GnssAntennaDefintionList

Provides a list of GnssAntennaDefinitions as used in GnssAntennaDefinitionCreate.

New

Creates a new antenna.

Name	Type	Annotation
name	string
serial	string
radome	string
comment	string
pattern	sequence
type	gnssType	pattern matching of observation types
offsetX	double	[m] antenna center offset
offsetY	double	[m] antenna center offset
offsetZ	double	[m] antenna center offset
deltaAzimuth	angle	[degree] step size
deltaZenith	angle	[degree] step size
maxZenith	angle	[degree]
values	expression	[m] expression (zenith, azimuth: variables)

FromFile

Select all or the first antenna from an antenna definition file which matches the wildcards.

Name	Type	Annotation
inputfileAntennaDefinition	filename
name	string
serial	string
radome	string
onlyFirstMatch	boolean	otherwise all machting antennas included

FromStationInfo

Select all antennas from an antenna definition file which are used by a station within a defined time interval. With specializeAntenna an individual antenna is created for each different serial number using the general type specific values from file.

Name	Type	Annotation
inputfileStationInfo	filename
inputfileAntennaDefinition	filename
timeStart	time	only antennas used in this time interval
timeEnd	time	only antennas used in this time interval
specializeAntenna	boolean	e.g. separate different serial numbers from stationInfo

Resample

The azimuth and elevation dependent antenna center variations (patterns) of all antennas are resampled to a new resolution.

Name	Type	Annotation

deltaAzimuth	angle	[degree] step size, empty: no change
deltaZenith	angle	[degree] step size, empty: no change
maxZenith	angle	[degree], empty: no change

Transform

This class can be used to separate general antenna patterns for different gnssTypes. If the antennas contain only one pattern for all GPS observations on the L1 frequency (*1*G**), the patternTypes=C1*G** and L1*G** create two patterns with the *1*G** patterm as template. The first matching pattern in the antenna is used as template. Also new additionalPattern can be added (e.g. for *5*G**). With addExistingPatterns all already existing patterns that don't match completely to any of the above are added.

Name	Type	Annotation
antenna	gnssAntennaDefintionList
patternTypes	gnssType	gnssType for each pattern (first match is used)
additionalPattern	sequence	additional new patterns
type	gnssType	pattern matching of observation types
offsetX	double	[m] antenna center offset
offsetY	double	[m] antenna center offset
offsetZ	double	[m] antenna center offset
deltaAzimuth	angle	[degree] step size
deltaZenith	angle	[degree] step size
maxZenith	angle	[degree]
values	expression	[m] expression (zenith, azimuth: variables)
addExistingPatterns	boolean	add existing patterns that don't match completely any of the above

Rename

Replaces parts of the descrption of antennas. The star "*" left this part untouched.

comment	string	*: left this part untouched

SetZero

The antenna center variations (patterns) or offsets of all antennas are set to zero.

Name	Type	Annotation
antenna	gnssAntennaDefintionList
patternTypes	gnssType	only matching patterns, default: all
zeroOffset	boolean
zeroPattern	boolean

RemoveCenterMean

The antenna offset and antenna variations (patterns) are inseparable parts of the antenna model. With removeOffset an estimated offset is removed from all selected patterns and added to the offset. With removeMean an estimated constant is removed additionally as it cannot be seperated from signal biases. The mean and offset are defined as discretized (deltaAzimuth, dZenith) integral of the spherical cap from zenith down to maxZenith.

Name	Type	Annotation
antenna	gnssAntennaDefintionList
patternTypes	gnssType	only matching patterns, default: all
removeMean	boolean
removeOffset	boolean
deltaAzimuth	angle	[degree] sampling of pattern to estimate center/constant
deltaZenith	angle	[degree] sampling of pattern to estimate center/constant
maxZenith	angle	[degree] sampling of pattern to estimate center/constant
