GPS and NASA are to Satanism as Protestantism and Catholicism are to Christianity - they have minor differences in dogma but underlying arise from the same faith, and they help eachother out in their endeavours.
GPS "signals" are broadcast from a continuously fuel-replenishing fleet of high-altitude, ex-cold war fighters and bombers. The 50th Space Wing, NASA's military predecessor, neglected to decommission these planes, using them instead to conduct one of the greatest hoaxes in history. Their coat of arms is a terrifying skeletal, goat-hoofed demon taking wing across a desolate sky.
However, as Protestantism to Catholicism, NASA's Satanic ventures and direction have expanded beyond original Satanic dogmas held by the 50th Space Wing. Now, as shown by NASA's new logo, which contains a chevron (one fifth of a complete pentagram) they are more focussed on being one of the Satanic Order of Five Space Agencies - NASA, POCKOCMOC, CNSA, IRNSS and JAXA, whose combined logos create a recursive pentagram, one chevron of which is itself a pentagram. This is taken to symbolise the eternal and unending nature of their deception, and to glorify their deity, Satan.
So now, the 50th Space Wing is merely one of NASA's many denominational schisms. I do not know if NASA has invented the microwave, but I would not put it past them to falsely market a supposedly new product for exorbitant cost, which in reality is no more effective than a camping stove in a cardboard box. The shoddy workmanship visible in most microwaves certainly does remind me of the mock-up space shuttle (a deception), whose outside was made out of pottery tiles and glue, and would routinely fall off at the slightest provocation (being moved, sitting still, riding on the back of a Boeing 747, deceiving public eyes).
