GPS Vector Data

Imported vector information (including any base and rover antenna heights) supplied on G1, G2 and G3 data lines will always be in Meters whether or not the project is setup to run in Meters. When the project is setup to run in other linear units, for example FeetUS, vector information is automatically converted to project units for calculations and output in the listing file.

Standard Errors

A "standard error" is a value used to weight an observation. When you enter standard error values on a data line, they always directly follow the group of observations, one standard error value for each observation. A standard error may be entered as a numeric value or as a special symbol. The following table explains the various entries.

Blank If no standard error values are given, the instrument settings will be used to weight the observation.
& This symbol tells STAR*NET to apply the standard error settings from the instrument settings. This symbol is usually not necessary unless you need to mix project default standard errors with other types of standard error input.
! "Fix" an observation - Observation will not be adjusted.
* "Float" an observation - Observation will be treated as an initial input value and will carry no weight during the adjustment.
Numeric Value The numeric standard error value will be applied as the standard deviation for that observation alone.
  Examples
C  100 1000.000 1000.000 100.000 'Description
# Coordinate input for Point 100 are assumed to be free for adjustment

C  101 1000.000 1000.000 100.000 !!! 'Description
# Coordinate input for Point 101 will be held "fixed"

C  102 1000.000 1000.000 100.000 .01 .01 .01 'Description
# Coordinate input for Point 102 will be given the standard deviation of .01 units

C  103 1000.000 1000.000 100.000 !!* 'Description
# X, Y values for Point 103 will be held "fixed" but the Z value will "float"

M  1-2-104 80-00-00 123.456 90-00-00 &&* 1.23/1.45 'Description
# Angle and Slope Distance in this M record will be weighted as per project
# settings but the Zenith will "float" so it has no weight in the adjustment
