JUNO navigation for Jupiter orbit insertion

Juno arrived at Jupiter on 05 July 2016 UTC, achieving orbit with the execution
of the Jupiter Orbit Insertion (JOI) maneuver. Thanks to a dynamically wellbehaved
spacecraft, the delivery of Juno to JOI was done largely with only a
maneuver to setup and Earth gravity assist (EGA), an EGA, an EGA clean-up
maneuver, and a JOI targeting maneuver. During the last several weeks of the
approach to JOI, the dominant uncertainties in the predicted trajectory were
from the Jupiter barycenter ephemeris. In this paper, we discuss the maneuver
and orbit determination (OD) strategy for successfully arriving at JOI, the the
challenges of calculating a correction to the Jupiter barycenter ephemeris using
only radiometric data types, and how the ephemeris estimates during approach
to JOI compare to a post-JOI trajectory reconstruction.
