Before we launch space weather "sentinels" that take measurements upstream of L1 for advanced warning, we need to determine the optimal orbit for such platforms and investigate how space weather forecasting tools need to be modified for sub-L1 measurements. Multiple classes of orbits are possible, which can take the sentinels more or less upstream of Earth and away from the Sun-Earth line. The growth of rideshare opportunities, the availability of low-cost smallsat platforms, and the maturation of “standardized” space instrumentation make it possible to design and develop a smallsat platform for large-scale interplanetary studies (SPLIS), a smallsat with propulsion and the typical suite of in-situ measurements that fits within an ESPA-size and constraints or smaller. Such a platform can be launched as a rideshare on a variety of orbits in the near-Earth interplanetary space. Combined with assets at L1, it can be used to study the variation of properties of IP structures in the near-Earth interplanetary environment, complementing remote observations provided by missions at Earth (SOHO, PUNCH, SWFO-L1) and future L5 mission. This model could then be applied to develop a constellation of sub-L1 in-situ sentinels with orbits constrained by the physical knowledge gained from this initial constellation.
