Relativistic Effects on SV Clocks Due to Orbit Changes, and Due to Earth's Oblateness

Abstract

Improvements in GPS motivate attention to some small relativistic effects which have long been known, but have previously been too small to be explicitly considered. For SV clocks, these include frequency changes due to orbit adjustments, and effects due to the earth's oblateness. For example between 25 July and 10 October 2000, SV43 occupied a transfer orbit while it was moved from slot F5 to slot F3.
