| 摘要 |
<p>A method and apparatus are disclosed for processing and transmitting precise orbit predictions of satellites in a Global Navigation Satellite System such as Navstar-GPS or a communication device such as Iridium which employs force models and curve fitting techniques to encode ephemerides, and particularly ephemerides of duration of a month, in order to minimize bandwidth requirements over-the-air and NVRAM storage requirements. The methods also apply to GNSS constellations such as Galileo or GLONASS.</p> |
