Set up u8 antenna orientation
When in motion, the antenna’s yaw (heading), relative to north, is provided by the GPS heading. The Kymeta u8 antenna
out-of-the-box configuration assumes that the X axis of the antenna is aligned with the heading vector of the vehicle. If
this is not the case, you can set the vehicle-to-ant-yaw value to inform the antenna of the offset. Set the offset correctly
to expedite acquisition of the satellite while in motion.
✎
If the offset is not set or is set incorrectly, the antenna can acquire the satellite, but it may take longer and will
result in more out-of-network time.
In the figure below, the antenna is correctly aligned, using the antenna’s default value of zero.
✎
Make sure the Kymeta logo is front-facing and the fans are facing towards the rear of the car.
For an unaligned antenna, set vehicle-to-ant-yaw to the angle between the X axis and the heading vector as in the figure
below. The range is from -360° to 360° with positive angles representing a clockwise rotation of the antenna from the
vehicle heading vector.
