Chris,
Yes, you told me last week. I did it again today but still not work. Let me
say about the history.
2 weeks ago trainer (Steve Zest) and I walked outdoor but we were puzzled
the heading was not work. We tried it again and again.
Last Thursday we went to the store about 3 blocks from my home but heading
was not work.
Last Friday I walked 23 blocks but heading was not work.
Since I tried the different features but only one heading is not work.
WIELD: I left my PK and GPS on the shelves. Later Heading display changed
from Unknown to "s 285 degree". But it display kept to change as "ghost"
walk or drive away from here. No wonder because the devices sat on the
shelf.
Leslie--

Hello Lesley,
GPS is not a compass. you must be moving for around 30 seconds or more for
the GPS to obtained your heading. This is a limitation of gps. If you have a
fix and are sitting in your room with a heading unknown and spin around in
circles for 3 days your heading will still be unknown the next time you
check. Once you start to move in a specific direction you will get a
heading. If you can send me a replay file off-list so I can see exactly what
your gps receiver is sending your BrailleNote. to do this press space with
Q. You are prompted for the drive, then the folder then the file name.
Place it in a folder and a file that you will remember. after you go for
your walk and your receiver has not given you a heading for at least 5
minutes send the replay file to chris@xxxxxxxxxxxxxxxx Just a quick note
about the force your heading feature ENTER with H BT READ with H QT. You
would use this feature if you are sure the direction you are going, this is
temporary until your GPS takes over and gives you a true heading. This is so
you can see where pois and things are relative to the direction you should
be going.
Here's an example.
My street runs east/west. I want to go to a store that is south west of my
house. I turn on the GPS receiver walk to the end of my driveway and receive
heading unknown. (the receiver has not gained a heading because I have not
moved far enough, but I know I will be heading down my street west. I use
the ENTER with H command to force the system to think I'm going west. I
then check my destination with the D key. My destination is reported as 0.2
miles slight left.
If I had not forced the system it would report my destination as 0.2 miles
South West.
Hope this example is clear why one would use the force GPS heading feature.
Thanks Chris
