AWS
Arctic Weather Satellite
| ESA / EUMETSAT | Approved | Jun 2024 | Jun 2029 | AWS is the protoflight satellite for a planned constellation of meteorological microsatellites providing passive microwave soundings for global atmospheric temperature temperature and humidity profiles soundings in all weather conditions, with frequent revisits over the Arctic and Antarctic polar regions. This constellation (called EPS-Sterna, which is named after the latin name Sterna for the Arctic Tern) will consist of 3 orbital planes with 2 satellites in each orbital plane. With a nominal satellite lifetime of 5 years, a first launch in 2029 and 2 replenishments of each orbit plane, a minimum mission lifetime for the full system of 13 years will be achieved. Local Solar time for AWS is 09:00 - 11:00 and EPS-Sterna Descending LST is 03:30, 07:30, 11:30. | AWS Instrument | Type: Sun-synchronous
