Abstract(in English) In the system for observing ecology of sea animals, we consider the up-link performance, which is the communication link from the animal station to the observatory satellite. In this system, the most severe issue is the effect of large Doppler shift, which is caused by the rapid movement of very small LEO satellite. In this paper, we discuss a new acquisition scheme finishing synchronization for very short time. This scheme consists of some BPFs with band width considering the symbol frequency. Its performance is shown by analysis and computer simulation. And we show that the new acquisition scheme is appropriating for the observatory system.
