THE SYSTEM eLoran Continued from previous page where oil laden vessels come from deep sea drilling rigs Entirely independent of GPS eLoran can provide navigation information for vessels as well as the timing data necessary to maintain the power grid cell phones financial networks and the Internet in the event of an outage Unlike space based navigation eLoran signals can also reach inside buildings underground and underwater Captain Ian McNaught deputy master of Trinity House commented eLoran provides a signal around 1 million times more powerful than those from satellite signals providing resilience from interference and attack The achievement of initial operational capability for the system at Dover and along the east coast of the UK is a significant milestone providing for improved safety aboard appropriately equipped vessels The maritime industry would now benefit from the installation of eLoran receivers on more vessels to take advantage of improved navigational safety Telecoms finance energy and other industries which are subject to significant issues caused by the loss of timing signal provided by GPS are recommended to take advantage of the enhanced reliability now available to address the over dependence of key national infrastructure on vulnerable satellite systems McNaught said eLoran technology is based on longwave radio signals and is independent and complementary to GPS Several other nations are consulting with the UK GLAs 28 B I L L I O N A u e g th geospatial indust y Can This is 20 of the global market Welcome IIF 8 The U S Air Force launched the eighth GPS IIF satellite on October 29 aboard an Atlas V 401 rocket With this new arrival on orbit only four more Block IIF satellites remain to be placed aloft Three are in storage awaiting launch and one is in production The Boeing built GPS IIF 8 SVN 69 PRN 03 will replace SVN 51 in the E plane slot 1 SVN 51 will be rephased from E1 to an auxiliary node at E7 somewhere around SVN 54 currently on station at E4 according to the Air Force Second Space Operations Squadron 2 SOPS SVN 38 PRN 08 will be taken out of the operational constellation prior to SVN 69 payload initialization and sent to Launch Anomaly Resolution and Disposal Operations LADO PRN 08 will be assigned initially to SVN 49 and set to test SVN 51 will remain in an auxiliary node once it completes its re phase journey The SVN 51 re phase will take about six months after the initial burn occurs on eLoran South Korea wants to establish an eLoran alliance with the UK while it pursues its own rollout of differential eLoran reference stations and new eLoran transmitters based on the latest technology In 2012 South Korea was the victim of a 16 day GPS jamming attack by North Korea Full operational capability covering all major UK ports is expected by 2019 If you are looking to be a part of this growing Canadian industry Lethbridge Alberta is an excellent choice As a hub for geospatial technologies Lethbridge is known for its specialization in remote sensing imagery and GIS With a robust business environment two post secondary institutions a vibrant entrepreneurial ecosystem and a welcoming community flled with arts culture and recreation opportunities Lethb dge is a great choice for you and your business Connect with us @ chooseleth geo@ chooselethbridge ca tecconnect ca chooselethbridge ca GPS World December 2014 www gpsworld com 10
