Responsibilities:Principal software engineer and analyst for C-MIGITS INS/GPS system. The C-MIGITS system is based on Systron Donner’s digital quartz inertial measurement unit (IMU) technology. It uses a 28-state Kalman filter to integrate inertial measurements with global positioning satellite (GPS) data. Work involved real-time embedded software.(TI C31 DSP processors) and test support/data reduction software. Developed covariance analysis simulation tool based on the C-MIGITS Kalman filter and generated system requirements for a DO-178B IMU. Past duties included developing a web-based database application that inventories and documents all software assets and artifacts (thousands of legacy C/C++ modules and test-related job control scripts and test data files, compilers, debuggers, etc.). The purpose of this effort was to foster an understanding of the legacy software architecture and components associated with this line of business and provide a database-driven support framework for software maintenance. The application uses J2EE technologies, specifically, JDBC, JSP, Servlets, and JavaBeans. Using Forte for Java as the IDE and SQL server on Win32 platforms. The middleware for this project consists of the Apache-Jakarta Project's Tomcat Servlet Engine, using Jakarta ant (Java-based make utility) and the Jakarta DBTags Tag Library. The legacy test support system will be migrated over the next year to a Java-based, platform-independent, distributed system. |
