Scott, The orientation of the reciever itself doesn't matter but you will get a lot more accurate information if the receiver is situated at or above the shoulder as it has a clear view of the sky. This is recommended over having the reciever in a purse, pocket or even clipped onto a belt as this requires for the signals to penetrate the material resulting in signals bouncing from your body and material. This will not eliminate the issues of multi-path and drift but will reduce it. To read more about GPS signal issues in regards to multi-path and drift, I would recommend reading the GPS Accuracy documentation found in the 42docs.zip at MySendero.com. This is a very thorough document written by Charles LaPierre and Mike May explaining the way GPS and GPS Signals work.

For example, many receivers are flat, sort of match box shaped devices. It can sit on a table top and be "right side up" or if you carry your receiver could be anywhere. (bag, shirt pocket, glued to your head) How critical is that? If the receiver were fitted inside a hat oriented to face the way the user is walking how much or is it at all better than say if it sits in the shirt pocket. Did I read correctly that the Sendero suggested config is to have the receiver fitted in to a shoulder strap? I'm a little curious how that works, any pointers would be appreciated. Thanks P.S. I get how it's important to be on the person etc but mainly how critical is the way it's fitted to the person. (minus antenna characteristics, I already get how a better sky view helps but what if the receiver is in your bag 90 degrees to the right??) Thanks No virus found in this incoming message.
