08:30 The design and benefits of an SCA based video downlink receiver
Author: Lloyd Palum (Harris Corporation, USA)
Abstract - The use of unmanned systems has increased dramatically over the last 10 years. The original systems integrated commercially available technologies to provide quick fielding of a very valuable tactical and strategic resource. Originally UAS system designers were looking for a relatively simple and easy to deploy set of technologies to build the first viable platforms. Using previous generation analog satellite television transmission and reception technology for video down links allowed the UAS to be rapidly and easily deployed. In the wake of the unmanned platforms fielding success there is now a need to evolve the current systems to take on improved capabilities and security. Software defined radio platforms play a critical part in this evolution. In particular, Harris Corporation is helping to field Software Defined Remote Video Terminals based on the popular Falcon III SCA architecture that provide multi-mode wireless video downlink application support in a single tactical battery operated platform. In this presentation, we will explore the benefits of such an approach and how it can aid in the evolution of ISR video distribution.

08:54 Developing SCA Based Networking Waveform Applications
Author: Ken Dingman (Harris Corp, USA)
Abstract - The Joint Tactical Radio System (JTRS) Software Communications Architecture (SCA) serves as a de-facto international standard defining a set of rules and protocols for military Software Defined Radio (SDR) applications. The European Secure Software Defined Radio (ESSOR) program has adopted the SCA as its base standard for SDR technology, providing diversity and leverage for SCA standards evolution. A key tenant of both the JTRS and ESSOR programs and the use of the SCA is focused on the portability of waveform applications across various radio platforms, thereby facilitating lower cost and shorter time-to-market for the deployment of increased capabilities to war-fighters, in conjunction with improved communications interoperability. This objective is of particularly critical importance for joint force and coalition actions. As the pace on the battlefield accelerates, the need for real-time information is becoming increasingly important hence the demand for development and deployment of IP based networking waveform applications for SCA based radio systems.

09:18 The Benefits of Static Compliance Testing for SCA Next
Authors: James Ezick (Reservoir Labs, USA); Jonathan Springer (Reservoir Labs, USA)
Abstract - The next generation of the Software Communication Architecture (SCA) specification (SCA Next) introduces several features that will affect the compliance certification process. Among the more significant and high-profile changes are the introduction of multiple supported platform models and support for both CORBA and non-CORBA transport layers. These features, which further abstract the specification away from a uniform hardware/software interface, make constructing an all-purpose dynamic testing platform more difficult. This suggests that a certification plan that relies more heavily on static testing might provide a more versatile and cost-effective approach. In this paper we describe the benefits and implications of static compliance testing in the context of SCA Next. This includes a discussion of which requirements are and are not amenable to static testing, the complexity of defining and customizing tests, the expected performance and limitations of those tests, and a summary of our experience derived from the development of R-Check SCA, our platform for static SCA compliance testing.

09:42 Middleware Transports for Embedded Software Radio
Author: Roy Bell (Raytheon, USA)
Abstract - Embedded systems are undeniably migrating from hardware to software, and software systems are undeniably using more standardized software components. Examples include the use of commercial operating systems and middleware products such as web services and CORBA. Some software developers buck the trend by attempting to gain a short-term size or performance advantage using custom software components, but with the increasing speed of processors, increasing size of memory and increasing demand for more functionality; the long-term trend is to use standardized components when they meet the need. This allows developers to reduce time to market or spend their time increasing the functionality and sophistication of their products. The JTRS standard strives to achieve a plug-n-play infrastructure that supports component portability by standardizing the APIs that access and control radio applications and components. These APIs are expressed in both C language and CORBA IDL. Proponents of the CORBA APIs perceive advantages in modularity, reliability, and increased functionality. Proponents of the C language APIs do not extol its virtues, but instead point to perceived CORBA disadvantages in size and performance. We have eliminated these potential disadvantages.
