Conference Paper
Full-text available
Orbit Determination is a technique used to estimate the position of a satellite from its observable measurements. Missing or incorrect modeling of troposphere and ionosphere delays is one of the major error source in space geodetic techniques such as Global Navigation Satellite Systems (GNSS). Accurate computation of these two delays is a mandatory...
Conference Paper
Full-text available
Space agencies generally use numerical methods to meet their orbit determination needs. Due to the ever increasing number of space objects, the development of new orbit determination methods becomes essential. DSST is an orbit propagator based on a semi-analytical theory. It combines the accuracy of numerical propagation and the speed of analytical...
Conference Paper

Earth orbital space suffers from the ever increasing count of space objects, including operational satellites and space debris. Space system operations rely on the management of vast catalogs of objects to avoid any damaging collision. NORAD (North American Aerospace Defense Command) and NASA (National Aeronautics and Space Administration) both mai...
Conference Paper
Full-text available
The paper presents an open-source orbit determination application based on the Draper Semi-analytical Satellite Theory (DSST) and a recursive filter, the Extended Semi-analytical Kalman Filter (ESKF). The ESKF reconciles the conflicting goal of the DSST perturbation theory (i.e., large step size) and the Extended Kalman Filter (EKF) theory (i.e., r...
Conference Paper
Full-text available
Space objects catalog maintenance demands an accurate and fast Orbit Determination (OD) process to cope with the ever increasing number of observed space objects. The development of new methods, that answer the two previous problems, becomes essential. Presented as an alternative to numerical and analytical methods, the Draper Semi-analytical Sat...

Question
Hi, I use two models to calculate the atmosphere density during a satellite orbit propagation. The two models are NRLMSISE-00 and DTM-2000. To feed the models I'm using Space Weather Data provided by Celestrak (https://celestrak.com/SpaceData/SW-Last5Years.txt). I was surprised the see that both adjusted and observed data are provided in this file. I found that observed data must be used for NRLMSISE-00 model. However, I didn't see any information about which type of data to use (i.e., adjusted or observed) for DTM-2000. Does anyone have the answer or a reference?
