This research features an overview of the available PLB technologies, their advantages, shortcomings and areas of their optimum application. A test of the locator transmitter emitting both 406 MHz AIS and 121.5 MHz signals was performed with a focus on tracking the homing 121.5 MHz signal. The efficiency of the homing signal was examined by using two separate radio locating systems. One of them comprised multi-purpose and widely available components and programs, while the other was a specialised radio beacon system with dedicated components. In addition to the results, their analysis and evaluation of efficiency, the paper discusses the applicability of the available PLB technologies and provides guidelines for adequate selection of the PLB devices and position indicating radio equipment.
