Payload Data Ground Segment in Cloud for Earth Observation Satellites with the Entice Middleware

Becedas, Jonathan; Núñez, María del Mar; Gonzalez, David

 

 In this work we implemented in cloud the Payload Data Ground Segment (PDGS) of the gs4EO commercial software, created by Deimos Elecnor Group. This pilot implementation is named EOD Pilot (Earth Observation Data Pilot). The advantages of the EOD Pilot with regards to a traditional PDGS are the following: optimized ingestion and processing of raw data incoming from ground stations, on-demand adaptation of the infrastructure for processing incoming data, provisioning of an optimized storage service for cataloguing, reduction of the delivery time of products to end users, data rate optimization between the Virtual Machines (VMs), VM startup and auto-scaling optimization. The implementation was done by using the ENTICE middleware, maintaining all the functionalities of the system and improving efficiency, agility and extensibility. The final results of system are shown.
