Trimble R7 and Topcon NET-G3A are two common GPS receivers and both deployed with choke antenna. But two matching antennas are different capacity to suppress multipath effect. The research results that for two types of receivers, the ability of mitigate multipath effect based on P code with low satellite elevation cutoff angle is more effective than C/A code. Comparing with Topcon NET-G3A receiver,...
Concerned with real requirement of software development, this paper point out limitation of the universal computer language courses at the present time. The limitation is the programming language courses pay more attention to the language itself, but ignore other important aspects related to software development. So we introduce the basic skills which should be cultivated through the programming language...
To improve interoperability, resource reusability and agility of complex information systems (CIS), a new integrated development environment (IDE) is proposed. Based on semantic service oriented architecture (SSOA), this new IDE is designed for accommodating requirements involved in development life-cycle of CIS. In addition to providing a framework of the SSOA based IDE, some key enabling technologies...
