The third tab, as its name implies, deals with the WAAS/EGNOS satellites (Figure 32).
Figure 32. “WAAS” tab
A WAAS-enabled TPS receiver allows simultaneous tracking of two WAAS satellites. Either of the
WAAS satellites is allocated its own channel. Below it will be shown how to set up Channel 1
(Channel 2 is handled in the same manner).
The checkbox
Channel 1
, if selected, allows you to specify necessary settings for the desired
WAAS satellite.

One uses the spin-boxes
Set WAAS
and
as GPS
to associate the selected WAAS
PRN (120-138
17
) with an appropriate GPS PRN (1-32). It is recommended to select for
this purpose one of the GPS PRNs that are not used in the current GPS constellation. At
writing this manual, the unused GPS PRNs are: 12, 16, 19 and 32. The spin-boxes cor-
respond to the receiver parameter
/par/waas/1/sat
.

The spin-box
Interpret message #0 as message: #
disables message 0.
The corresponding receiver parameter is
/par/waas/1/instead0
