Yesterday we completed our first quarterly technical review with the Navy SPAWAR on the development of our Land-Mobile SATCOM Network Simulator (LMSNS).  The review went very well, and the Navy was impressed with the progress we have made on the software design and development.  They were especially impressed with the degree of flexibility that our performance simulator will provide while at the same time allowing users to build up models over time, adding complexity as they uncover more details of the system they are trying to simulate.  This is important to them as many of the performance modeling tools they have require complete inputs to run.  These complete inputs can mean hundreds or thousands of entries into the simulator.  This is fine when you know them, but often you do not, and users want a simulator that can run with partial or simple inputs.  Further, simple models can provide insight into the effects of various changes that complex models may hide.  Such features and capabilities seemed to find a favorable ear with the Navy.  Next quarter, we continue to build our simulator.  We are rapidly closing on the design, and coding will begin in earnest in a week or so.  If you have interests or stories regarding satellite or wireless performance simulations, we would love to hear from you.  Please post any comments and stories.

On September 17, 2009 we were awarded a Phase II SBIR contract for the development of a prototype of our Land-mobile Satellite Network Simulator. We kicked off the contract in early October and have been working on the software design. We are employing UML to define the structure and create a generic design that can be easilly carried into other software environments. We have been so busy or blogging has taken a back seat, but I hope the New Year will bring a reinvoration of my blogging.

On January 10th, Questiny received notification from SPAWAR that they would exercise the option on our Phase I SBIR on Land-mobile Satellite Communications: Improved Mathematical Methods for Stressed Users. In addition, on January 25, 2009 we submitted our Phase II proposal to SPAWAR for consideration. Together, the Phase I Option and the Phase II effort will prototype an advanced discrete event satellite communications simulator for US military UHF satellite communications. This simulator employs our advances in land-mobile satellite channel models, and our advanced design in discrete-event radio propagation modeling. When completed, this tool will provide a comprehensive US military communications planning tool.
