Welcome to the AMMOS Instrument Toolkit (AIT) documentation!

The AMMOS Instrument Toolkit (Formerly the Bespoke Links to Instruments for Surface and Space (BLISS)) is a Python-based software suite developed to handle Ground Data System (GDS), Electronic Ground Support Equipment (EGSE), commanding, telemetry uplink/downlink, and sequencing for JPL International Space Station and CubeSat Missions. It is a generalization and expansion of tools developed for a number of JPL ISS missions.

Visit the Installation and Environment Configuration guide for installation information. Visit the API Documentation page to view in-depth interface documentation.


The AMMOS Instrument Toolkit was formerly known as “BLISS”. You will see references to this, especially in the API Documentation and code snippets, since part of the internal software structure still maintains that provenance.
