Global Navigation Satellite Systems Engineering, Policy, and Design
Crowdsourcing has gained some attention in the GNSS community as a means for detecting and mitigating RF interference and signal spoofing.
In the past year, researchers and commercial ventures have developed ways to take advantage of the GNSS-derived knowledge of real-time location of participants to create ad hoc networks of couriers.

Lawmakers are poised to sharply limit the ability of foreign nations to own or control satellite system monitoring stations on U.S. territory, a rare show of congressional cooperation triggered by a Russian request to place stations supporting its satellite navigation system on American soil.

√ The USA will stop printing nautical charts next April, the end of a 150 year tradition. Why? “Declining demand, electronic and digital charts and federal budget realities,” said NOAA’s Office of Coast Survey. They will maintain and update PDFs of more than a thousand coastal charts and refer those who admire traditional lithography to private printers who can do the job.
Highway safety officials are crafting guidelines aimed at pushing manufacturers to make portable electronic devices — including cell phones, hand-held navigation receivers, and navigation apps — less likely to distract drivers. They may face some push back, however, from members of Congress who are already questioning whether GNSS devices should be included under the proposed standards.

With the R&S SMBV-K107 option the GNSS simulator now covers the BeiDou standard as well as those for GPS, Galileo, and GLONASS.

Jules McNeff, Overlook SystemsTechnologies, Inc.EDITOR’S NOTE: Jules McNeff answers additional questions on the subject of spectrum protection and sharing in a special “GNSS Forum” extension of this installment of the "Thought Leadership Series" in this issue of Inside GNSS.
As Mark Twain once famously told a petitioner for investment advice: “Buy land. They are not making it any more.”
So it is with radio frequency spectrum, a limited and finite resource.

GPS/BeiDou/MEMS configuration and GPS/MEMS configuration (left and right, respectively, top photo), Front view (center photo) and back view (lower photo) of nAX5.2Due to the huge success of GPS in both military and civil applications, several other GNSSs have been developed, built, and operated in the last few decades. GNSS, regional, and augmentation systems are comprise a growing family that also includes GLONASS, Galileo, BeiDou, and Japan’s Quasi-Zenith Satellite System (QZSS). New members, such as the Global Indian Navigation System (GINS), are preparing to join in next decade.

Prompted by reports of a sharp deterioration in the quantity and quality of 911-caller automatic location information, the Federal Communications Commission (FCC) is weighing new requirements for phone companies to help emergency personnel find cell phone users in need of aid.
Data from emergency providers show that a rapidly declining number of 911 calls from mobile phone users come in without the accurate location information needed to find the person calling for help.
