iGage iG9 User Manual
'Default HI'
When you download an occupation from the receiver, this HI will be the default associated with
every occupation. You can change the HI for each individual occupation later, this is just the default.
If you ALWAYS use a 2-meter range pole, then this value will always be 2.000 and you won't have to
worry about HI blunders.
FEET: If you measure up in feet, you can enter the height in decimal feet and put an 'F' after the
measurement. The program will automatically convert to Meters for you.
SLANT HEIGHT in Meters
: If you measure a slant height, enter an ‘S’ after the measurement and the
program will compute the vertical height for you.
SLANT HEIGHT in FEET
: If you measure a slant height in feet, enter ‘SF’ or ‘FS’ after the
measurement and the program will compute the vertical height in Meters for you.
Note: if you use the ‘PPP Service’ = ‘RTX (CenterPoint)’ t
he submitted RINEX file spoofs an
‘UNKNOWN EXT NONE’
and adjusts your actual HI to reflect the generic antenna L1 offset.
'Default Agency'
Enter your company name here. This value is placed into every RINEX file that is exported. You can
override this value on a file-by-file basis.
Typically, the Agency name is two to five characters with no spaces. While most strings up to 20
characters in length will be accepted, you may cause issues with other programs that consume
generated RINEX. It is safest to keep this short with no special characters.
'Default Operator'
Enter the default name of the operator here. This value is placed into every RINEX file that is
exported. You can override this value on a file-by-file basis.
Typically, the Operator name is two to five characters with no spaces. While most strings up to 20
characters in length will be accepted, you may cause issues with other programs that consume
generated RINEX. It is safest to keep this short with no special characters.
'Decimate OPUS Submission to ...'
(Hidden when Simple)
When you submit a file to OPUS, it is always decimated at the NGS server to 30-second epochs
(recording interval = 1 point every 15 seconds.) The default recording interval for most iGage
receivers is 1 or 5-seconds.
By pre-decimating the RINEX file before upload, it is reduced to 1/6
th
to 1/30th the original size. This
makes the upload process much faster while having no impact on the resulting solution.
Observations submitted to RTX are not decimated, AUSPOS submissions are decimated to 15
seconds. Observations exported directly to RINEX
using the ‘
Export RINEX
’ button
are never
decimated.
