LEAPSECOND
Syntax:
yyyy mm dd LEAPSECOND
Manually notify the digitizer of an upcoming leap second. This
command is not normally necessary, since GPS already has
support for leap seconds. However, some units do not properly
interpret the GPS signals. See
SQPATCH
, below.
The leap second is taken to be at the end of the day
yyyy - mm -
dd
.
SQPATCH
Syntax:
SQPATCH ENABLE
or
SQPATCH DISABLE
Enables or disables the internal patch for older GPS receivers
based on Trimble Lassen SQ units. These units misinterpret the
GPS system's advance notification of a leap second, and
consequently run one second slow until the leap second occurs.
With
SQPATCH
enabled, the time reported by the digitizer is
offset by 1 second to counteract this problem. If you have set
LEAPSECOND
, above,
SQPATCH
will automatically be disabled
when the leap second occurs, and the digitizer will then run
normally.
GPS receivers with the latest firmware do not suffer from this
problem.
To find out whether
SQPATCH
is currently enabled, issue the
command
.SQPATCH
BAUD

port baud-rate BAUD

bytes per second.
port
can be
•
0
, for the

port, or
•
1
, for the GPS port.
