Goddard Enhanced Onboard Navigation System (GEONS) V3.0

About this technology

Overview

The National Aeronautics and Space Administration (NASA) Goddard Space Flight Center (GSFC) has developed the capability to provide high-accuracy orbit and time autonomously onboard NASA spacecraft. The GSFC Mission Engineering and Systems Analysis Division has implemented NASA-developed navigation algorithms for high-accuracy real-time onboard orbit determination in the Goddard Enhanced Onboard Navigation System (GEONS) flight software. The GEONS flight software is flight proven, currently providing onboard orbit determination (OD) for the Global Precipitation Mission (GPM) and the Magnetospheric Multiscale Mission (MMS). GEONS processes many measurement types to estimate the orbital states of one of or more satellites using an extended Kalman filter orbit determination algorithm.
