Talk
Six COSMIC-2 spacecraft were launched into low Earth orbit in June, 2019 aboard a SpaceX Falcon Heavy rocket. The primary instrument on all six spacecraft is the TriG Radio-occultation System (TGRS). TGRS is to provide operational weather data for both ionosphere and neutral atmosphere via radio occultation. TGRS features GPS and GLONASS signal processing and a digital beam forming phased-array antenna to greatly increase SNR. Radio occultation SNR is expected to be ~3x higher than COSMIC-1. This presentation will provide general TGRS status and early evaluation of the instrument and some of the performance statistics versus the objectives for the mission.
