{{Use dmy dates|date=May 2013}}{{As of|December 2018}}, 73 Global Positioning System navigation satellites have been launched, 31 of which are operational, 9 in reserve, 1 being tested, 30 have been retired and 2 were lost at launch. The constellation requires a minimum of 24 operational satellites, and the official target count is 33.[1]

SVNs are "space vehicle numbers" which are serial numbers assigned to each GPS satellite. PRNs are the "pseudo-random noise" sequences, or Gold codes, that each satellite transmits to differentiate itself from other satellites in the active constellation.

Once launched, GPS satellites do not change their plane assignment but slot assignments are somewhat arbitrary and are subject to change.

Cross reference of PRNs to satellite blocks

The following table is for the purpose of making it possible to determine the block associated with a PRN by looking at one column in one table rather than having to search through all rows of three tables. Thus this table can be used to quickly and easily determine the number of satellites in orbit and health associated with each block.

PRN to SVN history

This section is for the purpose of making it possible to determine the PRN associated with a SVN at a particular epoch. For example, SVN 049 had been assigned PRNs 01, 24, 27, and 30 at different times of its lifespan, whereas PRN 01 had been assigned to SVNs 032, 037, 049, 035, and 063 at different epochs. This information can be found in the IGS [https://web.archive.org/web/20131013225217/http://igscb.jpl.nasa.gov/igscb/station/general/antex14.txt ANTEX] file, which uses the convention "GNN" and "GNNN" for PRNs and SVNs, respectively. For example, SVN 049 is described as:
