Projected accuracy and coverage of Korea’s eLoran network. Ministry of Oceans and Fisheries of KoreaGPS jamming attacks from North Korea that have increased in frequency and duration since they began August 2010 have prompted the South Korean government to implement an enhanced Loran (eLoran) systems that will cover the entire country by 2016.
The South Korean government completed design, development, and construction documents for the eLoran system in February and will procure the system infrastructure through international competitive bidding.

Spending pressures on the Pentagon seem to be coming from every direction, and the GPS program appears unlikely to avoid them entirely.
The growing needs of veterans are poised to force up health care budgets and higher transportation costs and operating tempos have dug a $22 billion-hole in the accounts for Overseas Contingency Operations in places such as Afghanistan.

The U.S. Insurance Institute for Highway Safety will use Locata positioning to control automated testing of frontal collision avoidance and other safety systems. IIHS imageIn announcing the selection of its terrestrial positioning system as the core PNT technology for the U.S. Insurance Institute for Highway Safety (IIHS) Vehicle Research Center (VRC), Locata Corporation has opened up a new front in its campaign to augment or replace GNSS in application environments where the latter technology is unreliable or unavailable.

The International GNSS Service (IGS), a worldwide federation of agencies involved in high-precision GNSS) applications, has announced the launch of its Real-Time Service (RTS).
The RTS is a global scale GNSS orbit and clock correction service that enables real-time precise point positioning (PPP) and related applications requiring access to IGS low latency products. The RTS is offered in beta as a GPS-only service for the development and testing of applications.

The 2013 Unmanned Systems North America industry exhibition and symposium sponsored by AUVSI will be held from August 12 -15 at Walter E. Washington convention Center in Washington D.C. The Renaissance Washington is the conference headquarters hotel.
It features technical panels and presentations, workshops and poster sessions on the state of the unmanned systems and robotics markets. The event covers military, civil and commercial applications for air, ground and maritime vehicles.
Furuno Electric Company has announced that new multi-GNSS receiver chips eRideOPUS 6 and eRideOPUS 7 — with active anti-jamming, multipath mitigation, and dead reckoning interfaces — will be available to the market beginning August 2013.
The eRideOPUS 7 receiver chip can process GPS and GLONASS signals (with a combined antenna), satellite-based augmentation system (SBAS) transmissions, Japan’s Quasi-Zenith Satellite System (QZSS), and — with a software update —Galileo signals. The eRideOPUS 6 is not GLONASS-capable.
