Objectives
The main goal of the activity is to provide Telecom and Navigation Mission operators, project teams, development engineers and scientists with a completely operational prototype capable of supplying, in a structured manner, information on the space environment and its effects on the spacecraft.
This information will contribute to the satellite maintenance (fully operational) to fullfil the mission requirements and finally improve the system and future similar systems by applying a "Lesson Learned" philosophy. This prototype will set the basis of the future Space Environment Support System for Telecom and Navigation Missions – SESS.
In order to be able to give Space Environment support to the users SESS is provided with a set of main capabilities. These capabilities are:
- Ingestion of environment and effects Data
- Processing, classification and storage of Data
- Space Environment (SE) / Space Weather (SW) and Satellite Effects Monitoring
- Space Environment (SE) / Space Weather (SW) Forecasting
- Satellite operators specific products and tools
- Compliant with a "Lessons Learned" philosophy
Challenges
The main topics addressed to SESS project are:
- Review the Space Environment Effects and Sensitive Parts on Telecom and Navigation satellites.
- Identify satellite housekeeping data needed to perform Space Environment effects monitoring.
- Review the satellite System, Subsystems and units data available related SE effects.
- Review the procedures for on board anomaly responses.
- Review and identification of Telecom and Navigation MCC requirements related to SE.
- Identify possible SE data sources to be used for SESS purposes.
- Identify the SESS Space Environment, Satellite anomalies database
- Space Environment data, models and tools definition.
- SE and Effects databases definition
- SESS external interfaces analysis.
Plan
The study tasks are:
Task 1: "Analysis of the Telecom and Navigation Space Segment"
Task 2: "Analysis of Telecom and Navigation Mission Control Centre"
Task 3: "SESS System Requirements Analysis and Design"
Task 4: "SESS Implementation"
Task 5: "SESS Integration, Testing, Validation and Installation"
The delivery of SESS has to be performed at T0 (1st August 2005) + 1 year.
Finally,
Task 6: "Environment Characterisation", which shall maintain the SESS system during two years of operations.
Current Status
The Kick Off was held on 1st August 2005.
The SESS team is analysing Nav/Tel Space Segment and Mission Control Centre, whose main objective are respectively to conduct an analysis of space environment sensitive parts and subsystems and to derive Nav/Tel MCC requirements for the Space Environment Data, models, tools and databases
