Excludes unknown-position sats from skyview displays.
In some cases, the elevation and azimuth information are missing
(i.e., reported as 0) for some satellites. E.g., the Navika-100
receiver fails to report positions for SBAS satellites. This change
avoids showing such satellites at the "north point" of the display.
They are *not* excluded from the textual list.
TESTED:
Ran xgps, xgpsspeed, and webgps.py against data from a Navika-100
receiver, and verified that the SBAS satellites are no longer
inappropriately shown at the top.
