Preliminary Design of a Model to Assess the Effect of Space Surveillance Network(SSN) Sensor Upgrades on Orbit Prediction Accuracies Relative to the U.S. Anti-Satellite (ASAT) Mission

摘要

This study gives a basis for implementation of a model to assess the effect ofproposed sensor upgrades to the Space Surveillance Network (SSN) to determine if more accurate orbital element set predictions by the Space Surveillance Center (SSC) can be obtained for U.S. anti-satellite (ASAT) targeting. Handoff orbital element set predictions to nearby ASAT facilities for single, low-orbit satellite passes over a single radar sensor are considered. Model development began with simulation of the selected satellites passing over the selected sensors producing baseline truth observations based on the NORAD Simplified General Publications (SGP4) model. Sensor errors, in the form of biases and standard deviations were then factored into the model to produce representative sensor observations from the baseline truth observations. A detailed statistical analysis was performed, utilizing experimental design techniques, to allow for follow-on model development to input the representative observations into a differential correction process to produce predicted orbits.
