Najvažniji i po dimenziji najveći deo inercijalnog navigacijskog sistema (INS) predstavlja inercijalni merni blok (IMB). U članku se analizira pouzdanost pet mogućih arhitektura IMB sa stanovišta pouzdanosti pojedinih komponenti (senzora-žiroskopa i akcelerometara, procesora, unutrasnje i spoljašnje magistrate podataka, bloka za napajanje, generatora taktnih impulsa i programabilnih brojača), njihovom pojedinačnom doprinosu smanjenju pouzdanosti IMB i primene redundanse tih komponenti radi povećanja pouzdanosti IMB. / The most important and utmost per dimension unit of the inertial navigation sistem (INS) is the inertial measurement unit (IMU). This paper analyzes reliabilitu of five possible IMU architectures from the point of view of particular system components reliability (sensor-gyro and accelerometer processor, internal and external data bus, power supply, clock function and programmable counters), their individual contribution to of reliability decreasing IMU and implementation redundancy of this system components in order to increase IMU reliability.
