Lockheed Martin, Space Systems Company
§ 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.
