With a recent report predicting that consumer and precision GNSS receiver IC shipments will reach two billion units by 2016, it is important to remember that quantity must be underscored by quality. The report, by ABI Research, highlights the importance of new vertical markets, such as tablets, cameras and fitness equipment, as well as the growth of LBS (location-based services) and LBA (location-based advertising) applications, all of which will contribute to a quadrupling of the market wit...

GPS and inertial sensors complement each other extremely well. GPS works best with a good view of the sky. When the sky view gets obstructed, for example in an aircraft roll or when a smartphone gets taken indoors, GPS will not continue to track and the navigation capability is lost. Inertial sensors continue working in all conditions – move them and you get an output from the sensor. The biggest weakness of inertial sensors is that errors are cumulative. By combining GPS and ine...

Over the past few years the ability of consumer grade devices, typically smart phones but also PNDs, to navigate indoors has improved significantly. This is because GPS has been supplemented by other navigation technologies, such as cell tower identification and, more recently, navigation using Wi-Fi to localise position. To get reliable sub-10metre accuracy indoors, however, will require more than GPS, cellular and Wi-Fi positioning. Use of other sensors, particularly MEMS inertial se...
