Description

The GNSS_BREADCRUMBING_PARAM structure contains the configuration passed into the start of breadcrumbing via IOCTL_GNSS_START_BREADCRUMBING.

Members

Size

Structure size.

Version

Version number.

MaximumHorizontalUncertainty

Contains the maximum horizontal uncertainty value. Any fix with an error radius larger than this value shall not be recorded.

MinDistanceBetweenFixes

Contains the minimum distance between fixes. Only record a fix if the center of it is at least as far apart as this value from center of the last fix, using a Haversine distance calculation.

MaximumErrorTimeoutMs

Contains the maximum error timeout in milliseconds. If the location of the device is unknown for this duration, an error must be recorded in the breadcrumb data. Errors can be recorded earlier if they were already known.

Unused

Padding buffer reserved for future use.
