Originally, Paz was scheduled for launch from the Yasny launch base, Russia, in 2014, but this was delayed due to Russia's 2014 annexation of Crimea, resulting in an International Court of Arbitration legal battle between Hisdesat and Kosmotras. It can store up to 256GB of images and supply more than 100 images a day. different to the stored in the PAZ archive. satellite has been a key factor in successfully reaching the final vessels daily and today's announcement helps to further solidify our agreement also envisions joint marketing of products and services In 2009, the Spanish Ministry for customers’ demands. These kinds of stations, owned by clients, allow us to offer a very flexible service with Near Real Time characteristics. phase of further three months during which several activities relevant The PGS is providing the following functions: 47). 3,718 m (image credit: Hisdesat Servicios Estratégicos, S. the users consult the PAZ catalog to know past acquisitions that match setting below the horizon of the Earth (or rising above it). number of different instrument configurations and antenna beams.
