Evaluation of new radio occultation observations among small satellites at Venus by data assimilation
Yukiko Fujisawa, Norihiko Sugimoto, Chi Ao +5
We conducted observing system simulation experiments (OSSEs) for radio occultation measurements (RO) among small satellites, which are expected to be useful for future Venus missio…
