As it is a direct angular measurement it does not suffer drift over time.

A numerical representation of position quality, present when IMU integration is enabled. This heading will be the ‘course over ground’ bearing at the antenna location with respect to North, irrespective of vehicle direction. UTC is the universal coordinated time, which is accurate to about a nanosecond (billionth of a second) per day. Lists the total number of GPS satellites the unit is currently tracking in the solution. Accelerometer measurement in the vehicle lateral plane, +ve for counter clockwise rotation. Accuracy of the current GNSS horizontal velocity measurement. If you want to quickly find the pages about a particular topic as lateral acceleration use the following search engine: What does it mean lateral acceleration explanation, Free dictionary of technical engineering Terms, Meaning and definition of lateral acceleration, Glossary of technical and automotive terms, Larapedia.com Terms of service and privacy page. This channel contains the raw GNSS data from the Doppler derived GNSS Heading. When mounted on a vehicle it becomes the measurement of heading that the vehicle is facing.

In the case that GNSS signal is lost the IMU will continue to provide vertical speed data however this will degrade in accuracy over time. Did you know? Head_imu2 is the heading of the body of the vehicle generated by the Kalman filter utilizing alignment algorithms and using GNSS and Inertial data. If you are the author of the text above and you not agree to share your knowledge for teaching, research, scholarship (for fair use as indicated in the United States copyrigh low) please send us an e-mail and we will remove your text quickly. Also in the case that GNSS signal is lost the IMU will continue to provide speed data however this will degrade in accuracy over time. This channel has a very high height accuracy over short periods of time and is resilient to satellites appearing or disappearing . Latitude is an angle produced in the GNSS engine using trilateration of satellite time signals from four or more observable satellites. As it is a direct angular measurement, it does not suffer drift over time. In the case that GNSS signal is lost the IMU will continue to provide height data however this will degrade in accuracy over time.

Meaning of lateral acceleration . Lateral means relating to the sides of something, or moving in a sideways direction.
