5Low-Cost Our Specialty
- No software licensing cost
- Portable - fully functional on all supported
platforms - PC (FreeBSD, Linux, or Solaris)
- Workstation
- Laptop
- Distributed - can utilize several inexpensive
computers for higher performance - Provides infrastructure required for lights-out
operations. - Easily interfaces to add-on products such as
Altair, Apprentice, Genie, and LabView. - Database driven - ITOS software need not be
customized from mission to mission - No custom front-end required
6Adaptability
- Migrates from development labs to operations
- Board/box level
- Subsystem level
- Integration and test
- Mission operations
- Easy interfaces have made ITOS an ideal test bed
for integration of new technology - LabView, Matlab, PV-Wave, VirtualSat, Apprentice,
SOTG - SERS, Genie/GenSAA, SMEX DPS, DTAS
- Supports science instrument development and
operations - Provides data to existing instrument support
equipment - Serves as a base for developing new instrument
support equipment - Handles many data formats including CCSDS and TDM
- Laptop configuration will be used by shuttle
astronauts to check-out Spartan free-flyers prior
to deployment
7Innovations
- Extreme low cost
- Makes extensive use of freely available software,
operating systems, and technical support - Scalable - supports everything from board-level
testing to operations - WWW interface for remote monitoring
- Traditional spacecraft front-end processing
performed in software
8Innovations
- Makes use of Java programming language for
portability, WWW remote monitoring and telemetry
displays - Provides simple interfaces for integrating new
technology or custom software. - ITOS supports autonomy by providing in its
scripting language - Socket, file, and device I/O (including control
of IEEE-488 devices) - Access to the operating system
- Compatible with wide variety of ground stations
and networks - DSN, USN, TOTS, LEO-T, TSI, STDN, TDRSS, AFSCN,
Inmarsat
