Abstract
This paper explores the utilization and analysis of a cislunar-based receiver to enhance a network of terrestrial and near-earth space-based passive RF receivers for conducting Space Situational Awareness (SSA) of objects in cislunar space. It models and explores the integration of a cislunar receiver into a network of terrestrial and GEO- based receivers. The added receivers are in various periodic, closed orbits around the Earth-Moon Lagrange points 𝐿 1 , 𝐿 2 , and 𝐿 5 . The addition of the cislunar receiver is beneficial as the estimation accuracy of passive RF systems is based on the geometric orientation of the constituent emitter and receivers and a diverse geometric setup provides greater theoretical accuracy. The orientation’s usefulness for estimation is often measured through the metric of the dilution of precision (DOP). This research effort applies and adapts previous research into UAV-based passive RF estimation where receiver position and velocity uncertainty are considered and adapts/applies it to the problem of augmenting a terrestrial and near-earth passive RF architecture with a cislunar receiver. Provided is a derivation of the relationship between the receivers’ position and velocity uncertainties and relates that to the Cramer -Rao Lower Bound of the anticipated final estimation accuracy of the cislunar emitter.
