Explicit (Noniterative) Loran Solution
Navigation, 1967the main computational requirement for LORAN navigation systems is the transformation to geographic latitude and longitude of time difference measurements made by the LORAN receiver. It is desirable to maintain a computational accuracy of less than one second of arc to avoid degradation of the inherently attainable LORAN system accuracy.

Most of you are familiar with standard Loran (Loran-A) which has been in operation and providing radio-navigation service for nearly two decades. Briefly, Loran-A consists of transmissions of accurately timed, carefully shaped pulses of radio-frequency energy from synchronized master-slave stations to a user in the service area. The navigator's Loran-A

Time synchronization from Loran-C
IEEE Spectrum, 1968Loran-C navigational transmissions, at a frequency of 100 kHz, can be used to provide clock synchronization over long distances to accuracies within ±1 ?s. Results to date represent improvements as great as three magnitudes over other operational long-range radio systems.

Curves for Loran-Inertial Analysis
Navigation, 1967Curves are presented which permit an approximate but rapid error analysis of Loran equipment either when working alone or when aided by an Inertial Reference or an Attitude/Heading Reference. These curves also permit identification of the desirable values of the major parameters of Loran and Inertial equipment when they are working together.
