FIELD: physics, measurement. ^ SUBSTANCE: invention concerns navigation device capable of displaying information on movement. Such device is intended for application in onboard navigation system installed at mobile object. Navigation device is programmed with the use of data from map and navigation software allowing for route planning between two user-defined points; during operation device reads information from external memory map where operation system of the device, navigation software and map data are stored. Operation system storage in personal storage device is not required, therefore operation of device requires only insertion of respective memory board. ^ EFFECT: possible application of navigation device without original storage of data (including operation system and navigation software), which means reliable protection of device from breakdown caused by environment, particularly powerful electromagnetic fields. ^ 15 cl, 8 dwg |
