Recently, the joint design of the GNSS message structure and the associated channel‐coding
scheme have been investigated as a means to reduce the Time‐To‐First‐Fix (TTFF) and …

In the past, in order for GPS (Global Positioning System) to work accurately, the presence of
an unobstructed LOS (Line-Of- ight) signal was necessary. Weak signals were not suitable …

In this article, we provide the method to construct two error correcting structures for GNSS
systems, which are capable to provide Maximum Distance Separable (MDS), full diversity and …

With the multiplication of navigation systems (GPS, GALILEO, GLONASS, QZSS, ...) the
variety of radio navigation signals to be received increases greatly and involves 8 frequency …

In the current framework of Galileo and thanks to the flexibility of the I/NAV message,
introducing new pages in order to propose an optimization of the E1-B Galileo signal has been …

Geostationary satellites are a very efficient mean to broadcast information to a large number
of users. In the field of navigation they are currently used as Satellite Based Augmentation …

This letter investigates on the derivation of good log likelihood ratio (LLR) approximations
under uncorrelated fading channels with partial statistical channel state information (CSI) at …

New generation of GNSS systems seeks to provide new features in order to create or to improve
their currents services. Between those possible features; the increase of the data rate is …

The design of a new GNSS signal is always a trade-off between improving performance and
increasing complexity, or even between improving different performance criteria. Position …

Reducing the Time To First Fix (TTFF) and improving the resilience of future Galileo signals
are two important characteristics, especially when considering urban environments. To reach …
