NGS Continues Lead Role in International Effort to Pinpoint Position of Satellites

For a second four-year term beginning on Jan. 1, National Geodetic Survey (NGS) is leading an international effort to produce extremely accurate orbits for all satellites in the Global Positioning System (GPS). This vital endeavor ensures worldwide users can achieve accurate positions when processing GPS data. As the Analysis Center Coordinator, NGS coordinates the work of nine analysis centers within the international partnership responsible for high-precision orbits and other products. High-precision GPS satellite orbit determination is an essential requirement for GPS users to access the NGS-managed National Spatial Reference System and obtain positions at the centimeter level or better.
