Software products
Our software Shell packages are components for developing telecommand and telemetry systems supporting CCSDS, ESA and ECSS standards and recommendations. They have been used in many operational space applications.
The Shells are all highly portable and can be used on any system with an ANSI-standard C compiler. They are off-the-shelf software components for building
- spacecraft ground control systems
- on-board spacecraft control systems
- spacecraft ground testing systems (EGSE)
- simulators and demonstrations.
Telecommand products
Two Shells support spacecraft telecommand, including the TC Space Data Link Protocol, the Communications Operation Procedure-1 (COP-1) and the channel coding (BCH code):In earlier CCSDS and ESA standards, the TC Space Data Link Protocol was called Packet Telecommand.
Telecommand security products and options
We have products for telecommand security and authentication:- Segment Level Security Interface (SLSI) for external implementation of security features
- Telecommand Authentication with ESA Authentication Unit (AU)
The following products support security:
- SLSI option with the Telecommand Encoder Shell and Telecommand Decoder Shell
- ESA AU option with the Telecommand Encoder Shell and Telecommand Decoder Shell
- free-standing Authentication Unit Shell package
Telemetry products
Two Shells support spacecraft telemetry, including the TM Space Data Link Protocol:In earlier CCSDS and ESA standards, the TM Space Data Link Protocol was called Packet Telemetry.
AOS telemetry/telecommand products
Two Shells support Advanced Orbiting Systems (AOS) telemetry and telecommand, including the AOS Space Data Link Protocol:Simulator
Our telecommand and telemetry simulator is a tool for demonstrating a spacecraft communications system based on the telecommand and telemetry standards:
