ESA agrees prototype development for Arctic Weather Satellite mission The European Space Agency (ESA) has signed a contract with OHB Sweden to be the prime contractor for the development of its Arctic Weather Satellite (AWS) Programme. The contract, with a total value of €32.5m euros, includes the development of the satellite (including its instrument), the development of the ground segment and also the preparation activities for a possible AWS constellation. The AWS consists of a single satellite, which is the prototype for a possible future constellation of AWS satellites. It will be equipped with a payload specifically designed to provide global measurements of the atmosphere to enhance weather predictions (in particular over the Arctic).
