Our Next DC/Baltimore ACM SIGAda Chapter Meeting
is scheduled for
Tuesday, 9 May 2006 at 7:30 P.M. (Light Refreshments at 7:00 PM)
Kevin Richardson, of The MITRE Corporation
will be speaking on
The Software Communications Architecture (SCA)
and the Building of Software Defined Radios
at the MITRE 2 Building in McLean, Virginia
Light Refreshments will be served starting at 7:00 PM. The presentation starts promptly at 7:30 PM. You are encouraged to network after the meeting.
Foreign Nationals should please register for the meeting by COB Friday, 5 May 2006, by leaving a message for Mr. Currie Colket at (703) 983-7381 or firstname.lastname@example.org. Please include your full name, your company affiliation, citizenship, and phone number.
The intent of this briefing is to provide an overview of the Joint Tactical Radio System (JTRS) Software Communications Architecture (SCA) used to build software defined radios. The talk will address how providers of software defined radios would use the specification to engineer/develop the radios. In addition the talk will address standardization activities that have been influenced by the SCA such as the Platform Independent Model (PIM) and Platform Specific Model (PSM) for Software Radio Components Specification which is in the process of standardization within the Object Management Group (OMG). These specifications strive to establish (to certain degrees) a platform and language neutral architectural framework upon which Software Defined Radios can be constructed. Lastly, the talk will provide a high level overview of the evolutionary strategy for the SCA.
Kevin Richardson is a Software Systems Engineer who has been with The MITRE Corporation since 2000. Throughout his MITRE career he has been involved with the Joint Tactical Radio System (JTRS) program and the development of the Software Communications Architecture (SCA). His SCA tasks have included working with JTRS product developers who are attempting to leverage the SCA framework, supporting the development of SCA compliance test tools and providing consulting services to the JTRS Test and Evaluation organization in order to adjudicate requirement interpretation discrepancies. In parallel with performing those tasks he served for two years as the chairperson of the JTRS Technical Architecture Group (TAG), the organization that provided final recommendations on the changes to be incorporated within the SCA. He has worked extensively with standards/specification organizations within the Software Defined Radio domain, the most prominent being the Object Management Group (OMG) and the Software Defined Radio Forum. His recent focus has been to assisting in the evolution of the SCA as a supporting member of the JTRS Joint Program Executive Organization (JPEO).

At the DC/Baltimore SIGAda meeting on 22 August 2005 held joint with the DC ACM Chapter, we viewed the webcast of the ACM Turing Award Lecture. Vinton G. Cerf and Robert E. Kahn, Recipients of the ACM 2004 Turing Award spoke on Assessing the Internet: Lessons Learned, Strategies for Evolution, and Future Possibilities. The lecture was webcast from ACM SIGCOMM 2005 in Philadelphia, Pennsylvania. ACM has archived the webcast at http://www.acm.org/sigs/sigcomm/sigcomm2005/webcast.html for your viewing pleasure.
Bill Bail gave an excellent presentation on Requirements Engineering for Dependable Systems on 11 October 2005. Slides from his presentation are available online as
