The second satellite of the Sentinel-2 mission is set for launch on March 7th at 02:49 CET
from Europe’s Spaceport

Sentinel-2B is set for liftoff tonight at 01:49 GMT (02:49 CET) from Europe’s Spaceport near Kourou, in French Guiana, on a Vega rocket. The rocket will deliver the new Earth observation satellite into orbit about an hour later. Once in orbit, the new spacecraft will join its twin, the Sentinel-2A satellite launched in 2015, completing this way the colour vision constellation and doubling the coverage provided by the mission.

As part of the Copernicus programme (formerly GMES), the Sentinel-2 mission has been designed to deliver high-resolution optical images for land services, providing, for example, imagery of vegetation, soil and water cover, inland waterways and coastal areas, as well as information for emergency services. Elecnor Deimos involvement started at the early phases of the mission, undertaking the mission analysis in the GMES Architecture study, has continued during the implementation phase and will extend with the support to its operations.

Elecnor Deimos has been responsible for the development of one of the most critical elements of the Ground Segment, the Mission-Planning System (S2MP). The S2MP is in charge of the Sentinel-2 mission plan generation for imagery acquisition, payload calibration and the associated on-board data management activities and subsequent data downlink activities to ground-stations and/or EDRS.

S2MP is designed to work with multiple operational scenarios in parallel, that can be changed to adapt to new user requests and manual acquisitions or new ground stations scenarios. It incorporates a highly configurable and powerful tool, the Plan Edition Tool (PlanET) which provides an advanced graphical visualization of planned tasks, as well as an improved representation of the on-board resources and the detected conflicts.

The company has also been prime contractor for the Mission Performance Assessment system (S2MPA). This facility is composed of two software components, the Quality Control and Calibration (QCC) and the End-to-End System Performance Monitoring (E2ESPM). The S2MPA-QCC is responsible for quality control and calibration/validation, generating the entire payload on-board and on-ground processing calibration parameters as well as raising alerts for Sentinel-2 products quality defects and mission anomalies. The S2MPA-E2ESPM monitors the Sentinel-2 system operations, analyzing the main business process contributing to the overall Sentinel 2 end-to-end system performance.

In the development of these systems Elecnor Deimos has incorporated elements from the gs4EO suite of products, used operationally in the mission DEIMOS-2, among others. More than 15 Elecnor Deimos engineers have contributed in the last years to make this mission become a reality.
