Since 2015, China has successfully launched five experimental BeiDou global navigation system (BDS-3) satellites for expanding the regional system to global coverage. An initial performance assessment and characterization analysis of the BDS-3 is presented. Twenty days of tracking data have been collected from eleven monitoring stations. The tracking characteristics and measurement quality are ...

Satellite-tagging is increasingly becoming a powerful biotelemetry approach to obtain remote measurement through tracking free-living cetaceans, which can fill knowledge gaps on cetaceans and facilitate conservation management. Here, we made first biologging attempt baleen whales in Chinese waters. An adult Bryde’s whale the Beibu Gulf was tagged investigate potential occurrence areas migration...

Target tracking and missile tracking radars and the radar test set on a block. Function of the acquisition radar system and the TTR and target ranging radar.in location-aware systems and services. In this paper we present RADAR, a radio-frequency RF based system for locating and tracking users inside buildings.dent laboratory model of the radar system that can be used for monopulse tracking. Ur...

In this paper, we show how an Earth watching mission, dedicated to the detection and the tracking of forest fires and volcanic eruptions, and involving a constellation of low-orbiting satellites, equipped with detection and observation instruments, can be reactively and efficiently managed via the cooperation of decision modules implemented on the ground in a mission control center and onboard ...

This paper presents a new approach to evaluating performance of real-time component based software by introducing a new measure called software sensitivity. The measure is based on the evaluation of relative changes in the number of missed deadlines when their lengths are being decreased. Experimental results were obtained for the satellite ground control station’s tracking component developed ...

multiple people detection and tracking is a challenging task in real-world crowded scenes. in this paper, we have presented an online multiple people tracking-by-detection approach with a single camera. we have detected objects with deformable part models and a visual background extractor. in the tracking phase we have used a combination of support vector machine (svm) person-specific classifie...
