A ground-based optical telescope equipped with CCD sensor has become an important tool for space debris monitoring in order to maintain a space debris catalogues. In this paper, we emphasized on an enhanced technique for a small and dimming space object extraction. Traditionally, the static background subtraction based on median image technique is widely used to extract the moving space object in...
An indoor positioning system based on Receive Signal Strength Indication(RSSI) from wireless access equipment has become very popular in recent years. This system is very useful in many applications such as tracking service for older people or customer inside living communities, mobile robot localization, logistics systems etc. While outdoor environment using Global Navigation Satellite System(GNSS)...
Indoor positioning system based on Receive Signal Strength Indication(RSSI) from Wireless access equipment have become very popular in recent years. This system is very useful in many applications such as tracking service for older people, mobile robot localization and so on. While Outdoor environment using Global Navigation Satellite System(GNSS) and cellular[14] network works well and widespread...
In autonomous navigation systems, localization is the most important problem to be solved. In this note, we propose the algorithm to localize an unmanned ground vehicle (UGV) equipped with a global positioning system (GPS), an odometer and an electronic compass. The proposed scheme is based on the unscented Kalman filter (UKF). To improve the accuracy and robustness, the novel noise model of data...
