Adjusting satellite elevation
You can prohibit the tracking of satellites that are close to the
horizon and don’t provide high accuracy. The tracking of low
satellites during GPS calculations is used primarily for
technical applications, in which all visible satellites must be
tracked, regardless of how low they’re situated.
In other cases, however, when high-precision fixes are
necessary, the advanced user can change this option to hide
any low satellites. This option prevents the use of low satellites
as sources of GPS position information, and avoids potential
errors.
You can adjust this option to 0°, 5°, 8°, 10°, or 15°; however,
Northstar recommends that you leave this option at the
factory setting of 10°.

1. At the
RECEIVER INFORMATION
