Template:Infobox spacecraft class Sentinel-5 Precursor is an Earth observation satellite developed by the ESA as part of the Copernicus Programme to close the gap in continuity of observations between Envisat and Sentinel-5.
Sentinel-5 Precursor will be the first mission of a Copernicus Programme dedicated to monitoring air pollution. It's instrument will be ultraviolet, visible, near and short-wavelength infrared spectrometer called Tropomi. Satellite is build on a hexagonal Astrobus L 250 satellite bus equipped in S- and X-band communication antennas, three foldable solar panels generating 1500W and a hydrazine thrusters for station-keeping.
Tropomi (TROPOspheric Monitoring Instrument) will be a spectrometer sensing ultraviolet (UV), visible (VIS), near (NIR) and short-wavelength infrared (SWIR) to monitor ozone, methane, formaldehyde, aerosol, carbon monoxide, NO2 and SO2 in the atmosphere extending the capabilities of OMI from Aura satellite and SCIAMACHY instrument from Envisat.
Instrument will be taking measurements every second covering an area of approximately 2600km wide and 7km long in a resolution of 7x7km. Light will be separated into a different wavelengths using grating spectrometers and then measured with four different detectors for respective spectral bands. UV spectrometer is going to work in spectral range of 270-320nm, visible light spectrometer in 310-500nm, NIR in 675-775nm and SWIR in 2305-2385nm.
Instrument is split into four major blocks: UV-VIS-NIR spectrometers and a calibration block, SWIR spectrometer with its optics, instrument control unit and a cooling block. Total mass of Tropomi will be 200kg with a power consumption of 170W on average and a data output of 140 Gbits per orbit.
Instrument is being build by a joint venture between the Netherlands Space Office, Royal Netherlands Meteorological Institute, Netherlands Institute for Space Research, Netherlands Organisation for Applied Scientific Research and Airbus Defence and Space Netherlands.
First large contract for Sentinel-5P was signed in July 2009 for Tropomi instrument between the European Space Agency and Dutch Ministry of Economic Affairs which contributed €78 million. On 8 December 2011 ESA selected Astrium UK as a prime contractor for the satellite, signing contract worth €45.5 million Construction of the satellite itself was completed in May 2014, however it still awaits for its primary instrument.
