This is a history of satellite launches in support of the Global Positioning System constellation. Launch dates are UTC.

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

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.
