Abstract
Cislunar space is expected to see a large increase in number of users over the next few decades.
As a result, a cislunar positioning, navigation, and timing (PNT) service should be implemented in
order to meet the demanding needs of users. Focus is placed on a near term version of the system
that will cater to areas of interest in cislunar space, namely the lunar south pole. A standard set
of metrics, including coverage and Positional Dilution of Precision (PDOP), are utilized to assess
and compare various system configurations proposed in literature. Architectural changes are
imposed onto literature constellations to produce novel constellations with the goal of increasing
performance, which is achieved. To systematically improve constellation performance, an
optimization process to determine the optimal satellite positioning along defined orbits is used
to minimize PNT estimate errors. Optimized constellations are developed and compared to the
originals in which it is seen that major performance increases are possible.
