Ctek’s Dual-Mode GPS application is a general purpose GPS application that can be installed on any Ctek SkyRouter. When installed the application is administered from SkyRouter’s Application environment using a web browser. The Dual-Mode GPS application operates with the internal GPS capabilities of the M and Z Series models 4200 and 4400 as well as an external GPS unit on all SkyRouters.
The Dual-Mode GPS application takes its name from its ability to simultaneously update a AVL server application and a client application such as Microsoft’s Streets and Trips or DeLorme. Figure 1 of the document shows the architecture of a Z4200 using the full set of capabilities available in the Dual-Mode GPS application.
