The Operational Land Imager (OLI) and the Thermal Infrared Scanner (TIRS) are the two instruments carried on board Landsat 8 (also known as LDCM – Landsat Data Continuity Mission) satellite. These two sensors provide seasonal coverage of the global landmass at a spatial resolution of 30 metres (visible, NIR, SWIR), 100 metres (thermal) and 15 metres (panchromatic).
The Advanced Very High Resolution Radiometer is a broad-band, four or five channel (depending on the model) scanner, sensing in the visible, near-infrared, and thermal infrared portions of the electromagnetic spectrum. This sensor is carried on the National Oceanic and Atmospheric Administration's (NOAA's) Polar Orbiting Environmental Satellites (POES), beginning with TIROS-N in 1978.

Pleiades is a two-spacecraft constellation of CNES, introducing advanced technologies in Earth observation. Starting with the first launch in 2011, the Pleiades program follows the SPOT program satellite series services.
Proba-1 is a technology mission aimed at evaluating new hardware and software spacecraft technologies, onboard operational autonomy and testing Earth observation and space environment instruments. Proba-1 was successfully launched on 22 October, 2001 and was intended as a one-year technology demonstration mission, but has since had its lifetime extended to serve as an Earth Observation mission.
The Proba-V mission provides multispectral images to study the evolution of the vegetation cover on a daily and global basis. The 'V' stands for Vegetation. This mission is extending the data set of the long-established Vegetation instrument, flown as a secondary payload aboard France's SPOT-4 and SPOT-5 satellites launched in 1998 and 2002 respectively.
The RADARSAT family consists of a pair of Canadian Remote Sensing satellites: RADARSAT-1, Canada's first commercial Earth observation satellite developed to monitor the planet's natural resources and environmental changes, and RADARSAT-2, a jointly-funded satellite mission of CSA (Canadian Space Agency) and MDA (MacDonald Dettwiler Associates Ltd. of Richmond, BC), representing a Canadian government/industry partnership in a commercial venture.
BlackBridge, located in Berlin, owns and operates a constellation of five identical Earth Observation satellites. The constellation images up to five million square kilometres of earth every day and its archive of imagery grows by over one billion square kilometres every year. Its five metre pixel size imagery is suitable for an array of monitoring purposes.
ResourceSat-1 (also known as IRS-P6) was successfully launched into polar orbit on 17 October 2003 from Satish Dhawan Space Centre by the Indian PSLV-C5.
IRS ResourceSat-2 was successfully launched into its intended polar sun-synchronous orbit on 20 April 2011 from Satish Dhawan Space Centre by the Indian PSLV-C16.
SciSat-1/ACE is an atmospheric science mission of Canada. Through a 3rd party mission agreement ESA will make validated data from the ACE-FTS (ACE-Fourier Transform Spectrometer) available.
The purpose of the Sea-viewing Wide Field-of-view Sensor Project is to provide quantitative data on global ocean bio-optical properties to the Earth science community. Subtle changes in ocean color signify various types and quantities of marine phytoplankton (microscopic marine plants), the knowledge of which has both scientific and practical applications.
The SPOT (from French "Satellite pour l'Observation de la Terre") constellation has been supplying high-resolution, wide-area optical imagery since 1986. The last satellites, SPOT 6 and SPOT 7, will assure data continuity through to 2024. All of the SPOT satellites provide imagery in Panchromatic and Multispectral bands with a swath of 60km.
MODIS (or Moderate Resolution Imaging Spectroradiometer) is a key instrument aboard NASA's Terra (EOS AM) and Aqua (EOS PM) satellites. Terra's orbit around the Earth is timed so that it passes from north to south across the equator in the morning, while Aqua passes south to north over the equator in the afternoon. Terra MODIS and Aqua MODIS are viewing the entire Earth's surface every 1 to 2 days, acquiring data in 36 spectral bands, or groups of wavelengths.
TerraSAR-X and TanDEM-X dependably acquire high-resolution and wide-area radar images independent of the weather conditions. The two satellites feature a unique geometric accuracy that is unmatched by any other spaceborne sensor.
