InvenSense licenses inertial navigation tech to Huawei

December 11, 2015  - By

Huawei has licensed the InvenSense Positioning Library (IPL) software sensor-assisted positioning technology for incorporation into the Kirin 950 mobile application processor platforms by HiSilicon.

InvenSense is a provider of micro-electro-mechanical (MEMS) sensor platforms. The recently launched Huawei Mate 8 smartphone is the first model to incorporate the HiSilicon and IPL technology.

IPL improves smartphone GNSS-only implementations by providing more continuous and accurate navigation in areas with poor GNSS signal quality. The IPL solution delivers sensor-enhanced positioning providing a high-availability, high-accuracy turn-by-turn navigation user experience to HiSilicon mobile platforms and mobile application developers.

Through this collaboration, InvenSense and HiSilicon will make continuous improvements to IPL and the overall location subsystem to provide the best possible navigation experience to Huawei’s customers.

The combination of sensor positioning with GNSS enhances navigation user experience by eliminating “GPS Signal Lost” warnings and unnecessary re-routings in map applications due to GNSS multipath errors. IPL uses complex algorithms that take sensor data from the mobile device gyroscope, accelerometer, magnetometer and barometric pressure sensors to generate an inertial navigation system (INS) that tracks the position change of a vehicle or pedestrian.

IPL then combines the INS with GNSS to provide always-available and more accurate location data when GNSS is inaccurate or unavailable, such as in deep urban canyons with tall buildings or in tunnels and parking garages. IPL operates in any physical orientation allowing the user to freely move the phone in the vehicle during active navigation sessions.

“Today’s consumers are increasingly using smartphones for turn-by-turn navigation in vehicles, creating a strong need for a higher quality user experience that decreases the occurrence of confusing or stressful re-routes and GPS lost signal messages,” said Eitan Medina, vice president marketing and product management at InvenSense. “We are pleased that HiSilicon, a market leader in end-to-end chipsets and solutions, has chosen our IPL technology for integration into its mobile platforms.”

IPL is available now for smartphones using Android, iOS, Windows and general Linux operating systems.
