Lockheed Martin, Space
§ Performing Reliability Analysis on various spacecraft projects including:
o Worst Case Analysis on Power Supply for a GOES-R Lightning Mapper Instrument
o Fuse Analysis for the SBIRS power subsystem
§ Consulting on the TIROS weather satellite program. Services rendered including:
o Test Software development (ATLAS software),
o Digital Box troubleshoot,
o Overstress analysis,
o Specification work including Test Verification matrices
o Test Equipment design
§ Design of an upgraded flight computer test equipment:
o Troubleshoot of a test rack of equipment that was in storage for 10 years.
o Removal of the Tecmar Computer (8086 based, S-100 Bus with CP/M operating system)
o Integration of a Pentium III ruggedized personal computer running Windows XP operating system
o Upgrade from CPM Pascal software to Microsoft Visual Studio 6.0 C with plug and play digital I/O cards
o Mechanical modifications of all the hardware.
o Conversion of all Test Procedures to use the new equipment
§ Test and troubleshoot Flight Computer for spacecraft
o Identified the cause of a previous unverified failure on a spacecraft computer that had failed in test on the ground.
§ Design of an upgraded reaction wheel assembly (RWA) test equipment:
o Remove an HP-85 from the system and replace with Pentium IV computer as control computer.
o Modify the original Program in HP BASIC with code in HT BASIC.
o Integrate A/D converter and IEEE 488 bus card with GPIB output in PC
o Design an X-Y plotter replacement for voltages -10 to +10V as the X-Axis and -10V to +10V as the Y-Axis using an A/D Converter card and Pentium IV computer.
§ Development of an Electrical Test Procedure (ETP) to test Special Test Equipment:
o In order to ensure that automated or manual test equipment is safe to mate to a flight component, a test program is run. This routine guarantees that the STE is safe to mate to the flight component. In addition, this operation will help eliminate pesky Unverified Failures (UVFs) that can crop up when the test equipment is not operating at its designed capacity.
§ Test and troubleshoot of the TIROS Spacecraft simulator at the Spacecraft Operations and Control Center (SOCC)
o Troubleshoot electronic board failures that prevented communication with Wallops Is. Site.
§ Rebuild of ancient Wire Wrap electronics boards:
o FXO Inc was able to capture the design of an electronics board and rebuild two spare boards from the design. There were obstacles to overcome here. The main problem was finding obsolete components and the equipment to program PAL and EPLD devices.
§ Service Contract on Spacecraft Simulator:
o FXO Inc performs periodic maintenance and repair as needed of two spacecraft simulators. We have in the past successfully troubleshot and repaired various failures.
§ Fuse Analysis on Spacecraft Power System:
o FXO Inc completed the analysis of the fusing circuits on a Lockheed Martin designed spacecraft.
