FIELD: physics.
SUBSTANCE: air-navigation device with inertia sensors and radio-navigation receivers with three measurement channels is characterised by that in two (10, 12) of the three channels, inertial measurement units belong to the MEMS type with "low characteristics" with gyrometres of the class from approximately 1°/h to 10°/h, and the third channel has an inertial measurement unit (15), whose characteristics conform to the ARINC 738 standard.
EFFECT: longer average time between two failures and ensuring lowest cost while maintaining the required course accuracy.
