Influence of Attitude Errors on Angle-of-Arrival Receivers in Satellite Systems

The context is satellite systems with an antenna array payload. The satellite has to geolocate an emitter of electromagnetic waves placed on the surface of the Earth. The sensing technique is angle of arrival (AOA). The objective of the paper is to model, simulate, and quantify the influence of errors in the attitude d...

Distance Measurement by a Galileo GNSS Receiver Using the Signal E6-C

The new concept of air traffic control favours the global navigation satellite system (GNSS) Galileo over the classic navigation system. Practice shows that GNSSs are unreliable when operating in the presence of interference. That is why we examined the feasibility of measuring the distance between a Galileo receiver o...
