Shared Reconnaissance Pod (SHARP)

V_Systems developed the software for an advanced reconnaissance system to be used with the Navy F/A 18 - E/F and P-3 aircraft. The software developed was written in C/C++ and included subsystem management functions, inertial navigation functions, Aircraft to Pod interface management, Back-Seat display interface. Integrated into the system is a fully functional TAMPS system. One of the most advance features of the system is the "auto-mode" which utilizes, artificial intelligence, INS data, and application of complex physical calculations in the form of an expert system to allow for proper sensor pointing to maximize useable data for each mission. Manual mode allows for nominal mission exercise, as well as point and look capability based on unscheduled imaging opportunities. Data is recorded in real-time on SSR and Tape devices and can be downlinked in real-time or post pass via CDL to appropriate ground equipment.

Dragon Warrior

V_Systems developed the software for an advanced reconnaissance system to be used on an Unmanned Aerial Vehicle (UAV). The software developed was written in C/C++ and included subsystem management functions and inertial navigation functions. The UAV is used to gather high-resolution data and imagery for use by marine expeditionary units.

Interim Control Module (ICM) for the International Space Station

The Command and Control System is comprised of a Sun Ultra SPARC running Solaris 2.6. V_Systems developed the Solaris Device Drivers for custom and COTS hardware to provide real-time access to spacecraft data as well as simulated data. The Hardware interfaces were implemented with custom and COTS VME hardware modules in 6U and 3U formats. The interface to the SPARC from the VMEbus was via an sBus to VMEbus adapter. This adapter as well as the real-time requirement for the data manipulation necessitated the implementation of the driver level software.

The command and control application consisted of X-Windows based software to display data in both textual and graphical formats, including data trending charts. The GUI also facilitated single spacecraft commands as well as batch or automated commanding in sequence. The telemetry application is a Solaris based decommutation algorithm based on an Oracle Database. The telemetry decomm is part of the COMET system. This is also an X-Windows based application.

The simulator provided real-time response to commands that were routed to the simulator rather than the actual spacecraft. The simulator was implemented with the VxWorks real-time operating system for the real-time components and Windows NT applications for the GUI. V_Systems played an integral role in the development of the Solaris, VxWorks, and NT applications, and we also provided testing and validation support required for NASA Safety Standards. The application was for a manned mission.

The Launch Support Equipment was a subset of the command and control system. It utilized custom electronics to mate with the Shuttle Umbilical and the Payload Interrogator to monitor payload health prior to launch.

The command and control system was expanded into three models, one dedicated to spacecraft integration and test, one dedicated to mission software development and test, and one dedicated to mission simulation for training of NASA personnel located remotely at Johnson Space Center.

DSP MGT DU Replacement

V_Systems provided software and hardware upgrades to legacy data collection and processing equipment AN-UYS-1A. V_Systems ported the device drivers from the legacy system to a COTS ruggedized Power PC based system. Additionally, V_Systems provided the systems analysis for input to stabilize unreliable hardware chassis design for improvement to meet mission requirements.

Optical Network Infrastructure

V_Systems developed two board support packages (BSP) for custom hardware. The hardware incorporated the use of both a Motorola MPC 8260 Power PC Processor and a PM/PPC 750 Power PC Processor. In addition to this task, we developed and implemented of a non-VxWorks shell and test software for these boards. The test software allows the production line to exercise all contained hardware before the board is shipped without the requirement of VxWorks.
