthday
Toulouse, April 1, 2012–Not long after arriving on orbit, PlĂ©iades 1A set its sights on sister satellite, SPOT 5.
Unique Rendezvous
PlĂ©iades’ 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 PlĂ©iades’ 700-km vantage point when it pointed its sensors at SPOT 5 orbiting 100 km below. An impressive achievement, since PlĂ©iades 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 PlĂ©iades 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.
