Use case ESA ExoMars TGO Electra Use XTCE in shadow mode for Electra between JPL and ESA ESA requested Electra CMD and TLM dictionaries in XTCE format Results of the conversion of the ExoMars Trace Gas Orbiter (TGO) Electra Command and Telemetry Dictionary to the XTCE standard will be shown. We have used our tool to read the telemetry description provided in Word and Excel files and performed conversion into XTCE files. We studied in detailed the heartbeat key telemetry message and performed validation using mission data.

JPL collaboration with ESA Rosetta MIRO Instrument MIRO is the first microwave instrument sent into space to study a solar system body. As a combined spectrometer and radiometer, MIRO can sense temperature and identify chemicals. Rosetta scientists will use it to determine how different materials in the comet change from ice to gas, and to observe how much comet C-G changes in temperature as it approaches the sun.
