Sentinel-5 Precursor
Sentinel-5 Precursor (Sentinel-5P) is an Earth observation satellite developed by ESA as part of the Copernicus Programme to close the gap in continuity of observations between Envisat and Sentinel-5. It was launched in October 2017, and has a design life of 7 years. The TROPOspheric Monitoring Instrument (Tropomi) provides the most detailed methane emissions monitoring available.
Sentinel-5P is the first mission of the Copernicus Programme dedicated to monitoring air pollution. Its instrument, Tropomi, is an ultraviolet, visible, near and short-wavelength infrared spectrometer. The satellite is built on a hexagonal Astrobus L 250 satellite bus equipped with S- and X-band communication antennas, three foldable solar panels generating 1500 watts and hydrazine thrusters for station-keeping.
The satellite operates in an 824 km (512 mi) Sun-synchronous orbit with a Local Time of Ascending Node of 13:30 hours.
The 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, followed by successful integration with its primary instrument. From design to launch Tropomi cost €220 million.
The satellite was launched by Eurockot Launch Services onboard Rokot. The launch was originally planned for late 2014, but after multiple postponements, was launched on 13 October 2017 at 09:27 UTC from Plesetsk Cosmodrome Site 133. Sentinel-5P successfully reached its final orbit 79 minutes after lift-off.
Sentinel-5P carries a single instrument, the TROPOspheric Monitoring Instrument (Tropomi). Tropomi is a spectrometer sensing ultraviolet (UV), visible (VIS), near-infrared (NIR) and short-wave infrared (SWIR) wavelengths of light to monitor ozone, methane, formaldehyde, aerosol, carbon monoxide, NO2 and SO2 in the atmosphere. It extends the capabilities of the OMI from the Aura satellite and the SCIAMACHY instrument from Envisat.
Tropomi is taking measurements every second covering an area approximately 2,600 km (1,600 mi) wide and 7 km (4.3 mi) at a resolution of 7 x 7 km. The total mass of Tropomi is approximately 200 kg (440 lb) with a power consumption of 170 watts on average and a data output of 140 Gbit per orbit.
Tropomi was built 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.
