Second International Workshop on On-Board Payload Data Compression, Toulouse, France
28 October 2010 - 28 October 2010
France
The Second International Workshop on On-Board Payload Data Compression will be held on 28 and 29 October 2010 in Toulouse, France.
Next generation instruments to be carried on-board spacecraft are collecting a large quantity of information at increasing rate, due to the recent technological improvements. The huge amount of data generated on-board, is competing with the limited channel resources available for the transmission of data on-ground. The result of this scenario is the increasing importance that on-board payload data compression is gaining in the framework of a spacecraft design.
In remote sensing systems, a major problem lies in the limited availability of bandwidth and resources necessary for acquisition, processing and transmission of the images related to a given terrestrial area, as acquired by the sensors mounted on an airborne or spaceborne remote platform. Since the spatial, spectral and radiometric resolutions of optical and radar sensors are getting finer and finer, the amount of collected data is huge. New-generation sensors aim at increasing the resolution even further. Because of the huge amount of data, powerful compression algorithms are required to match the available channel resources. Moreover, many Earth Observation satellites are required to transmit data on-ground in real time, this means that compression devices with very high throughput are requested.
In science missions, one of the challenges is to have the capability to transmit to the ground stations a high amount of data through a limited downlink. GAIA, the new astrometric mission of the European Space Agency, is facing this challenge. With a scheduled launch in 2011, GAIA will observe more than one billion stars and other objects with unprecedented accuracy. Such a mission implies large technological and design efforts, since it will have to detect, select and measure hundreds of stars every second, while sending their data to the Earth. Thanks to on-board data compression, it will be possible to transmit all the data generated on-board, without any restriction, allowing maximizing the science return.
The event will aim to bring together all the professionals working in the field, to share the latest ideas and developments and to pave the way for the future technological challenges.For further information, please visit:
