Interactive Command Set
336 SSU-2000 User’s Guide 12713020-002-2 Revision D – April 2004
Remarks
ELMASK Default values for the masks are 5 degrees for the
positioning mask and 10 degrees for time.
POS Only set the position if you know the accurate position.
The software automatically verifies the position on
restart. The unit averages 10 position fixes and
compares them to the fixed position.
If the position is within 100m RMS, no position updates
are performed. If the position error is > 100m RMS, an
event is generated stating that the position is being
recalculated, and the position is recalculated and
updated in the NVRAM. Similarly, setting the AVG time
puts the unit back into survey mode, which generates
an event that the position is being recalculated.
TDATA Engine reports are asynchronous outputs, which means
they can occur at any time, not necessarily at the time
the command is issued.
