Proceedings of the 31st International Technical Meeting of The Satellite Division of the Institute of Navigation (ION GNSS+ 2018).
This work presents a channel model validation campaign performed by the authors comparing field tests against laboratory tests using a hardware simulator and the ITU recommendation P.681-8 channel model as simulation tool. Two different live tests we

2014 7th ESA Workshop on Satellite Navigation Technologies and European Workshop on GNSS Signals and Signal Processing (NAVITEC).
The most recent generation of Global Navigation Satellite Systems (GNSS) are implementing Binary Offset Carrier (BOC) modulation. The advantage of BOC signals is that the main lobe of the correlation is very narrow, but on the other hand, they presen

The usage of BOC modulations in GNSS provides a better code tracking accuracy than BPSK modulation at the cost of new correlation peaks appearing in the autocorrelation function. For high-order BOC modulations side peaks might be only few meters away
