7. X-band SAR Systems SAR-Lupe (Germany) (a) Constellation of five radar satellites placed in orbit in Dec. 2006; July & Nov. 2007; March & July 2008 for German military using Russian Cosmos-3M launchers from Plesetsk. (b) Three different orbital planes are being used – Plane 1 contains 2 satellites; Plane 2 has 1 satellite; and Plane 3 has 2 satellites. (c) Characteristics :- Medium weight – 770 kg Orbital altitude – 500 km Ground coverage – 80 ° N to 80 ° S latitude Ground Sampled Distance (GSD) - <1 m
8. X-band SAR Systems SAR-Lupe (Germany) (a) Satellite platform – OHB-System (Bremen) (b) Parabolic antenna (3 m) – Saab-Ericsson (c) Satellite control system – Integral Systems (d) Satellite ground control station is located at Gelsdorf, near Bonn. Military operated. (e) Ground segment – EADS Astrium (i) Each satellite has a fixed antenna (ii) When satellite is pointing in a fixed direction, it gives stripSAR imagery. (iii) If satellite is rotated to point at a specific area it gives a spotlight image.
9. X-band SAR Systems TerraSAR-X (Germany) ( a) Satellite was launched by Russian Dnepr rocket from Baikonur in June 2007. (b) Large satellite – 1,230 kg (c) Orbital altitude – 514.8 km (d) Ground coverage – 82 ° N to 82 ° S Latitude Public/Private Partnership (PPP) between DLR and EADS Astrium. DLR owns the satellite. Astrium built the satellite and the SAR. Infoterra has commercial rights to the imagery. Cost – 130 million Euros (satellite); 55 million Euros (ground segment) Ground Receiving Station – Neustrelitz (DLR) GSD values – 1m ( Spotlight – 5 x 10 km area); 3m ( StripSAR – 30 km swath); 18m ( ScanSAR – 100 km swath)
