These satellites should be designed to provide low-cost local PC reception through the use of common data transmission protocols and the adoption of an Open Systems Approach towards application development. Establishment of such a network through multiple national contributions in Europe could transform the EO into a dynamic, productive and sustainable industry. These satellites observe the Earth from a LEO orbit with a resolution of 30 meters, four spectral bands, and a swath width of 350 km. This ensures global one-day coverage.
Requirements show that local decision-makers demand high temporal resolution.
High spatial and spectral resolution should not be the primary drivers. It allows the local decision-maker to collect data independently, without interference by the satellite operator, large central data processing and distribution entities or other administrative bodies. This paper assesses the user needs and requirements. These needs and requirements were conceived from local civil society managers both in developed and developing countries. The key sub-systems of the satellite, the satellite sensor and the ground segment are highlighted in this paper.
