Interesting project I had the pleasure of being involved in.

Mind's Eye Observatory was one of the two Dual latitude sites.

This paper investigates utilizing dual-latitude optical measurements for improved orbit and attitude estimation of spacecraft. High-cadence optical measurements(i.e. images) are processed to reduce noise and maximize detection of Resident Space Objects (RSOs). A method of autonomously identifying RSOs in continuous imagery provides angular measurements to an Extended Kalman Filter to perform orbit estimation.

Data gathered on a Geostationary satellite.
