Set the Receiver’s to exclude satellites which appear below
a specified elevation angle.
At the factory, and whenever the Receiver is preset, the Receiver is set
to seek satellites 10 degrees above the horizon—down to an “elevation
mask angle” of 10 degrees. The 10 degrees setting provides a view of
most of the sky while avoiding near-horizon satellites, which are more
susceptible to atmospheric anomalies and multi-path effects. The
Receiver can be custom-configured to use a different elevation mask
angle.
Set the Receiver elevation mask angle using the command:
:GPS:SAT:TRAC:EMANGLE
<
degrees
>
Set the Receiver’s to display local time rather than UTC
time.
Set the offset from UTC time to local time using the command:
:PTIME:TZONE
<
hours
>, <
minutes
>
To Install With a Limited View of the Sky,
To Bypass Position Survey Operation
In order to operate properly, the Receiver must know its position. The
Receiver is able to collect enough information from four satellites to
compute this position. The “position survey operation” takes in data
from the satellites, iterating until the antenna position is known to the
required precision. The Receiver will automatically use its position
survey operation on powerup and
:SYSTEM:PRESET
.
Alternatively, if the antenna position is already known to seconds of
arc, and the Receiver cannot see enough satellites, you may manually
enter antenna position as shown in the following text.
NOTE
An incorrect value for the position will confuse the Receiver, and will
degrade the timing information accuracy or even prevent tracking any
satellites.
Set the Receiver antenna position using the command format shown
below (For clarity, an example is provided rather than a complex
description.):
:GPS:POS N,37,19,32.5,W,121,59,51.2,40.12
