You do have to be aware that at different times of the day, the
signal will vary. IIRC about 2 in the afternoon is particularly bad
as the arrangement of the satellite constellation means that over the
UK they tend to be nearer the horizon. A human body will also act as
a good shield the the GPS signal. If you are out walking, ideally
you wand one that can be fitted to your hat :-)
