| 1. A receiver for determining geolocation, comprising:
a Global Positioning System (GPS) receiver section, wherein the GPS receiver section is selectively switchable between a standalone
mode and at least one other mode for determining a geolocation of the receiver, wherein the at least one other mode is selected
from a group consisting of an autonomous mode, an augmented autonomous mode, a network aided mode, a network centric mode,
a network based mode, and a reverse aiding mode, and wherein the selective switching occurs substantially simultaneously with
the determination of the geolocation of the receiver.
