register a first navigation time from the navigation unit,

send a request to the RFID reader for acquiring the unique identifier,

receive the unique identifier from the RFID reader,

register a second navigation time from the navigation unit,

calculate the round-trip air time by subtracting the first navigation time from the second navigation time, and

provide, to the message reporting processor, the second navigation time, the received unique identifier, and the calculated round-trip air time; and

the message reporting processor is further configured to generate a base station reporting message for output via the second antenna.

7. The position tracking system of claim 6, wherein the base station reporting message comprises:

a current system time;

an identification of a corresponding on of the at least one movable base station;

a current location of the corresponding on of the at least one movable base station;

the received unique identifier; and

the calculated round-trip air time.

8. The position tracking system of claim 3, wherein:

the base station message database comprises at least one data record for each message received from the at least one moveable base station via the command post transceiver;

each of the at least one data records comprises;

a time a message was reported;

an identification of a corresponding one of the at least one moveable base station;

a location of a the one of the at least one moveable base station;

the unique electronic identifier; and

a round-trip air time.

9. The position tracking system of claim 3, wherein the responder data record associated with the responder location database comprises:
