Development of a command and control system for the operation of Space Vehicles.Developed a Java application to capture streaming telemetry data, perform decommutation of the data and save the data to a Big Data store to be used for subsequent query and analysis. This application uses Cloudera Software’s distribution of Apache Hadoop and their stack of services for processing and storage of the telemetry data. These services include HDFS, Yarn, Kafka, HBase and Spark. Development in C# of a process responsible for managing the state variables available and configurable within the system. The process queries a PostgreSQL database for the static system values and Redis, an in-memory database cache, for the dynamic system values.

Development of a system to manage the operation of Space Vehicles. This included development in Java of a JEE application that processes ephemeris data received from these vehicles. Calculations are performed on this data to determine when vehicles are in view of ground antennas, and other information that may affect the operation of the vehicle. This data is then persisted to an Oracle database.Developed in C# web services to query the database for data used for planning and scheduling of these vehicles.
