The Cospas-Sarsat MEOSAR (Medium-Altitude Earth Orbit Search and Rescue) system has been in the news quite a bit of late, and with good reason. As the technology has evolved, so too has the ability to improve search and rescue operations which save lives.
The cover story for the current issue of Inside GNSS is dedicated to the Cospas-Sarsat MEOSAR system and its role as a solution to support the ICAO GADSS Autonomous Distress Tracking recommendation.

Hopping in the car and firing up the navigation system, only to have it take you in precisely the wrong direction while it gets its bearings, will be a thing of the past for South Korean users of combined GPS/eLoran navigation systems when the nation’s new eLoran network comes on line in 2020.

Just more than 60 years ago the U.S Naval Research Laboratory (NRL) launched what has become the longest remaining man-made object in space.
Launched in March 1958, Vanguard I, a component of the Vanguard Project, is a small aluminum sphere (16.5 centimeters in diameter) that was designed to partake in the International Geophysical Year (IGY) — a series of coordinated observations of various geophysical phenomena during solar maximum, spanning July 1957 through December 1958.

Who knows what’s in store for this year’s 15th edition of the European Satellite Navigation Competition (ESNC), which is currently scouting for new business ideas through July 31, 2018. The innovation competition annually awards the best services, products, and business ideas using satellite navigation in everyday life.

The issue at hand is whether the Federal Communications Commission (FCC) should allow a change in the use of frequencies close to those used by GPS. Virginia-based Ligado Networks wants to repurpose its satellite frequencies to also support ground-based telecom services. Testing done several years ago and expanded upon more recently has shown such a system could seriously interfere with GPS receivers.
Some three months after a meeting of the key federal agencies using and running the GPS program, they have yet to release a letter stating their recommendation on whether to allow the development of a potentially interfering telecommunication service.

Online voting for the Institute of Navigation’s Satellite Division Officers will be available after July 16, and ION is currently accepting additional nominations.
The Satellite Division Nominating Committee, chaired by Dr. John Betz, has submitted the following nominations for Satellite Division Officers:
Chair: Dr. Chris Hegarty, The MITRE Corporation; Vice Chair: Ms. Patricia Doherty, Boston College; Ms. Sandy Kennedy, Hexagon Positioning Intelligence/NovAtel, Canada; Secretary: Dr. Zak Kassas, The University of California, Riverside; Dr. Jason Rife, Tufts University; Treasurer: Mr. Tim Murphy, Boeing; and Dr. Alex Stratton, Rockwell Collins.
Pursuant to Article IV of The Institute of Navigation Satellite Division Bylaws, “Additional nominations may be made by petition signed by at least 25 members entitled to vote for the office for which the candidate is nominated.” All additional nominees must fulfill nomination requirements as indicated in the ION Satellite Division Bylaws and the nomination must be received at the ION National Office by July 13, 2018.
Online voting for the ION Satellite Division Officers will be available after July 16, and completed ballots must be received at the ION office by August 6, 2018 in order to be counted.
Election results will be announced during the 31st International Technical Meeting of the ION Satellite Division being held September 24-28, 2018 in Miami, Florida.
The newly elected officers will take office on September 28, 2018 at the conclusion of the meeting and will serve for two years. Election results will be reported in the ION Newsletter.

The advent of the Internet of Things (IoT) has considerably increased the number of services and applications that require positioning information. In this sense, IoT positioning sensors usually obtain and deliver their position to a central node where it is further managed and analyzed by a user or scheduler. Nonetheless, the stringent requirements of low-cost IoT sensors in terms of low power consumption to achieve larger battery lifetime are pushing current technologies to their limits.

Xiaomi has launched the world’s first dual-frequency GNSS smartphone, the Mi 8. This smartphone represents a breakthrough in GNSS technology as it is the first commercial deployment of Broadcom’s revolutionary BCM47755 chip. It provides up to decimeter-level accuracy for location-based services and vehicle navigation, according tothe European GNSS Agency (GSA).

Broadgnss Technologies recently announced at the 9th China Satellite Navigation Conference a new high precision satellite position receiver with patented RAC（Real-time Array Calibration) technology. It features positioning accuracy better than one meter (up to 10 centimeters). By receiving only single frequency (GPS L1) satellite signals, the RAC technology in high precision satellite positioning frees the dependence on traditional augmentation network and significantly reduces the cost to enable high precision satellite positioning to enter large-scale applications, according to the company.
