NAS Implementation - Procedures - RNAV (GPS)
Area Navigation (RNAV) a method of navigation that permits aircraft operation on any desired flight path within the coverage of ground or space based navigation aids or within the limits of the capability of self-contained aids, or a combination of these. (AIM, section 1-2-1)
Reliance on RNAV systems for instrument operations is becoming more commonplace with the use of systems such as GPS and augmented GPS, such as WAAS and GBAS. (For more information, see the AIM, section 5-4-5)

These lines of minimum include:
More information can be found in the RNAV (GPS) Approaches fact sheet (PDF).
