TerraSAR-X
2007-026A
X band imaging satellite built by Astrium for DLR; it is a joint EADS Astrium/DLR project.
TerraSAR-X is a cylinder 2.3 dia and 5.2m long with mass of 1346 kg, with 1 X-band antenna 4.8m long and 0.8m wide. Orbit 514 x 514 x 97.4. The Dnepr used a 1.5m fairing extension for the first time in its Yuzhnoe/Yuzhmash fairing. Control from GSOC Operpfaffenhofen via Weilheim and Neustrelitz ground stations. Ground res. is 1 meter. Control from GSOC.
The satellite was placed in a 499 x 512 km orbit, later adjusted to 507 x 509 km. The plume shield was in a 481 x 511 km orbit, and the final stage was in a 507 x 1024 km orbit.
A piggyback experiment was attached to the final stage of the Dnepr, including a TV camera to record payload separation.
