WAAS 35 Moving (Another Reset?)

Now that 35 is moving on 2/1 does that mean that when it arrives I'll =
need another reset on my Garmin 76S? I hope not. It will arrive at it's =
new position by 4/1. When it does it might be stronger than 47. Then I =
might want 36 and 35 as my WAAS sats. But because of Garmins firmware =
once I lock on 2 sats it won't look for anything else unless I reset it. =
My 2 favorite WAAS sats now are 36 and 47. I guess to test the new 35 =
I'll have to reset unless there is some way of knowing the above the =
horizon elevation of 35. They mention the move to 142 degrees which is =
good for US but the elevation looks low. I don't mind a reset it's just =
that with all these sats now I wonder how GPS units will deal with all =
this. We will have a choice of 4 different sats when this is said and =
done. So my theory is that in a few months I will do another reset and =
let the strongest signals win! Unless Garmin comes up with a firmware =
update to allow reaquire of WAAS then this will be my plan. I foresee my =
WAAS ending up being 36 & 47 or 36 & 35 depending on 35's new above the =
horizon position.

It shouldn't require a reset, but of course I can't make any guarantees
about how well the firmware handles the addition of new WAAS
satellites.

Each WAAS satellite sends out almanac data on the orbital positions of
all the WAAS sats. So once the receiver has a good lock on one of the
satellites and has gotten the complete data message then it should know
where the others are and just look for the ones that are highest in the
sky.

Note that 36 is still in test mode, so the fact that you had to do a
reset may not be indicative of the situation when a new WAAS satellite
becomes operational. A friend who has not done any resets of his
Garmin 60cs model observed today that it had automatically switched
from looking at 35 & 47 to 36 & 47 so your 76S may well have done the
same if left for another day.

OK-I'm glad you told me that. I always feel sometimes I'm missing out if =
I don't see it. So next time when 35 moves over I'll take your advice =
and see if the almanac will switch it. I don't really like having to =
reload all my waypoints anyway!

You understand that 36 is only being used during the testing phase of
the Galaxy 15 satellite, and that when it becomes operational it will
have another number, right?

I have not heard that. I guess I'll just keep checking as these things =
move around over the next 60 days and let my Garmin pick out what it =
likes. I'm sure we will have many posts and threads on all of this as =
the next 60 days passes.
