LORAN or “long range navigation” is a proven positioning and navigation system initially developed during World War II to provide long range and highly accurate navigation for aircraft and maritime applications.
LORAN utilizes high power, low frequency radio signals transmitted from land based radio towers to provide full PNT services
LORAN technology was the most common and widely used navigation system in North America, Europe, Japan and the entire Atlantic and Pacific areas and it currently managed and operated by the US Coast Guard
Comprised of 19 radio stations that serve the 48 continental states, their coastal areas and parts of Alaska
Enhanced LORAN or eLORAN is a next generation LORAN technology and is the most suitable backup to GPS.
3 million times stronger than GPS
High power/low bandwidth signal is highly resilient to jamming, spoofing or interference
Can penetrate through buildings, underground and underwater
Low cost alternative source of PNT
Highly scalable for widespread adoption
Terrestrial system versus space based
Wireless, Stratum 1 independent source of timing
POSITIONING:Combined with mapping and other location tools, positioning provides a user their current 2 or 3 dimensional location relative to other objects.
This information is the foundation of all location based services such as navigation, asset tracking, distance and route determination and total proximity situational awareness
NAVIGATION:Navigation allows a user to take the location information described above and apply corrections to course, orientation and speed to navigate to a desired destination.
Navigation is a critical capability for many industries
Most surface (land and sea) and airborne navigation systems (GPS navigation is mandated by the FAA for commercial aviation by 2020) are critically dependent on GPS
TIMING: In addition to positioning and navigation, GPS is the sole source for frequency, phase and precision time synchronization critical for today’s data and telecommunication network services.
GPS provides precise time and frequency information from standardized time sources (Coordinated Universal Time)
Critical timing is measured to the billionths of a second (nanoseconds)
Includes time stamp synching, time oscillation in networks and frequency synchronization
As a society, we are intimately connected to and reliant on GPS.
Transportation systems, military and intelligence operations, financial institutions, communications networks, utility infrastructures and countless other systems are directly dependent on GPS signals from space
Disruptions to GPS pose a legitimate national security threat to the United States and have significant commercial and financial impacts on the national economy and critical infrastructure sectors.
GPS is a single point of failure for PNT services and is easily disrupted by jamming, spoofing, weather events and other sources of interference
Currently there is no independent, sustainable and cost effective backup to GPS
Approximately $1.5 of the $16 trillion dollar US economy is directly linked to the uninterrupted availability of GPS for PNT.
There are currently 5 billion users of GPS, 1 billion in the United States
Of the 16 critical infrastructures / Key Resource Sectors in the US, 15 use GPS for timing… 13 would not function without it
