1. An Automatic Dependent Surveillance-Broadcast (ADS-B) device to be carried by an aircraft comprising:
an ADS-B controller and an ADS-B radio frequency (RF) transmitter coupled thereto and configured to
determine aircraft actual flight position data comprising aircraft actual altitude data and aircraft actual surface position data,
generate aircraft coarse accuracy flight position data based upon the aircraft actual flight position data,
generate aircraft fine accuracy flight position data based upon the aircraft actual flight position data, the aircraft fine accuracy flight position data having a greater accuracy than the aircraft coarse accuracy flight position data,
transmit aircraft flight identification data, and
transmit aircraft flight position data comprising the aircraft coarse accuracy flight position data and the aircraft fine accuracy flight position data.
