Orbit Determination Demonstration Using Onboard One-Way Radiometrics from the Iris Radio on the CAPSTONE Mission

Onboard one-way radiometric tracking from an Iris radio paired with a Chip Scale Atomic Clock (CSAC) on NASA’s CAPSTONE mission has been col-lected and demonstrated to be able to determine its near rectilinear halo orbit. This is a first-ever demonstration of one-way radiometric tracking originating from the DSN and being collected onboard a spacecraft. For CAPSTONE, the tracking data from the Iris/CSAC pair are shown to have sufficient accuracy to enable future autonomous radio navigation for missions with modest navigation requirements. This work will compare the space-based data with prior ground-based test results, as well as assess CAPSTONE’s orbit solution accuracy from the one-way data and compare it to ground two-way tracking solutions.
