Non-dynamic decimeter tracking of earth satellites using the Global Positioning System

摘要: A technique is described for employing the Global Positioning System (GPS) to determine position of a low earth orbiter with decimeter accuracy without need user dynamic models. differential observing strategy used requiring GPS receiver on vehicle and network six ground receivers. The uses continuous record change obtained from carrier phase smooth measurements made pseudo-range. result computationally efficient that can deliver down lowest altitude orbits.
