Abstract: The present invention relates to a device (16) for determining the attitude of a carrier comprising a GNSS receiver apt to receive GNSS signals from one or a plurality of antennas (14) arranged in known positions;



the determination device (16) comprising:

a movement generation module (22) configured for generating a movement of an apparent phase center according to a control law;
a control module (23) configured for determining the control law;
a determination module (24) configured for determining an absolute orientation of a vector of interest from at least one observable value supplied by the GNSS receiver (12) and from the control law, and for determining at least one component of the attitude of the carrier from the absolute orientation of the vector of interest.

Abstract: An electronic portion of a CRPA antenna of an anti-jamming device for a GNSS receiver, including M elementary signal inputs, for each input, a bandpass filter bank which is configured to break down each elementary signal received by this input at a frequency Fe, into P sub-bands to obtain P sub-sampled signals at a frequency Fe/P, a calculational component which is configured to apply in parallel anti-jamming processing at the frequency Fe/P to the sub-sampled signals, to obtain a cleaned sub-sampled signal, and a summation component which is configured to receive all the cleaned sub-sampled signals and to form, from these sub-sampled signals a resulting corresponding cleaned signal at the frequency Fe.

Abstract: A GNSS signal multipath detection device (16) for a GNSS receiver (12) on-board a carrier further comprising one or a plurality of antennas (14) and comprising:



a movement generation module (22) configured for generating a movement of an apparent phase center according to a control law;
a control module (23) configured for determining the control law;
a prediction module (24) configured for determining a prediction of an observable value provided by the GNSS receiver (12), from the control law and directions of arrival of the GNSS signals;
an anomaly detection module (25) configured for detecting multipaths by comparing an observable value coming from the GNSS receiver (12) with the corresponding prediction thereof.
