FIELD: navigation system.
SUBSTANCE: invention relates to satellite navigation. Object of the present invention is piloting device (1) with sensors for rotary-wing aircraft (2), comprising at least two IMU inertial modules (51, 52), at least two GNSS reception means (11, 12, 13, 14), equipped respectively with a first module for detecting and eliminating malfunctions FDE1 (21, 22) and covering different GNSS (100, 200, 300, 400), at least two second fault detection and elimination modules FDE2 (31), at least two hybridization platforms (61, 62) and at least one third fault detection and elimination module FDE3 (41). FDE1, FDE2, FDE3 detection and elimination modules (21, 22, 31, 41) allow detection of reliable and/or false signals, to exclude every faulty GNSS system (100, 200, 300, 400). Besides, each hybridization platform (61, 62) makes it possible to determine hybrid speed relative to the ground, in order to finally give the accurate and reliable speed of said aircraft (2).
EFFECT: technical result is the detection of reliable and/or false signals to exclude every faulty GNSS navigation satellite system (100, 200, 300, 400).
