The time and initial position controls help the unit to obtain
satellites faster in a new geographic location or when there is
no almanac data present on the unit.
Time/Date and position controls can be edited by selecting
8. Setup, 2. Hardware Management, GPS, Initialization.
)
New almanac data is sent by a satellite every 12.5
minutes. This can mean that it may take a maximum of
25 minutes depending when the first satellite is
collected. After the first position is calculated, the Time
and Initial Position fields will update to reflect the last
position.
Remember: Valid limits are 0-90 degrees for Latitude and
0-180 degrees (East and West) for Longitude.
9.7 Data Collection
The Data Collection subgroup is where quality minimums are
defined for both automatic collection and notification alarms.
9.7.1 Quality Monitor
The Quality Monitor controls are subdivided into Point Quality
(which is also applicable for linear node collection) and Line/
Area streaming.
Point Quality
1. Defined By: Horizontal, Vertical, Horizontal & Vertical, or
None.
)
If only Horizontal or Vertical quality is chosen, the other
edit field will be disabled!
2. Point Autostop:
• None: Occupation is manually controlled (i.e. started
and stopped) by the user.
• Quality: The occupation will be stopped once the
Quality defined (e.g. Horizontal) is achieved.
• Positions: The occupation will be stopped once the
number of positions required are collected.
)
Positions must achieve the required quality to be
stored.
