Abstract: This paper provides a functional description of a typical Loran-C receiver, with the goal of providing the navigation system specialist with an insight into the processing which is accomplished within the Loran-C receiver. The Loran-C system transmits accurately timed pulses. The receiver’s function is to measure the time, either relative or absolute, at which these pulses arrive at the user’s receiver. To understand how the receiver works, it is necessary fist to understand the signal structure of the Loran-C system. This structure is described to the depth necessary to understand the receiving task and the elements of a typical Loran-C receiver. The receiving task is described in terms of the functional states of: - Initialization - Acquisition - Pulse Group Time Reference Identification - Tracking. Through the description of a typical receiver, the interaction of the various receiver components from the antenna to the display is introduced.
