DLR Webcast: Interview with Marwan Younis at IGARSS 2012

DLR Webcast: Interview with Marwan Younis at IGARSS 2012

We are still here at IGARSS, giving you more information about 'Remote Sensing for a Dynamic Earth'. We spoke with Marwan Younis, who took some time from an incredibly tight schedule to answer some questions regarding TerraSAR-X and TanDEM-X, as well as Synthetic Aperture Radar (SAR) technologies. read more

Congratulations! DLR experts receive IEEE award

Congratulations! DLR experts receive IEEE award

DLR scientists had reason to celebrate one month ago – the successful TerraSAR-X mission celebrated its fifth anniversary in space. Today, on 23 July, during the Plenary Session at the International Geoscience and Remote Sensing Symposium (IGARSS 2012) in Munich, the hard work of DLR experts involved in the radar satellite TanDEM-X mission has been recognised. Our DLR colleagues were awarded with the ‘IEEE WRG Baker Paper Award’. This award is given annually to scientists who accomplish extraordinary achievements in the field of electrical engineering and computer science. read more

Observing Earth from space - IGARSS 2012

IGARSS 2012

The countdown to the International Geoscience and Remote Sensing Symposium IGARSS 2012, has begun - only 6 days remain. This year, IGARSS will be held at the International Congress Centre in Munich from 22-27 July, and with this blog, we will be reporting on all the breaking announcements and important events. We will do this with written entries, images and webcasts - in which specialists in Earth observation and remote sensing will join us. read more

Where and how does ice move in the ocean?

TanDEM-X has now begun routine operations, and is working with TerraSAR-X in bistatic mode and recording data for its global digital terrain model. In this post, I look back at an earlier phase of the mission, when this satellite pair orbited the Earth separated by a mere three seconds or 20 kilometres, and each sensor acquired images independently. read more

Traffic monitoring with the TerraSAR-X/TanDEM-X satellite constellation

Traffic monitoring from space, day and night, from more than 500 kilometres up above; is that possible? Indeed it is! In fact, it has been demonstrated several times in the past – once with the Shuttle Radar Topography Mission (SRTM), and again with TerraSAR-X. The traffic processors used with SRTM and TerraSAR-X were and are still subject to considerable limitations. read more

Baptism of fire for the satellite formation

Last Thursday, the two German radar satellites of the TanDEM-X formation finally reached their operational orbit configuration, with only a few hundred metres separating them. In this configuration, they act as a unique radar interferometer in space. The next day, on Friday evening, the instruments were switched on, after many careful checks, to acquire the world's first Digital Elevation Model (DEM) data using a free-flying bistatic Synthetic Aperture Radar (SAR) satellite formation. That same night, the jointly acquired data were received and processed by our operational processing chain. read more

The satellites have 'eye contact'

This is the moment we have been anticipating for a long time; TerraSAR-X and TanDEM-X finally have 'eye contact'. The final manoeuvre to adjust the close formation was performed on 13 October. Now, the two satellites are orbiting at a distance of less than 400 metres from one another. read more

"Everybody waltz!"

Umlaufbahnen der Radarsatelliten

"Everybody waltz!" – this is the invitation to dance at the annual Vienna Opera Ball. This phrase is now applicable to the TerraSAR-X and TanDEM-X satellites, because as of yesterday the 'dance floor' is open and close formation flight has begun. Upon successful completion of the final tests, permission to commence the now imminent mission phase was granted by a panel of experts at the conclusion of the Formation Flight Reviews. read more

TerraSAR-X and TanDEM-X 'chatting' for the first time

Brasília

Even though the 'chit chat' between the satellites has so far consisted of no more than the exchange of synchronisation signals – "Hello, here I am!" – that is been all that was needed for the first simultaneous imagery to be captured by TerraSAR-X and TanDEM-X. Since 22 July 2010, TerraSAR-X has been flying ahead of TanDEM-X at a distance of just 20 kilometres, in a formation defined for test purposes and which also affords scope for a special series of radar experiments. They have now completed the first ever experiment with bistatic radar involving two satellites flying together in formation. read more

The face of the Earth

For a month now, we have been acquiring altitude models with the TanDEM-X and TerraSAR-X satellite pair. Already, over 1000 products have come out of our operational processing chain. Alongside many test images, some of the data also give an insight into how humankind has shaped the surface of the Earth – and how the highs and lows around them have determined the course of their lives. read more
