regulations.gov - Department of Transportation seeks comments on plans to implement eLoran
"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 tosupport 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 co"

Opening Up Indoors: Japan’s Indoor Messaging System, IMES : GPS World 2011
"An indoor messaging system (IMES) has been developed to meet the challenges of indoor and deep indoor positioning, as a system that can be implemented in any device that has a GPS/GNSS receiver without hardware modification. IMES can provide reliable 3D position data with a single transmitter device without performing range calculation."

Indoor Location Highlighted at Famous Vehicle Research Center | GPS World July 2013
Via Jim Litton "The Insurance Institute for Highway Safety (IIHS) has contracted Locata to provide local, ground-based precision positioning signals for vehicle testing in a new $30-million expansion at the famous Vehicle Research Center, focused on vehicle automation testing. A novel indoor section of the expansion will allow replication of parking garages and urban canyons — where GPS will be largely masked — and will enable evaluation of technologies such as forward collision-avoidance systems in adverse conditions." "LocataNet, which will provide the VRC with high-precision positioning to enable rigorous, consistent and repeatable scientific evaluation of new vehicle crash avoidance systems." "ocata’s autonomous positioning technology uses terrestrial networks that function as a “local ground-based replica” of GPS-style positioning. Locata works with GPS, but can also operate independently when GPS is not robust or is completely unavailable."
