FIELD: instrumentation.
SUBSTANCE: invention relates to instrument making and is used in strapdown inertial navigation systems (SINS). Essence of the claimed invention consists in the fact that in the device for determining the angles of roll, pitch and true heading, comprising a base module with a set of metallized contact pads, on which there is a microcontroller, which includes a quartz resonator, there is also a unit of accelerators and angular velocity sensors, a magnetometer. Each contact pad is made in the form of a half-hole, the axis of which is located perpendicular to the surface of the base module, and the quartz resonator is installed inside the microcontroller.
EFFECT: reduced power consumption, simplified technology of printed circuit board production.
