RE: SAR-Lupe 2 Satellite
Permalink  
 

The second satellite in the SAR-Lupe system has been placed successfully in orbit. The Russian Cosmos 3M launch vehicle lifted off last night from the Russian Plesetsk space centre, south of Archangelsk, on schedule at 21:38:41 hours CEST. Roughly half an hour later, it released the radar satellite into its low-earth orbit at an altitude of roughly 500 km.

The first sign of life from the satellite was picked up by the ground station Kerguelen in the Southern Indian Ocean at 22:41 hours, with direct contact established between the control centre and the satellite as planned 92 min. after launch. Preliminary testing indicates that SAR-Lupe 2 is working perfectly in its orbit. Accordingly, work commenced last night on putting the satellite in operation. In a preliminary highlight, the antenna boom was deployed.
Satellite control is currently in the hands of the German Space Agency DLR in Oberpfaffenhofen. The ground station of the German Armed Forces in Gelsdorf is tracking the satellite at the same time and will assume operative responsibility for it at the end of July, at which point in time it will start collecting SAR radar images.
The German Armed Forces are already able to use the system. With the second launch and ensuing ramp-up of the satellite, the German Federal Armed Forces will have an operational reconnaissance system as of autumn 2007.
The first SAR-Lupe satellite has been in orbit since December 2006. It is supplying superb high-resolution images and is operating very successfully and reliably.
The remaining three satellites will be launched in intervals of around four months, with the entire system to be completed in 2008.

The launch of  the Russian carrier rocket "Kosmos-3M", which was set to be launched late on  Sunday evening  to  put into orbit the German satellite SAR- Lupe, was rescheduled by 24 hrs because of  unfavourable meteorological conditions.

"launching is postponed  today  because of meteorological conditions - at an altitude of 143 kilometres  wind speeds exceed maximum permissible" - Aleksey zolotukhin, chief of  information, space troops.

The launch of the second German radar reconnaissance satellite in the SAR-Lupe system has been scheduled for the evening of July 1, 2007. Like its predecessor, it will be launched into its low-earth orbit from the Russian Plesetsk Cosmodrome onboard a Kosmos 3M  rocket.
Launch is scheduled for  19:38 GMT (3:38 p.m. EDT).

The Russian Kosmos 3M rocket will place the 770kg SAR-Lupe 2 spacecraft into a 500 km high Polar orbit.
The remaining three satellites are to be launched in intervals of around four months, with the entire system to be completed in 2008.
The spacecrafts have a lifespan of around 10 years.

The SAR-Lupe radar reconnaissance spacecraft - the first german military satellite - feature a synthetic aperture radar (SAR), which will have a spatial resolution of less than 1 metre. Due to the intelligent combination of existing technologies, SAR-Lupe operates independently of weather conditions on a 7/24 basis.
