Code Shift Keying

The constant growth and evolution of the positioning, navigation, and timing (PNT) market generate demands for more and more added-value applications and services relying on GNSS signals, with expectations for improved accuracy and availability. Some services may also rely on added-value content other than navigation messages, for example, higher data volume with less latency, such as the data carried by satellite-based augmentation system (SBAS) services and the Galileo Commercial Service.

How Important Is It to Synchronize the Code and Phase Measurements of a GNSS Receiver?

Q: How Important Is It to Synchronize the Code and Phase Measurements of a GNSS Receiver?

A: Precise timing lies at the heart of GNSS implementation and operation and is generally well understood in terms of synchronizing individual satellites and/or receivers. Recent results, however, have demonstrated that timing of code and phase measurements in a receiver can have significant implications for the timing community in particular.

Stuart Riley: Right Turn from the Wrong Path

Stuart Riley’s Compass Points

Stuart Riley was born and raised in Nottingham, England, where some of the crucial crossroads in his career appeared quite early.

One such inflection point came when he was just 10 or 11, and it involved a birthday present from his sister, Alison.

eCall

On April 28, 2015, the European Parliament voted in favor of an eCall regulation, which requires all new models of passenger cars and light vans that will be certified for the European market to be equipped with the automated emergency-call technology beginning in April 2018. The measure applies to all such vehicles regardless of selling price. In the future, a similar service may be implemented for trucks as well.

State of Play in the European Union

Global navigation satellite systems have become core elements of the global economy. Essential for many civilian applications and innovations, GNSS brings rapidly growing economic benefits due to convergence of GNSS with smartphones, geospatial data, unmanned aerial vehicles, automated driving systems and other commercial technologies.
