Report: Russian Navy Gets New Precision Terrestrial System to Backup GPS/GLONASS

According to a news report,“Sprut-N1 [a] new-generation precision navigation radio system (RNS) has been created for the Russian Navy. It will determine geographic location, speed and altitude with a precision superior to that of GLONASS and GPS. The coordinates are determined by ground stations of the system which transmit coded signals to warships and aircraft. The main advantage against satellite navigation is that the signal of the high-tech system cannot be jammed, the Izvestia daily writes.”

Government Researchers Working to Address GPS Vulnerabilities

Two recent reports have underscored the threats to the GPS system from space-capable adversaries. Both the Worldwide Threat Assessment, released Jan. 30 by the Senate Select Committee on Intelligence, and theDefense Intelligence Agency’s newly released Challenges to Security in Spacedetail the potential for China, Russia and others to damage the constellation or disrupt its signals.

With worries mounting about these risks, and the more mundane but still harmful prospect of regional jamming or spoofing, organizations throughout the U.S. government are working on ways to address vulnerabilities and find ways to operate without GPS.

Working Papers: Speed Verification in the Smart Tachograph

The Smart Tachograph (ST), the new revision of the Digital Tachograph (DT), aims to improve safety in the transportation sector by monitoring the behavior of commercial drivers. For this purpose, data from several sensors, including a GNSS receiver, are recorded, processed and cross-validated. In this article, the motion conflict procedure adopted by the ST is reviewed and experimentally evaluated using data collected in light urban and highway environments.

International Committee on GNSS-13 Focuses on PNT in High Earth Orbit and Beyond

Since last reported in the November/December 2016 issue of Inside GNSS, significant progress has been made to extend the use of Global Navigation Satellite Systems (GNSS) for Positioning, Navigation, and Timing (PNT) in High Earth Orbit (HEO). This update describes the results of international efforts that are enabling mission planners to confidently employ GNSS signals in HEO and how researchers are extending the use of GNSS out to lunar distances.

Scalable, Traceable Time for Datacenters Using GNSS and White Rabbit

Accurate and reliable timing and synchronization can be an enabler of diverse new applications in datacenters. Accurate clocks across different nodes make possible key functions like consistency, event ordering, causality and the scheduling of tasks and resources with precise timing. In this article the authors take a close look at scalable and traceable time for datacenters using GNSS and White Rabbit.

Geolocation Data Could Get Privacy Protection Under New ADD Act

New legislation aiming to protect the privacy of internet and phone users could shield not just their browsing and buying habits but their location information as well.

The American Data Dissemination (ADD) Act, introduced by Sen. Marco Rubio on January 16, covers service providers that use the internet and “collect records” — a very broad definition. The Act will also be enforced against common carriers — that is telecommunications companies.
