Figure 6-5 3D search time mode

The GeckoSynco will start acquisition and averaging of the 3D coordinates.

It may take some time to get usable values and the coordinates are all shown as

‘invalid’ during this period. When values are shown, they are color coded to

indicate 3D precision, starting from red to yellow to green. When the color is in

green, it means that the coordinates are accurate within 2 meters, and is ready to

go into ‘Fixed’ mode. This process takes 1~3 days, and the longer period you wait,

the more accurate they get.

When the coordinate values are green, click Use Mean to move the

coordinates to the lower part of the page, the Time Mode changes to ‘Fixed’ at the

same time. Click Apply to take effect.

Note

3

the coordinates should be accurate within a few meters to keep the time error within

specification. Every meter-off results in a phase error of about 3ns.
