Current atmospheric models are incapable of properly modeling all of the density variations in the Earth’s upper atmosphere. Precision orbit ephemerides (POE) are utilized in an orbit determination process to generate improved atmospheric density estimates. Based on their correlation to accelerometer density, the POE density estimates were demonstrated to be an improvement over existing atmospheric models and somewhat better than the improved density estimates from the High Accuracy Satellite Drag Model regardless of solar and geomagnetic activity levels. The POE density estimates were obtained with the desired accuracy for a ±10% variation in the ballistic coefficient used to initialize the process. Fit span length showed little influence ...
