People forget that GPS came along strong in 2003 and later. It was in use about mid 1990’s, though didn’t catch on till early 2000’s for most. In the early 1990’s aircraft used LORAN for navigation based on triangulation of tower signals.
Younger adults today don’t realize that in 1990 a cell phone was not an item for most. By mid 1990’s bag phones were common and the iPhone was just 13 years ago. Before that we had Nokia, Motorola, LG and more. Who remembers Nextel today... let alone satellite phones.
my how far we’ve come.
