Sentinel-2

Dedicated to supplying data for Copernicus services, Sentinel-2 is carrying a range of technologies, such as multi-spectral imaging instruments for land, ocean and atmospheric monitoring. It's is delivering high-resolution optical images for land monitoring, emergency response and security services. The satellite carries a multispectral imager with a swath of 290 km. The imager provides a versatile set of 13 spectral bands spanning from the visible and near infrared to the shortwave infrared, featuring four spectral bands at 10 m, six bands at 20 m and three bands at 60 m spatial resolution.

Sentinel-3

Sentinel-3

Sentinel-3 is a low Earth-orbit moderate size satellite compatible with small launchers including VEGA and ROCKOT. It’s designed for a 7 year operational lifetime with 120 kg of hydrazine propellant allowing up to 12 years of continuous operations, including de-orbiting at the end of mission. The main objective of the Sentinel-3 mission is to measure sea surface topography, sea and land surface temperature, and ocean and land surface color with high accuracy and reliability to support ocean forecasting systems, environmental monitoring and climate monitoring.

Landsat

The Landsat program is the longest running enterprise for acquisition of satellite imagery of Earth, running from 1972.The most recent, Landsat 8, was launched on February 11, 2013. The images are a unique resource for global change research and applications in agriculture, cartography, geology, forestry, regional planning, surveillance and education. Landsat 8 data has eight spectral bands with spatial resolutions ranging from 15 to 60 meters; the temporal resolution is 16 days.

Planet Labs

Planet Labs

Planet Labs, Inc. designs and manufactures Triple-CubeSat miniature satellites called Doves that are then delivered into orbit as passengers on other rocket launch missions. Each Dove Earth observation satellite continuously scans Earth, sending data once it passes over a ground station. Together, Doves form a satellite constellation that provides a complete image of Earth at 3-5 m optical resolution and open data access. The images gathered by Doves provide up-to-date information relevant to climate monitoring, crop yield prediction, urban planning, and disaster response. For on demand access contact us.

Envisat Meris

Envisat Meris

Primary dedication of Medium Resolution Imaging Spectrometer (MERIS) is to Ocean Colour Observations, and secondary to the understanding of atmospheric parameters associated with clouds, water vapour and aerosols in addition to land surface parameters, in particular vegetation processes. MERIS has a high spectral and radiometric resolution and a dual spatial resolution. It acquires 15 spectral bands in the 390 - 1040 NM range of the electromagnetic spectrum, and it allows the programmability of its spectral bands in their width and position.
