Radio systems for long‐range navigation comprise a subclass of radio‐navigation systems based on geodetically referenced and synchronized chains of terrestrial transmitting stations that provide accurate navigation at distances far from those stations. In fact, their development was an attempt to solve the problem of how to minimize the number of terrestrial transmitting stations needed to encompass the global operational area. The chapter aims at representing the very low frequency (VLF) and low frequency (LF) long‐range navigation systems including their principles of operation, accuracy, coverage, budget of errors, interfering signals, signal processing techniques, and sensor architecture. These subjects are augmented by including various system modernization aspects and their integration with satellite RNS. The Integrated Solution utilizes both GNSS and all‐Loran data to estimate additional secondary factor (ASF) corrections. The chapter provides all Loran‐only and GNSS‐only solutions to show how the GNSS or all Loran data contributes to the combined solutions.
