If you intend to use the observation files with OPUS you
must use one of these recording intervals:
1, 2, 3, 5, 10, 15 or 30 seconds
Auto Sessioning
The default 'Auto Sessioning' setting is 'NONE.’ Some
applications may benefit from having the receiver
automatically close files after a preset period.
‘Auto Sessioning’ only closes the current file. A new file is
not automatically opened.
Elevation Mask
The default setting for ‘Elevation Mask’ is 0 degrees. All
visible satellites are tracked.
OPUS automatically ignores satellites lower than 10-
degrees.
There is a benefit to having the receiver track satellites for
as long as possible as they rise to 10-degrees. (We don’t
want to start tracking at the exact moment that OPUS
begins to use the satellite.)
The internal memory of the receiver is huge. There probably
is no advantage to raising the tracking elevation for any
application and it is recommended that you keep the
tracking angle set to the default 0-value unless you have a
really good reason to change it.
Update Firmware
Updating the firmware in your receiver requires that the
GPS be connected to a COM port on your computer (COM1
is best) and that your computer has an active internet
connection.
