Columbia, MD (February 5, 2002) Dot21 Real-Time Systems, a leading provider of real-time publish/subscribe middleware for the military and embedded applications, announced today the availability of its products and services through the Government Services Administration (GSA) Schedule under contract #GS-35F-0197M. This qualification now makes Dot21 services easily available to all federal, state and local government agencies including the Army, Navy, Air Force, Department of Defense, and NASA.

Dot21 helps application developers reduce product development cycles by providing tools that enable embedded systems programmers to bypass lower level programming tasks. With less time spent on basic programming, developers can focus on strategic application development -- that means shorter development schedules, faster product delivery, and ultimately greater satisfaction for the end-user.

Dot21’s middleware is an enhanced version of the message-oriented middleware currently used in Navy programs such as Cooperative Engagement Capability (CEC), SPS-48E Auxiliary Detection Processor (ADP), and Ship Self-Defense (SSDS). Dot21’s message-oriented middleware reduces time to market for systems utilizing inter-processor communications by providing a solution that works across various interconnect technologies such as Ethernet, VMEbus, etc. and which can easily be ported to new platforms. Dot21’s middleware reduces software development costs by employing a publish-subscribe paradigm that decouples distributed applications thereby simplifying system design. Time synchronization between platforms is yet another unique feature that the middleware provides which is often a critical requirement for complex real-time systems.

Dot21’s suite of analysis tools work in conjunction with the middleware to further reduce the effort associated with integrating large, complex systems. Data recorded during system operation can easily be filtered (based on numerous graphically specified criteria), plotted, formatted for display, and replayed to give the developer insight into system operation. For Radar applications, a special "PowerTool" is available to allow visual filtering of data using a PPI type display. Dot21’s customers don’t spend valuable time developing custom software to analyze their data!

Dot21 also provides complete solutions to its customers including real-time system design and analysis, software design, Java™display technology, device drivers, and embedded board support packages. "Our engineers have an average of 15 years experience in the software industry," says John Strong, Dot21’s Director of Engineering. "Whether our customer needs a device driver or a Java™ display, we have what it takes to get the job done", says Strong.

About Dot 21 Real-Time Systems Dot21 Real-Time Systems, Inc. (Dot21) specializes in software for real-time and embedded systems. Dot21 was launched in May 1999 as a spin-off of the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, MD, to commercialize the message-oriented middleware used in several Navy programs including Cooperative Engagement Capability (CEC), Ship Self-Defense (SSDS), and the SPS-48 ADP. Dot21 is located in the Howard County Neotech Incubator in Columbia, MD, midway between Baltimore and Washington D.C.
