Sentinel-1a on ESA websiteBack to Missions

Launch: 3 April 2014
Orbit: Polar, Sun-synchronous at 693 km
Satellite: 2.8 x 2.5 x 4 m3
Objective: Monitoring sea ice, oil spills, marine winds & waves, land-use change, land deformation
Main instrument: Synthetic Aperture Radar (SAR)
Solar panels: 10 m
Radar antenna: 12 m

Project: Monitoring Camera System
Customer: Thales Alenia Space / ESA

Objective:

  • monitoring the deployment of solar panels and SAR antenna during LEOP
  • Earth viewing

The system is composed of:

  • 2 micro-cameras for solar panels and SAR antenna deployment monitoring and 1 micro-camera for Earth viewing
  • Control & processing unit for dedicated operations during deployments and interface to the spacecraft

The micro-cameras have a 70° field-of-view, for a mass of 110 g and a power consumption of 1.8 W

They are developed to sustain the extreme deep space environment
