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

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

We currently provide support for two types of telecommand security:

Security options:

Addition of Space Data Link Security (SDLS) for Telecommand

The September 2015 issue of the TC Space Data Link Protocol standard (CCSDS 232.0-B-3) includes the specification of the interfaces between the TC protocol and the Space Data Link Security Protocol (SDLS). We are currently updating the Telecommand Encoder Shell and Telecommand Decoder Shell to include optional interfaces to the SDLS protocol.

Telemetry and AOS 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.

Two Shells support Advanced Orbiting Systems (AOS) telemetry and telecommand, including the AOS Space Data Link Protocol:

Addition of SDLS security for Telemetry and AOS

The September 2015 issues of the TM Space Data Link Protocol standard (CCSDS 132.0-B-2) and the AOS Space Data Link Protocol standard (CCSDS 732.0-B-3) include the specification of the interfaces of the TM and AOS protocols to the Space Data Link Security Protocol (SDLS). We are currently updating the Telemetry and AOS Shells to include optional interfaces to the SDLS protocol.
