receiver will be allowed to start the sessions on the current
day, according to the programmed sessions.
For example, with
Reference Day
=33 (Feb 2), if the current
day is 30 (Jan 30), the receiver will start the first session
only in three days, whereas if the current day is 51 (Feb
20), the receiver will start the programmed sessions on
that day.
If you do not need to postpone the execution of the
sessions, keep the default value (“1”) for this option.
•
Offset per Day
(in minutes and seconds): This option is
specifically designed for users who wish to have the same
sky view of the GPS constellation every day. As the time
when the GPS constellation comes back to a given sky
view is 4 minutes earlier every day, setting this option to
04’00” will correct for this offset (i.e. this will allow the
same GPS sky view to be observed every day through each
of the sessions).
With
Offset per Day
=4’00”, a session initially set to start at
9:00 for example will start at 8:56 on the second day, at
8:52 on the third day, etc. The same rule applies to the
session end time, and to all the other programmed
sessions.
If you do not need to offset the sessions, keep the default
value (0’00”) for this option.
Raw Data Types
and Files Collected
During Sessions
The types of raw data collected during sessions are those you
have set on port S (for session batch #1) or port N (for session
batch #2). In addition, the amount of collected raw data is
tied to the value you give to
Raw Data Elevation Mask
) (See
Receiver
>
Satellites
on the Web Server).
Raw data are saved as
G-files
, using the same naming
convention as the one used in manual recording. A specific
Site Name
can be defined for files recorded through sessions.
The file naming convention used is given below:
G<SiteName><Index><Year>.<Day>
Example: GPT12C17.030 is the third G file (C) collected on Jan 30, 2017 on a
site named PT12.
