The Probe for Radio Occultation oF Ionospheric LayErs (PROFILE) is a GNSS radio occultation receiver designed to operate on NASA’s upcoming Geospace Dynamics Constellation (GDC) mission. PROFILE will make remote sensing measurements of the electron density profiles and combined with 5 in-situ sensors the measurements will provide critical information on space weather effects in the upper atmosphere. GDC will include six satellites to be launched into a near polar orbit, and during ~2 years of time the satellites will be spread gradually, allowing for the first time to comprehensively observe the global response across multiple temporal and spatial scales. For this study, we estimate the numbers of radio occultations that could be obtained by PROFILE during various phases of the mission. We also evaluate how the remote sensing observations would leverage with the in-situ measurements to maximize the science return from GDC.
