Sentinel-1 is the first of the Copernicus Programme satellite constellations conducted by the European Space Agency. [4] The mission was originally composed of a constellation of two satellites, Sentinel-1A and Sentinel-1B , which shared the same orbital plane.
Sentinel-1A is a European radar imaging satellite launched in 2014. It is the first Sentinel-1 satellite launched as part of the European Union's Copernicus programme. The satellite carries a C-band Synthetic Aperture Radar which will provide images in all light and weather conditions. It analyzes many phenomena occurring on Earth, from ...
Return to flight for Vega-C following the VV22 launch failure. Third Sentinel-1 satellite. Originally intended to launch on the Russian Soyuz launch vehicle; due to geopolitical factors, ESA moved Sentinel-1C to a Vega-C launch. 6 December 03:14 [242] [243] Simorgh: Semnan LP-2: ISA: Saman-1: ISA: Low Earth: Space tug: In orbit: Operational ...
Sentinel-1B was a European radar imaging satellite launched on 25 April 2016. It is the second of two original satellites in the Sentinel-1 constellation, part of the European Union's Copernicus programme on Earth observation. The satellite carries a C-SAR sensor, capable of providing high-resolution imagery regardless of weather conditions.
Copernicus is the Earth observation component of the European Union Space Programme, managed by the European Commission and implemented in partnership with the EU member states, the European Space Agency (ESA), the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), the European Centre for Medium-Range Weather Forecasts (ECMWF), the Joint Research Centre (JRC ...
The launch of the first satellite, Sentinel-2A, occurred 23 June 2015 at 01:52 UTC on a Vega launch vehicle. [7] Sentinel-2B was launched on 7 March 2017 at 01:49 UTC, [8] also aboard a Vega rocket. [2] Sentinel-2C was launched on 5 September 2024 on the last [9] Vega launch vehicle. [10]
Sentinel-2B is a European optical imaging satellite that was launched on 7 March 2017. It is the second Sentinel-2 satellite launched as part of the European Space Agency 's Copernicus Programme , and with its orbit phased 180° against its sister satellite, Sentinel-2A .
ERS-1 had various mission phases using 3-day and 35-day repeat cycles. During the geodetic mission, ERS-1 was put in two long repeat cycles of 168 days, which is equivalent to a single 336-day cycle. The geodetic mission allowed for accurate mapping of the Earth's bathymetry and geoid over the seas using the Radar Altimeter.
