Mobotix cameras celebrate their tenth year at a German Antarctic research station

Company’s cameras monitor radio telescope at site to ensure its functioning properly


Winnweiler/Langmeil, Germany, 6 February 2012. Winter temperatures of down to -65°C, raging storms with wind speeds of more than 250 km/h and millions of penguins – this is Antarctica. This is where O'Higgins, the German Antarctic Receiving Station, is located. It was founded in 1991 by the German Aerospace Center and the German Federal Agency for Cartography and Geodesy to collect data from geographical satellites and stars. MOBOTIX cameras monitor the radio telescope to make sure that it continues to function properly – and these cameras are now in their tenth year. It all started with the M1 model, and now four M12 cameras and one M10 camera are in use. No problems have been recorded so far – even under the world's most extreme weather conditions. The advantage of the MOBOTIX solution: The cameras work without heating or ventilation and consume only three to four watts of electricity. They can also be installed in areas where power is rare. A traditional camera with heating would consume around 40 watts, making it unsuitable for use under these conditions. The decentralized processing and storage in the MOBOTIX camera also reduce the required bandwidth to a minimum and significantly cut system costs. The PC or the video control center is required only to view and control the cameras (PTZ), but not to evaluate and record.

A Clear Picture In Spite Of Icy Temperatures

For the German Antarctic Receiving Station, it is extremely important to ensure that the radio telescope is working properly. For this reason, the telescope was initially monitored with an analog camera, but the camera was only able to deliver good results when there was sufficient light and visibility. The switch to the M1 from MOBOTIX in 2003 meant an investment in a digital outdoor system. The camera was installed at a sheltered spot of the station's outside wall where it has to resist temperatures ranging from +10°C down to -30°C – and sometimes lower – as well as storms with wind speeds of up to 250 km/h. The camera is integrated into the station's LAN and provides real-time images on this subnet. In order to save transfer capacity, current images are sent about every ten minutes via satellite to the Internet. Over the course of the years, the system was expanded to include additional MOBOTIX cameras: two cameras monitor the area around the station and two additional cameras film the penguins who regularly come to visit (webcams: http://ivs.bkg.bund.de/vlbi/ohiggins/ – select Webcam/Images: Photos).

The station is regularly equipped with the newest camera models. This way, the cameras can continue to work perfectly in spite of the extreme weather conditions. "Since the camer as were installed, we have been able to maintain first-class eye contact with the radio telescope and, thus monitor its position continuously," reports computer scientist Reiner Wojdziak, who spends several months in Antarctica each year. "We are absolutely satisfied with this solution."

Parade Of The Penguins

The radio telescope is not the only thing the camera monitors. Penguins regularly come waddling in front of the antenna as well. They are welcome guests for the scientists and even have their own Internet fan community (see http://www.martingrund.de/pinguine/index.htm and http://ivs.bkg.bund.de/vlbi/ohiggin s/ – Images see: Photos/Penguins). Thanks to the penguins, the MOBOTIX M10 is now the first animal webcam in Antarctica.
