DEPARTMENT OF TRANSPORTATION


Complementary Positioning, Navigation, and Timing Capability; 
Notice; Request for Public Comments

AGENCY: Office of the Assistant Secretary for Research and Technology, 
Department of Transportation.

ACTION: Notice; request for public comments.

-----------------------------------------------------------------------

SUMMARY: The purpose of this notice is to seek comment from the public 
and industry regarding potential plans by the United States Government 
to implement an enhanced Long Range Navigation (eLoran) system as a 
complementary positioning, navigation, and timing (PNT) capability to 
the Global Positioning System (GPS). The positioning, navigation, and 
timing performance of eLoran will vary widely depending on the number 
of transmitters and monitor sites for corrections that are implemented.
    The Department of Transportation seeks input on: (a) A brief 
description of your application(s) of positioning, navigation, and 
timing services; (b) the positioning, navigation, and/or timing 
performance required for a complementary PNT capability to

[[Page 15269]]

support operations during a disruption of GPS that could last for 
longer than a day, (c) availability and coverage area required for a 
complementary PNT capability, (d) willingness to equip with an eLoran 
receiver to reduce or prevent operational and/or economic consequences 
from a GPS disruption, (e) current and planned availability of e-Loran 
capable user equipment, (f) other non-eLoran PNT technologies or 
operational procedures, currently available or planned, that could be 
used during a disruption of GPS for longer than a day.

SUPPLEMENTARY INFORMATION:

Background and Purpose

    The United States Space-Based Positioning, Navigation, and Timing 
policy requires that the Department of Transportation in coordination 
with the Department of Homeland Security, develop, acquire, operate, 
and maintain backup positioning, navigation, and timing capabilities 
that can support critical transportation, homeland security, and other 
critical civil and commercial infrastructure applications within the 
United States, in the event of a disruption of the Global Positioning 
System or other space-based positioning, navigation, and timing 
services. The United States Government is currently investigating 
implementation of an eLoran system to serve as a complementary PNT 
capability to GPS. The positioning, navigation, and timing performance 
of eLoran will vary widely depending on the number of transmitters and 
monitor sites for corrections that are implemented.
    The Department of Transportation seeks input on: (a) A brief 
description of your application(s) of positioning, navigation, and 
timing services; (b) the positioning, navigation, and/or timing 
performance required for a complementary PNT capability during a 
disruption of GPS that could last for longer than a day, (c) 
availability and coverage area required for a complementary PNT 
capability, (d) willingness to equip with an eLoran receiver to reduce 
or prevent operational and/or economic consequences from a GPS 
disruption, (e) current and planned availability of e-Loran capable 
user equipment,(f) other non-eLoran PNT technologies or operational 
procedures, currently available or planned, that could be used during a 
disruption of GPS for longer than a day.
