The exchange of news bulletins is very popular among amateur packet radio users today. But there are currently no standardized protocols in use, and there is no widespread use of news forwarding protocols at all among amateur TCP/IP stations. This paper discusses how the Network News Transfer Protocol can be used to distribute news between stations on packet radio networks. NNTP is a standardiz...

In software systems development, the increasing size and complexity of systems is handled by decomposition. Companies additionally sign up different subcontractors for subsystems. For distributed development and smooth integration, a major challenge is to deduce subsystem specifications from system specifications in order to deliver them to the subcontractors. Missing information within the sub...

The GEOMÒBIL is a Land Based Mobile Mapping System (LBMMS) developed by the ICC. It is a modular system that allows the direct orientation of any sensor mounted on a roof platform. The GEOMÒBIL system is composed of the following subsystems: orientation subsystem, image subsystem, laser ranging subsystem, synchronization subsystem, power and environmental control subsystem and data extraction s...

We present an approach that allows mission and contingency management to be achieved in a distributed and dynamic manner without any central control over multiple software modules. This approach comprises two key elements—a mission management subsystem and a Canonical Software Architecture (CSA) for a planning subsystem. The mission management subsystem works in conjunction with the planning su...
