## Low-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**

## Adaptability

**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**

## Innovations
