In this presentation, we will investigate four time series models for estimating the population of Earth-orbiting satellites. Since 1957's launch of Sputnik 1, space access has grown steadily more accessible as more nations and private actors have access to launch capability. Today, even a small team of high school students can assemble and launch a space satellite on a reasonable budget.
Servicing the orbiting hardware population includes launch, tracking, and communications. Understanding the demand for space access is necessary for establishing the business case for providing service, as well as future tracking of space debris and other on-orbit risks.
Using publicly available data from the Joint Force Space Component Commander's Space-Track system, we construct four time series models for estimating the on-orbit population of four different orbit classifications. These models are used to predict populations for ten year periods, going forward.
