Integrated Test and Operations System (ITOS)

ITOS is a comprehensive command and telemetry solution for spacecraft, component, and instrument development, integration, test, and mission operations. It is highly user configurable, and provides a scalable, cost-effective platform for small-budget projects to billion-dollar observatories. Includes multi-spacecraft control and closed-loop simulation capabilities.

ITOS Description - See Technical Approach display

ITOS software need not be customized from mission to mission. Implements highly-evolved language for describing telemetry and command layout and processing.
All customers share a single release; no mission-specific, dead-end versions are created
Comprehensive product includes advanced telemetry and command processing; broad I/O capabilities including TCP/IP, SLE, CFDP, and GMSEC*; web-based displays.
Automation provided by STOL* interpreter, configuration monitor, and schedule executor (for time-based automation) to support lights-out operations.
No license costs for end-users.
* SLE: Space Link Extension; CFDP:CCSDS File Delivery Protocol;
GMSEC: Goddard Mission Services Evolution Center; STOL: System Test & Operations Language

Scalable from board-level testing to on-orbit operations.
Designed for control of multiple spacecraft from a single console.
Includes capabilities for closed-loop simulation of spacecraft, instruments, or other components.
Traditional spacecraft front-end processing performed in software.

Can be applied to any application involving real-time monitoring, control, and data distribution.
Very low cost and highly user-configurable.
Advanced, modular design for quick, low-cost customizations when needed.
