As I said, this time the design notes were extensive since I wanted this emulator to be specifically designed for embedded systems, so only 48k emulation, optional framebuffer rendering, very little additional memory used (no big lookup tables for ULA/Z80 access contention), ROM not copied in the RAM to avoid using additional 16k of memory, but just referenced during the initialization (so we have just a copy in the executable), and so forth.
One reason for routinely launching GPS satellites is simply "constellation replenishment," said Col. Andrew Menschner, deputy commander of the Space Force's Space Systems Command. Old satellites degrade and die, and new ones need to go up and replace them. At least 24 GPS satellites are needed for global coverage, and having additional satellites in the fleet can improve navigation precision. Today, there are 31 GPS satellites in operational service, flying more than 12,000 miles (20,000 kilometers) above the Earth.
