Some programs such as LK8000 can do this. In setup you select the
primary and secondary GPS sources. If the signal is lost from the
primary, the secondary is automatically selected. It periodically
checks availability of the primary. When/if it returns, it will
automatically be selected. I don't know if SeeYouMobile has that
function.
