Pleiades-hr Image Quality Commissioning
PLEIADES is the highest resolution civilian earth observing system ever developed in Europe. This imagery program is conducted by the French National Space Agency, CNES. It operates since 2012 a first satellite PLEIADES-HR launched on 2011 December 17th, a second one should be launched by the end of the year. Each satellite is designed to provide optical 70 cm resolution coloured images to civi...
متن کاملPleiades-hr Innovative Techniques for Geometric Image Quality Commissioning
Since the beginning of 2012, the first Pleiades-HR satellite of the program conducted by the French National Space Agency, CNES, delivers 20 km wide color scenes with a 70 cm ground sampling distance. A second satellite should be launched in 2013 which will achieve an almost world-wide coverage with a revisit interval of 24h. The assessment of the image quality and the calibration operation hav...
متن کاملPleiades-hr Innovative Techniques for Radiometric Image Quality Commissioning
The first Pleiades-HR satellite, part of a constellation of two, has been launched on December 17, 2011. This satellite produces high resolution optical images. In order to achieve good image quality, Pleiades-HR should first undergo an important 6 month commissioning phase period. This phase consists in calibrating and assessing the radiometric and geometric image quality to offer the best ima...
متن کاملUsing Exotic Guidance for Pleiades-hr Image Quality Calibration
In-flight Image Quality calibration and performance assessment activities depend on specific acquisitions and, for some of them, on dedicated guidance of the satellite platform. The operational constraints may be tedious during the commissioning phase. Moreover, the length of the requested data collection may be conditioned by uncontrolled parameters such as climatic hazard. The new French high...
متن کاملImproving Image Quality in Remote Sensing Satellites using Channel Coding
Among other factors that characterize satellite communication channels is their high bit error rate. We present a system for still image transmission over noisy satellite channels. The system couples image compression together with error control codes to improve the received image quality while maintaining its bandwidth requirements. The proposed system is tested using a high resolution satelli...
