COMPASS Location and Service System is one of the important ways to improve the COMPASS service level and achieve social and economic benefit. With the characteristic of COMPASS RDSS Communication, COMPASS Location & Service System can be widely-distributed and has more layers. To build this system to be meet with the Requirements, we use the Component-based software development method(CBSD) technique. This paper designed a CBSD-based Application Architecture which include General Framework, Functional Modules, Component Composition for COMPASS Location and Service System, and provided an true Project Application at last.
