Developed in-house at NASA GSFC
SLR2000 is designed to be a completely autonomous Satellite
Laser Ranging (SLR) system. The software must not only interface
to the hardware and collect ranging data, but it must also
make all of the decisions concerning what to track, when to
track, and when there are problems that require help. The six
SLR2000 computer subsystems that perform these functions are:
- Interface and Control Computer (ICC) - DOS on Pentium II,
interfaces to mount, ranging electronics, and star camera
- Dome Control System (DCS) - DOS (microchip controllers),
controls the dome position and shutter
- Pseudo-OPerator (POP) - LynxOS on Pentium (embedded VME),
automates operator function
- Data ANalysis
computer (DAN) - LynxOS on Pentium (embedded
VME), provides post processing, non - realtime hardware interface,
and web site
- Health AND Safety (HandS) - Windows NT on Pentium II (Compact
PCI), monitors system health and interfaces to security system
- Remote Access
Terminal (RAT) - Linux (currently Pentium
II laptop), provides interface to SLR2000 for humans (direct
or remote)
