SEOSAT/INGENIO. Spanish Earth Observation Satellite

SEOSAT is a multispectral high resolution wide swath world coverage imager, designed for systematic acquisition of Spanish territory and minimum revisit time. It will be operational in 2016 with a nominal life of 7 years, having a Sun-synchronous orbit at about 670 km altitude, with orientation capability of +/- 35º from nadir.

SENER is prime responsible for the design, manufacturing, integration, alignment and verifi cation of the Primary Payload of the mission.

The Primary Payload is a High Resolution Optical Instrument. It acquires images in two channels: a Pan-chromatic (black & white) with 2.5 m resolution, and a Multi spectral with four bands (blue, green, red & NIR) with 10 m resolution. It works in pushbroom mode, providing 55km swath, which covers for more than 2,5 million of square km per day.

Selected confi guration:

  • Overall instrument size is 1,5 m x 1,5 m x 1,5 m
  • Instrument weight is 150 Kg
  • Instrument with two identical cameras
