4.2 GNSS Menu
Settings
Leap Second The leap second value can be changed if required. This was increased to 18 seconds as of December 2016 - you can find more information about leap seconds here.
Elevation Mask Allows you to change the elevation mask, selectable from 10 to 25° (10° by default). If the testing area has nearby trees or buildings, you may benefit from increasing this value to reduce the effect of multipath. More information on this is available here. Note: Increasing this value will reduce the number of satellites the VBOX will be able to use. |

Engineering diagnostics
The Engineering Diagnostics tab contains information about the connected VBOX unit and the GNSS engine. This is also where you can coldstart your unit.
By pressing the GNSS coldstart button, you can reset the GNSS receiver and clear the last known position and almanac.
