What's the different between active GPS and passive GPS?

Active GPS receives and amplifies the GPS signal it receives from satellites by sending power to the attached GPS antenna.
Active GPS devices will always have a SMA GPS port for an external antenna, which allows for the amplification of the signal.
Active GPS will work better in poor coverage areas. (Areas without direct view of the sky, such as mountainous areas, and urban areas with large buildings).

Passive GPS only receives satellite signal on their internal GPS module. (ie: listening only) It does not amplify the signal.
Passive GPS will require a clear view of the sky; does not work well in poor GPS coverage areas.
Passive GPS devices have Passive GPS annotated in their documentation. (ie: IBR6x0C-150M).
