INTEGRATED INERTIAL SATELLITE SYSTEM FOR ORIENTATION AND NAVIGATION Russian patent published in 2012 - IPC G01C21/00 

FIELD: instrument making.

SUBSTANCE: integrated orientation and navigation system (IONS) includes gimballess inertial measuring module (GIMM) with measuring unit on "rough" gyros and accelerometers, as well as miniature receiving equipment of satellite navigation system (SNS RA) with phase measurements and equally spaced antennae in generation of object orientation parameters. Formation of differential measurements (between GIMM and SNS RA) is performed on the level of primary parameters (design and measured values of the second differences of signal phases at carrying frequency, which are received at points of arrangement on the object of SNS RA receiving antennae), and their processing is performed individually for each pair of observed navigation satellites; arrangement of GIMM measuring unit and reference antenna of SNS RA is performed at maximum possible distance from mass centre of the object (it is expedient to perform their arrangement at one point of the object).

EFFECT: higher accuracy and interference immunity.
