High resolution CARTOSAT-1 satellite with its along track stereo capability has opened a number of applications. With fore and aft images looking at +26° and -5° respectively, the satellite is lookin...
Automatic image measuring is to identify and to measure conjugate points in two or more overlapping photographs automatically. In digital photogrammetry, this process is done by image matching. A str...
The GPS precise surveying which is prevailing in Korea now grasps the problem that the result of the GPS observed value is used without the analysis of the relationship between the geometric strengt...
People’s Republic of China is one of the most rapidly developing countries in the world today. There is a great demand on highly actual and accurate spatial information of the whole country, especia...
Today, differential GPS techniques allow common GPS receivers to achieve the precision levels required for mapping purposes. The development of systems for mobile Internet access (mainly GPRS) provide...
The necessity to get positioning in the most precise way and in the briefest time assumes great importance either in the navigational field or in the geodetic surveys. The GPS system is really the mos...
The DGPS/IMU can measure position and velocity extremely high, and it is widely used in air-borne InSAR system. The passage based on the DGPS/IMU's action in the airborne InSAR system, makes sure the ...
鉴于遗传算法(GA)所具有的全局搜索特性,也为了更快速准确地解算差分全球定位系统(DGPS)整周模糊度,将自适应遗传算法(AGA)引入DGPS整周模糊度的搜索中。首先根据全球定位系统(GPS)载波相位双差方程求解出双差整周模糊度的浮点解,并以基线长度作为约束条件确定整周模糊度的搜索范围;然后利用白化滤波的方法对整周模糊度进行降相关处理,降低整周模糊度各分量之间的相关性;最后将自适应遗传算法应用在整...
