TDK Corporation has launched its InvenSense Coursa Drive software, an inertial-aided positioning solution for autonomous vehicle platform developers.
A high-performance extension of the InvenSense Positioning Library (IPL) that has provided sensor-aided positioning to more than 50 million devices worldwide, Coursa Drive enhances inertial-only vehicle positioning to <0.2 percent of distance traveled. These precise levels of accuracy are critical to maintaining decimeter lane-level vehicle positioning in challenging GNSS/perception system environments.
Coursa Drive’s inertial navigation system (INS) calibrates using absolute position inputs from either high-accuracy GNSS receivers or from perception-based systems (camera, radar, lidar) with high-definition (HD) maps.
In real time, Coursa Drive provides high-rate, 100 Hz delta positions and orientation to the autonomous vehicle (AV) system, complementing the lower-rate position references from GNSS and perception systems.
For improved system fault-tolerance, Coursa Drive can provide decimeter position precision for short periods when the GNSS or perception systems are uncertain or unavailable.
For non-real-time applications such as HD map creation and maintenance, Coursa Drive’s offline mode reprocesses INS data at two to three times higher accuracy than real-time mode, providing HD map companies alternative position references to verify HD map accuracy, even without GNSS, for up to 60 seconds.
“Coursa Drive delivers vehicle dead reckoning accuracy equivalent to high-end systems costing thousands of dollars,” said Mike Housholder, senior director of the TDK InvenSense Location Software and Services Business. “Our cost-effective software solution will help AV platform and Tier 1 vehicle manufacturers scale beyond prototype vehicles to high-volume mass production.”
Coursa Drive provides autonomous vehicle platform developers with maximum flexibility for system integration. The solution is platform agnostic and can operate on Cortex-M4F-class microcontrollers, or higher, and supports most dual-frequency GNSS receivers. The Coursa Drive API specifications are available upon request.
Coursa Drive is thoroughly tested and characterized using the InvenSense line of automotive-grade IMUs, including the IAM-20680 and IAM-20680HP, as well as several industrial grade IMUs. Coursa Drive is available now for select early partners and customers.
TDK and its group companies offering a comprehensive portfolio of sensors, electronic components and solutions for mobile, wearables, AR/VR, automotive, IoT and industrial applications will be at CES 2019, showcasing the Coursa Drive solution, along with additional innovative sensor solutions, in Booth #30306, Las Vegas Convention Center, South Hall 3, Jan. 8-11, Las Vegas.

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 Huawei Mate 8 smartphone is the first model to incorporate Invensense MEMS technology.
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.
