sentinel 3b launch date

[6], The applications of Sentinel-3 are diverse. Flying in the same orbit with a separation of 140°, the pairing of the Sentinel-3 satellites extends the coverage and data delivery for the European Commission’s Copernicus programme with the objective to observe the Earth. The pairing of the two satellites optimises coverage and data delivery for Copernicus. Sentinel-3B will join its twin, Sentinel-3A, in orbit to systematically monitor Earth’s oceans, land, ice and atmosphere. Copernicus relies on the Sentinels and contributing missions to provide data for monitoring the environment and for supporting civil security activities. Copernicus, formerly Global Monitoring for Environment and Security, is the European programme to establish a European capacity for Earth observation designed to provide European policy makers and public authorities with accurate and timely information to better manage the environment, and to understand and mitigate the effects of climate change. [10], Sentinel-3A was subsequently launched on 16 February 2016 on a Rokot vehicle from the Plesetsk Cosmodrome, located near Arkhangelsk, Russia. Sentinel-3 is a dedicated Copernicus satellite mission delivering a variety of high-quality ocean measurements. The Sentinel-3B satellite has been at the cosmodrome since mid-March being readied for its ride into space on 25 April at 17:57 GMT (19:57 CEST).

The Sentinel-3 mission is essential for applications for ocean and coastal monitoring, numerical weather and ocean prediction, sea-level change and sea-surface topography monitoring, ocean primary production estimation and land-cover change mapping. This pairing of satellites increases coverage and data delivery for the European Union’s Copernicus environment programme.

Operational lifepsan: “It also offers lots of opportunities for commercial companies to develop new innovative services.
This sensor can then be used to by researches to do water quality and land-monitoring research. This includes monitoring the health of the satellite and the instruments, and coordinates housekeeping telemetry and commands at the main flight control center in Darmstadt, Germany. Following instruments are carried by the satellites: The Ocean and land colour instrument (OLCI) features 21 distinct bands between 400 and 1020nm wave length and with that has equivalent precision as the former MERIS instrument (15 bands).

Repeat Cycle: 27 days. The SRAL instrument is supported by a microwave radiometer (MWR) that performs atmospheric corrections and by three more instruments (GNSS – Global Navigation Satellite Sytsem, LRR – Laser Refrectometer and DORIS – Doppler Orbitography and Radiopositioning Integrated by Satellite) to determine the position in orbit at an accuracy of 3cm. Esa maintain a backup flight control center at a ground station in Kiruna, Sweden. Flying in the same orbit with a separation of 140°, the pairing of the Sentinel-3 satellites extends the coverage and data delivery for the European Commission’s Copernicus programme with the objective to observe the Earth. Two weeks after its launch the first image was captured on 7 May 2018 showing a sunset scene over Weddell Sea in Antarctica. Over oceans, it measures the temperature, colour and height of the sea surface as well as the thickness of sea ice. Its numerous bands will be used to monitor aquatic biological productivity, marine pollution, the health of vegetation over land and land use changes. Many European companies are involved in supplying the SLSTR instrument, including SELEX Galileo, RAL (Rutherford Appleton Laboratory), Jena-Optronik, Thales Alenia Space, ABSL and ESA-ESTEC. Sentinel-3A is a European Space Agency Earth observation satellite dedicated to oceanography which launched on 16 February 2016. Sentinel-3B was successfully launched on 25 April 2018 at 17:57 UTC from the Plesetsk Cosmodrome aboard a Rokot launch vehicle. The Sentinel-3 mission is designed to observe the oceans, changes over land, ice and the atmosphere. The instrument will be particularly used to measure the height of rivers and lakes, surface wind speed, sea ice height and thickness. The Sentinel-3B and Sentinel-3A ensure the monitoring and understanding of large-scale global dynamics. The Sea and Land Surface Temperature Radiometer (SLSTR) determines the surface temperature at a precision of < 0,3K (Kelvin). Freshwater is vital to life – but a growing global population, economic development and the effects of climate change are putting mounting pressure on this precious finite resource.

LRR will be used to accurately locate the satellite in orbit using a laser ranging system. [11][12] This first launch was followed by the launch of Sentinel-3B on 25 April 2018, also aboard a Rokot. [4][6][5] Sentinel-3 builds directly on the heritage pioneered by ERS-2 and Envisat satellites. The Sentinel-3 satellites were built by the French-Italian aerospace manufacturer Thales Alenica Space and belong to the European Commission. With the European Master in Geospatial Technologies I continue on a larger scale and find myself highly comfortable with this complete outsight on what surrounds us here and there.

The second Copernicus Sentinel-3 satellite, Sentinel-3B, was launched on 25 April 2018 to join its twin satellite Sentinel-3A in orbit. A radar altimeter (SRAL for Sentinel-3 Ku/C Radar Altimeter) measures the distance from the sensor to the surface at a low resolution (applied for homogeneous ocean surfaces) and at high resolution for ice applications. “This is the seventh launch of a Sentinel satellite in the last four years. Sentinel-3B constitutes the 7th satellite of the Sentinel mission. [8] The satellite platform was delivered to France for final integration in 2013.

The CSC is an earth observation program run by the ESA with the objective of providing high quality continuous monitoring of the earth. We took advantage to say “hello” on the voice loop from the MIK and from the MCC, both tests were successful. The instrument features 9 spectral bands. Launch vehicle: Rockot (Sentinel-3A and -3B) Operator: EUMETSAT. The Copernicus Sentinel-3 mission captured the multiple bushfires burning across Australia's east coast. [7] Bruno Berruti led the team that was responsible for delivering the Copernicus Sentinel-3 satellites from the drawing board into orbit. Sentinel-3 makes use of multiple sensing instruments to accomplish its objectives; SLSTR (Sea and Land Surface Temperature Radiometer), OLCI (Ocean and Land Colour Instrument), SRAL (SAR Altimeter), DORIS, and MWR (Microwave Radiometer). The MWR sensor has a radiometric accuracy of 3.0 K (3.0 °C; 5.4 °F). The mission's main objective in support to the Marine Environment is to determine parameters such as sea-surface topography, sea-surface temperature and ocean-surface colour. The mission provides data continuity for the ERS, Envisat and SPOT satellites. © 2020 European Space Agency. The next Sentinel satellite for Europe’s environmental monitoring Copernicus programme is poised for liftoff from the Plesetsk cosmodrome in northern Russia. Launch vehicle details.

“We have reached this point thanks to dedication and hard work from teams at ESA, the EC, Eumetsat, France’s CNES space agency, industry, service providers and data users. The revisiting time for the SLSTR instrument is less than one day at the equator. Orbit Height: 814 km In addition to the observation instruments, the Sentinel-3 spacecraft will carry the GNSS (Global Navigation Satellite System) and LRR (Laser Retro Reflector) instruments. After being sealed from view in the rocket fairing last week, it was rolled out to the launch pad and hoisted into the launch tower at the weekend. A Eurockot Launch Services Rockot rocket launched the Sentinel-3B mission on Wednesday, April 25, 2018 at 5:57 PM (UTC).
Near-real time data will be provided for ocean forecasting, sea-ice charting, and maritime safety services on the state of the ocean surface, including surface temperature, marine ecosystems, water quality and pollution monitoring. The Sentinel-3B satellite has been at the cosmodrome since mid-March being readied for its ride into space on 25 April at 17:57 GMT (19:57 CEST).

Just 92 minutes after liftoff, Sentinel-3B sent its first signals to the Kiruna station in Sweden. 7 years (With consumables for 12), Orbit Type: Sun-synchronous After being sealed from view in the rocket fairing last week, it was rolled out to the launch pad and hoisted into the launch tower at the weekend. While these data are fed primarily into the Copernicus Marine Environment Monitoring Service, all the Copernicus services benefit to produce knowledge and information products in near-real time for a wide range of applications. For me, the geo-world holds a high potential to learn and create life. It is a clear demonstration of what European cooperation can achieve and it is another piece to operating the largest Earth observation programme in the world, together with our partners from the European Commission and Eumetsat,” said ESA Director General Jan Wörner. The satellite launch services contract for Sentinel-3B was awarded to Eurockot Launch Services.

[24], The observations acquired by the mission will be used to in conjunction with other ocean-observing missions to contribute to the Global Ocean Observing System (GOOS) which aims to create a permanent system of ocean observation. All Rights Reserved. Sentinel-3 also had the ability to detect changes in sea-surface height and sea-ice using the synthetic aperture radar altimeter and the microwave radiometer, two of the most complex sensors on the satellite. I am glad to see this has become reality and that it is now a large European success story.”. Vega successfully delivered Sentinel-2B on March 7, 2017. Two more satellites, Sentinel-3C and Sentinel-3D, are on order. Eurockot and Arianespace are contracted to launch the spacecraft. In parallel, in ESOC, the last LEOP nominal simulation took place with the B team on console. Sentinel-3 is primarily an ocean mission, however, the mission is also able to provide atmospheric and land applications. Ferocious bushfires have been sweeping across Australia since September, fuelled by record-breaking temperatures, drought and wind. [11] The satellite orbit provides a 27-day repeat for the topography package, with a 4-day sub-cycle. Data links were quickly established by teams at ESA’s operations centre in Darmstadt, Germany, allowing them to assume control of the satellite. The Ocean and Land Color Instrument (OLCI) has a 300 m (980 ft) resolution with 21 distinct bands allowing global coverage in less than four days. It was built as a part of the Copernicus Programme, and is the first of four planned Sentinel-3 satellites. The dimensions of the craft are: 3.7 x 2.2 x 2.2 m with a weight (at time of launch) of 1250 kg. [1] It was built as a part of the Copernicus Programme, and is the second (after Sentinel-3A, launched 16 February 2016) of four planned Sentinel-3 satellites. This station is responsible for receiving the data collected by Sentinel-3. Sentinel-3B was successfully launched on 25 April 2018 at 17:57 UTC from the Plesetsk Cosmodrome aboard a Rokot launch vehicle. The satellite platform was delivered to France for final integration in 2013.
