Transcription

1 S-Band TTCET Ground Station

2 Main Performances Reception frequency range : S Band: 2200 to 2300 MHz Downlink Budget G/T S band : > 10 db/ 10 of elevation in whole Bandwidth Emission frequency range : S Band: 2020 to 2120 MHz Emission level: 50 dbw in whole Bandwidth Visibility : from 5 Elevation Pointing accuracy: < 0,20 in Program track, AA SYSTEL - p.2

3 S-Band TTCET Parabolic antenna: Ø3.1 meters (10.17 Feet) Azimuth / Elevation pedestal with dedicated pointing strategy for Zenithal passes. Designed for LEO Satellites Operations Automatic and Unmanned Station Operational Wind-Speed: > 200 Km/h (124 Mph) with provided radome Operational Temperature: -40 C / +60 C with radome and suited air-conditioning unit Low consumption system < 6 KW AA SYSTEL - p.3

4 Main Features Reception, demodulation and data transfer of S- Band (RHCP and LHCP) Telemetry: Simultaneous emission and reception in S band, S-Band selectable (RHCP or LHCP) Telecommand Tracking Capabilities Program Track (CNES pointing Files format) Multi-mission Station (designed for tracking several satellites and several passes per day) Permanent Remote Monitoring status Built-in Satellite Control Center interface Real time recording of station activity : Logbook. AA SYSTEL - p.4

9 Options Earth Terminal Test Equipment Manual bench test designed to check the performances of the station and enables an easy maintenance. GenRec Digital data stream generator from binary files or digital data stream Telemetry or Telecommand recorder. Be easily installed on a Ground Station Telemetry or Telecommand chain thanks to the input connector which duplicates the input signal towards an output auxiliary connector. Service contracts Technical Visits On site assistance (LEOP Support, Training, ) Technical support SLE gateway (ESA licence). AA SYSTEL - p.9

10 This station has been installed at: ASAL (Algeria) 2 stations CNES (France) 2 stations EUMETSAT (Germany) 2 stations INPE (Brasil) Ministry Of Defense (France) 2 stations SSC (Sweden) AA SYSTEL - p.10.

11 Significant Heritage More than 10 satellites daily operated JASON-1, DEMETER, ESSAIM (4 Microsatellites out of service since end of 2010), PARASOL, COROT, CALIPSO, JASON-2, SMOS. and soon: ALSAT-2, ELISA, JASON 3, PICARD and TARANIS with installed stations basis AA SYSTEL - p.11 T

12 Robust Design and High Availability Figures Mean Time Between Failure > Hours Based on 3 passes per day with a pass duration of 20 Minutes each. A station designed for 95% of availability but availability processed from past experience is better >99% (with spare parts collocated to the station). Identical software version for all S-Band stations under Windows 2003 server. This robust software continuously maintained contributes to the high availability of the station. AA SYSTEL- p.12

13 More than 10 satellites daily operated SIGNIFICANT HERITAGE & QUALIFICATION EASY MAINTENANCE AND LOW OWNERSHIP COST AUTOMATIC & REMOTE FUNCTIONS OPERATIONAL UNDER ALL WEATHER CONDITIONS DESIGN FOR MULTIMISSION HIGH AVAILABILITY AA SYSTEL - p.13
