This paper describes the main characteristics and architecture of a satellite mobile internet access (MSIA) system developed by ETRI. MSIA system provides Internet service, broadcasting, and digital A/V service in both fixed and mobile environments using Ku-band geostationary earth orbit (GEO) satellite. A Ku -band two-way active phased array antenna installed on top of the transportation vehic...

Severe weather prediction, such as tropical cyclone (TC) forecast is a typical data mining and forecasting problem that involves high level data manipulation and interpretation of meteorological information such as satellite pictures and other meteorological observation data. In this paper, we present a fully automatic and integrated system known as "ATOMOSPHER" Automatic Track Mining and Objec...

The launch of SELENE, which acquired the first direct tracking data over the farside of the Moon by the use of 4-way Doppler data between a relay satellite and the main satellite, has resulted in a dramatic improvement of the knowledge of the global lunar gravity field[1,2]. In addition to the 4-way Doppler data, same-beam differential VLBI data between the two sub-satellites and two stations o...

This contribution reassesses progress in the development of satellite laser ranging (SLR) technology and its scientific and societal applications in South Africa. We first highlight the current global SLR tracking stations within the framework of the International Laser Ranging Service (ILRS) and the artificial satellites currently being tracked by these stations. In particular, the present wor...

against the range-dependent accuracy of the tracking radar measurements including range, elevation and bearing angles, a new hybrid adaptive kalman filter is proposed to enhance the performance of the radar aided strapdown inertial navigation system (ins/radar). this filter involves the concept of residual-based adaptive estimation and adaptive fading kalman filter and tunes dynamically the fil...

Video satellites have recently become an attractive method of Earth observation, providing consecutive images the Earth’s surface for continuous monitoring specific events. The development on-board optical and communication systems has enabled various applications satellite image sequences. However, video-based target tracking is a challenging research topic in remote sensing due to its relativ...
