FP7 ATMOP

ATMOP (Advanced Thermosphere Modeling for Orbit Prediction).

ATMOP (Advanced Thermosphere Modeling for Orbit Prediction) was a European collaborative project aiming at improving the prediction of satellite orbits. The project brought together 6 teams from 2011 to 2013 and was coordinated by DEIMOS (Spain).

Orbit prediction is an important issue for space agencies and relies on models that provide real-time density of the Earth’s upper atmosphere. One of the main inputs of such models is the solar UV flux. The role of the LPC2E was to deliver improved nowcasts and forecasts of this flux.

ATMOP’s main achievement is an improvement in orbit forecasting, notably thanks to the update of the DTM orbitography model, and the use of a new proxy for solar activity, the radio flux at a wavelength of 30 cm.

These improvements are currently being pursued as part of a collaboration between CNES, the Collecte Location Satellites (CLS) company and the LPC2E, as well as through a participation in a Space Situational Awareness (SSA) project of the European Space Agency.
