How does LORAN C work

Because the LORAN-C signal is phase coded, it is usually simpler to sum the obtained signal two GRIs at a time. In other words, the Receiver adds a point in the LORAN-C signal with another point that is exactly two GRIs away. Thus, the Receiver sums several periods of the obtained signal that are phase coded in exactly the same manner Loran-C was a hyperbolic radio navigation system that allowed a receiver to determine its position by listening to low frequency radio signals transmitted by fixed land-based radio beacons.Loran-C combined two different techniques to provide a signal that was both long-range and highly accurate, features that were formerly incompatible

How does Loran C work? LORAN-C signals are transmitted as a series of pulse chains. Generally, a LORAN-C chain (i.e., a specific set of transmitters) propagates anywhere between three and six pulse chains. One of these pulse chains must be a Master, whereas the other pulse chains must be Secondaries. What does Loran-C stand for? [ How LORAN Works. This is a shortened version of the 1947 LORAN for Ocean Navigation filmstrip produced by the Coast Guard as a sales pitch to commercial shipping lines to adopt LORAN (as a both a navigational aid and to assist in distress situations). Updated with a new narration track in place of the distorted period track, the film provides a. Loran-C - Introduction. LORAN-C INTRODUCTION. Loran-C, the successor to Loran-A, was originally developedto provide radionavigation service for U.S. coastal waters and was laterexpanded to include complete coverage of the continental U.S. as well asmost of Alaska. Twenty four U.S. Loran-C stations work in partnership withCanadian and Russian.

A Loran-C receiver computes distances from Loran-C transmitting stations using the time of arrival measurements and the propagation velocity of the radio ground wave to determine position. Small variations in the velocity of propagation between that over sea water and over different land masses are known as the Additional Secondary Factor, or ASF Loran is referred to as a hyperbolic system. In order for the Loran system to work effectively, the Loran receiver must be connecting with at least three transmitting stations. This set of three stations is called a chain. One of these stations is designated as the master station and the other two are secondary stations
