Accurately Tracking Smartphones IndoorsIf we wish to obtain consistently usable positions indoors using a mobile phone, we can augment its GPS or GNSS receiver with other unfettered sensing technologies such as gyroscopes and accelerometers supplemented by radio signals of opportunity. But is all of this actually feasible? The authors have conducted tests of a multi-system approach to positioning indoors with favorable results.
Despite the continued decline of PNDs, and the threat of smartphones, smart watches and eyewear, the portable GPS-enabled […]
Driven by increased demand from developed regions for high-end models, along with an unexpectedly strong push from emerging economies for lower-cost products, smartphones are expected to rise to account for the majority of global cellphone shipments in 2013—two years earlier than previously predicted, according to research firm IHS iSuppli.
Chronos Technology, a specialist supplier of GNSS (GPS, GLONASS, and Galileo) products and services, welcomes the decision by the UK regulator Ofcom on June 20 to implement a licensing regime for the use of GNSS repeaters in the UK. GNSS repeaters provide coverage for the use and testing of GNSS technology inside buildings where the GNSS signals do not normally reach. Until the recent decision by Ofcom, the use of this repeater technology in the UK was not permitted except in specialized (normally military) situations. Large numbers of consumer and industrial products use GNSS technology for positioning and timing applications including smartphones, telematics equipment, avionics and emergency service applications. GNSS technology can also be used for resource management, civil engineering and military applications.
