Orbit Determination Analysis Utilizing Radiometric and Laser Ranging Measurements for GPS Orbit
| AUTHOR | Administration (Nasa), National Aeronaut |
| PUBLISHER | Independently Published (08/05/2020) |
| PRODUCT TYPE | Paperback (Paperback) |
Description
While navigation systems for the determination of the orbit of the Global Position System (GPS) have proven to be very effective, the current issues involve lowering the error in the GPS satellite ephemerides below their current level. In this document, the results of an orbit determination covariance assessment are provided. The analysis is intended to be the baseline orbit determination study comparing the benefits of adding laser ranging measurements from various numbers of ground stations. Results are shown for two starting longitude assumptions of the satellite location and for nine initial covariance cases for the GPS satellite state vector. Welch, Bryan W. Glenn Research Center NASA/TM-2007-214679, E-15815 WBS 439432.07.04.03.01 GLOBAL POSITIONING SYSTEM; LASER RANGING; ORBIT DETERMINATION; RADIOMETERS; COVARIANCE; EPHEMERIDES; STATE VECTORS; KALMAN FILTERS; LONGITUDE; SPACE NAVIGATION
