Time Is Relative, Position Absolute

I strode into the plenary session of the ION International Technical Meeting, primed and ready for a barrage of modernity, of out-in-front advances in precision positioning, navigation and timing. The first thing I saw was a 7-foot tall cesium beam tube, an early atomic clock from the 1950s.

Satellite Visibility to Aid Claus Mission

In lead position on a sleigh rising from the North Pole to a height of 200 meters — standard cruising altitude for global package delivery — at 2100 hours UTC on December 24 — the youngest will hopefully be asleep by then and there’s plenty of territory to cover before dawn breaks, time’s a-wasting — navigator Rudolph will see between 40 and 45 GNSS satellites glistening in the night sky.

New Ionospheric Model for Galileo Users

A version of the NeQuick G ionospheric model algorithm to help single-frequency receivers to estimate and correct for the ionospheric propagation delay  is now available for download from the Galileo Service Center (GSC) website). Using a new coding approach, this version is the result of intensive effort by engineers at the EU’s Joint Research Centre.

Live Tests Show Confidence in Driverless Car

An innovative positioning engine based on a safety-oriented paradigm uses a dual-frequency GNSS receiver, automotive cameras, accurate maps, low-cost inertial sensors and vehicle odometry. The real-time integrity layer bounds the error of each estimated value with a confidence level for safe navigation.

Galileo Boarding Trains All Across Europe

This summer, French railway company SNCF performed successful tests of an autonomous train, using Galileo-enabled receivers. The vehicle ran a distance of four kilometers with the help of remote control. SNCF intends to develop its own prototypes of autonomous freight and passenger trains by 2023.

A Very British GNSS Could Be On the Horizon

As the deal/no-deal Brexit conundrum continues to roil UK politics, the British government has quietly sounded out strategic partners in the so-called “Five Eyes” security alliance for help in launching its own satellite positioning system. Due to leave the European Union on October 31, the UK faces a lockout from the continent’s Galileo system and services, most crucially its–as yet unrealized–Public Regulated Service (PRS), an encrypted navigation signal for governmental-authorized users and sensitive applications, that is, the military.

EGNSS, ERTMS Impacting Both Rail and Space

Two years ago, Inside GNSS published a feature article describing some exciting new capabilities and business models making GNSS use a key contributor to deploying European Rail Traffic Management System (ERTMS) on local and regional lines. Today, the train control segment remains one of the most important components of the railway market. In the railway domain, this control segment also is one of the most important in terms of industrial and technological innovation, in particular in Europe with the development and the continuous improvement of the European Rail Traffic Management System/European Train Control System (ERTMS/ETCS) standards.
