AbstractThis paper presents a method for deriving the snowline altitude using a combined analysis of terrain elevation and multispectral Advanced Wide Field Sensor (AWiFS) data from the RESOURCESAT-1 satellite, launched by India on 17 October 2003. AWiFS is a unique instrument capable of acquiring imagery of the world repeatedly every 5 days with very high radiometric resolution. It provides a wide swath width, which is very useful for snow-cover mapping. Snowline altitude is a good indicator of snow coverage. Snowline altitude for the period from October 2004 to June 2005, and from October 2006 to June 2007, is determined for the Baspa Basin, which is located in the Kinnaur district of Himachal Pradesh, India. It is observed that snowline altitude is generally higher during the year 2006/07 than during 2004/05, except in December 2006 and March 2007. The results obtained with the analysis presented here are validated using available meteorological data and are found to be satisfactory. This thus establishes a method that can be applied to other terrains and over longer periods of time within the coverage of the AWiFS sensor data.

Infrared weak small target detection is one of the key technologies in the early infrared imaging guidance and wide-field view surveillance system. In the complex and low signal-to-noise ratio background, the target has only a few pixels. There is no shape and texture information to use. It brings great difficulties to the infrared weak small target detection. In this paper, we sum up the research status of infrared weak small target detection method, and analyze the key problems of infrared weak small targets detection.

The Automated Transfer Vehicle (ATV) “Jules Verne” is the first completely automated rendezvous and docking spaceship to service to the International Space Station (ISS). As a cargo ship, it is designed for one-time use. After completing its mission, it is subjected to hypersonic flow during the re-entry into earth’s atmosphere, with high associated heat flux leading to structural heating and fragmentation of the vehicle. During its first voyage on September 29, 2008, the ATV reentry was observed using various instruments including a wide field view camera and high frame rate cameras. Using the wide field view camera the trajectory path can be reconstructed. The high frame rate camera gives information about the sequence of the events of the explosions and fragmentations of various parts of the spacecraft. The aim of this paper is to present the detailed events that occurred during the ATV re-entry.
