All satellites above the default

minimum elevation of 15 degree

should be tracked.

Tracked satellites will show signal

strength values between 32 and 51

(SN1 and SN2 - Signal / Noise values

on L1 and L2). High elevation

satellites should have values

between 45 and 51. Low elevation

satel-lites (elevations below 20

degree) will show values between 32

and 40.

Not tracked satellites are shown with

a dash line instead S/N values.

The measurement quality is indicated

with numbers of up to 99 in the QI1

and QI2 column. Values will usually

vary between 80 and 99. Lower

values indicate disturbed signal

reception, for instance caused by

trees, leaves, or very active

atmospheric conditions.

If you find satellites above 15 degree

which are not tracked then the line of

sight between the antenna and the

satellite is most likely blocked by

obstructions.

If more than 6 satellites are in view

you have to use the cursor down / up

keys to scroll up and down the

screen and get the information on

those satellites which do not fit onto

the same screen.

Satellite status

For each satellite the following

information is provided:

• SV number
• Elevation and azimuth
• Signal strength on L1 and L2
• Quality indicator for L1 and L2

measurements

This panel provides valuable

information on the current

performance of your sensor:

Select "1 Survey" \ "5 Satellite". The
