Inertial Ranging eLoran Wi Fi Bluetooth Iridium Constellation Provides Low Earth Orbit SatNav Service A strategic alliance announced on Dec 15 between Orolia and Satelles includes product development and go to market activities of positioning navigation and timing PNT solutions provided by the Iridium satellite constellation independent of GPS GNSS signals The companies intend to provide PNT solutions to military defense government and commercial customers worldwide Orolia the parent of GNSS active companies Spectracom and Spectratime among others has formed a strategic alliance including an equity investment with Satelles Inc to develop market and sell PNT solutions based on Satelles satellite time and location STL signal technology STL is a unique space based PNT technology that provides location and timing data independent from traditional GPS and other GNSS satellite signals By using STL Orolias Spectracom and McMurdo solutions will according to the company be less susceptible to vulnerabilities such as spoofing interference and jamming that are associated with GPS GNSS Based on the low Earth orbit LEO Iridium satellite 14 GPS WORLD WWW GPSWORLD COM JANUARY 2017 constellation STL signals are up to 1000 times stronger than GPS GNSS this signal strength due in part to the constellations closer proximity to users helps to prevent jamming and enables signal reach into buildings and other difficult locations STLs additional cryptographic security also ensures performance productivity and security For further background on Iridium see GPS Worlds June 2016 Defense PNT column at gpsworld com junedefense Iridium and GPS revisited A new PNT solution on the horizon Projected applications and use cases include energy utility grids enterprise data networks including financial systems maritime aviation navigation fleet asset tracking management search and rescue and data center management Many highly sensitive military defense government and commercial applications and operations require accurate and reliable PNT data Today these applications rely on signals from GPS GNSS satellites There are instances however where GPS GNSS signal strength and security are not sufficient and prone to signal disruption For these cases the companies jointly state STL can be used as a secure SATELLITE TIME LOCATION Iridium satellite Image Iridium
