==== Relativistic corrections ====
The GPS implements two major corrections to its time signals for relativistic effects: one for relative velocity of satellite and receiver, using the special theory of relativity, and one for the difference in gravitational potential between satellite and receiver, using general relativity. The acceleration of the satellite could also be computed independently as a correction, depending on purpose, but normally the effect is already dealt with in the first two corrections.<ref>{{Citation|last1=Fliegel|first1=Henry F.|last2=DiEsposti|first2=Raymond S.|date=December 1996|publisher=The Aerospace Corporation|location=El Segundo, CA|title=GPS and relativity overview|url=https://apps.dtic.mil/dtic/tr/fulltext/u2/a516975.pdf|access-date=December 7, 2022|archive-date=March 6, 2023|archive-url=https://web.archive.org/web/20230306071351/https://apps.dtic.mil/dtic/tr/fulltext/u2/a516975.pdf|url-status=dead}}</ref><ref>{{Cite journal |last=Ashby |first=Neil |date=2003 |title=Relativity in the Global Positioning System |journal=Living Reviews in Relativity |volume=6 |issue=1 |pages=1 |doi=10.12942/lrr-2003-1 |doi-access=free |issn=1433-8351 |pmc=5253894 |pmid=28163638|bibcode=2003LRR.....6....1A }}</ref>
