Poul-Henning did already give the answer. However i am not very happy with the formulation
> In other words, it has nothing to do with the receiver, it's > about what you ask it to do. because a) I never saw a navigation receiver featuring a "position hold" mode b) I never saw a timing receiver featuring a "navigate forever" mode. Everything that i had in my hands had a "automatic site survey" mode after which it would return to "position hold". That's why i think the formulation that it depends on the receiver's primary purpose is not that wrong!
