What does Loran mean?
long-range navigation
loran, abbreviation of long-range navigation, land-based system of radio navigation, first developed at the Massachusetts Institute of Technology during World War II for military ships and aircraft located within 600 miles (about 970 km) of the American coast.
What is Loran used for?
LORAN, short for long range navigation, was a hyperbolic radio navigation system developed in the United States during World War II. It was similar to the UK’s Gee system but operated at lower frequencies in order to provide an improved range up to 1,500 miles (2,400 km) with an accuracy of tens of miles.
What is the difference between Loran and Loran-C?
Loran-C is an improved version dating back to the late 1950’s. Loran-C uses a lower frequency, 100 kHz (kHz = kiloHertz = kilocycles/second = thousand cycles per second), compared with 1850 to 1950 kHz for Loran-A. The lower frequency gives Loran-C a longer range and allows for greater accuracy.

What is LORAN and how does it work?
In a hyperbolic system such as LORAN, a receiver on an aircraft or ship picks up radio signals broadcast by one or more pairs of radio stations spaced hundreds of miles apart. The system works by measuring the time delays between signals from the two stations.
How accurate is LORAN?
The absolute accuracy of the Loran-C system varies from approximately 0.1 to 0.25 nautical miles, depending upon the mariners location in the coverage area.
What are the different GNSS?
The four global GNSS systems are – GPS (US), GLONASS (Russia), Galileo (EU), BeiDou (China). Additionally, there are two regional systems – QZSS (Japan) and IRNSS or NavIC (India).
Is Loran C accurate?
The absolute accuracy of LORAN-C varies from 0.10 to 0.25 nmi (185 to 463 m). Repeatable accuracy is much greater, typically from 60 to 300 ft (18 to 91 m).
Is LORAN-C accurate?
What is the advantage of GPS over LORAN-C?
The use of integrated GPS/Loran-C improve GPS availability by only a few percent. In the mountains, the use of an integrated system increases availability to 95% as compared to 65% for GPS and 75% for multi-chain Loran-C.
What N means?
Nitrogen. N. Nano. N. Principal Quantum Number (used in formulae in quantum physics)
