This paper considers the formation tracking control problem of concomitant satellites by using STK (Satellite Tool Kit). A new sliding mode control protocol which is suitable to fight against the gravitational perturbation is proposed to achieve the robust tracking around the given orbit. Information flows are able to be translated in STK simulations by using the time-share scheme. The effective of...
This paper aims at revealing how land use and land cover change in a subtropical coastal watershed of Southeast China, which has enormous influence on the region's economic and ecological health. Land sat Thematic Map per satellite imagery of 1986, 1996 and 2007 were used to create maps of each time point for 6 land categories. The results show that Built increased while Agriculture shrunk from 1986...
Impervious surface areas (ISA) play an important role in determining the water quality of the receiving waters. Remote Sensing, Geographical Information System, and multiple regression techniques were coupled in this study to detect the impervious surface area dynamics over the last 20 years and the linkage between ISA and Chemical permanganate index (CODMn), Ammonia (NH4+-N), and total phosphorus...
This paper measures land-use transition in three time intervals in a typical county with high-level agriculture intensification, Southeast China. Landsat Thematic Mapper satellite imagery of 1986, 1996, 2002 and 2007 is used to create maps of each time point for the categories: Agriculture, Natural and Built. The results show that the rate of change has accelerated from 1986 to 2007 for Agriculture,...
