Actually, GPS knows about this and takes advantage of it. It is the only consumer relativity application I know of.
The GPS SV's are going about 3900 m/s which is a sufficient percentage of the speed of light for relativity to come into play. If relativity weren't taken into account and Einstein obeyed, you'd be off by ~100 meters.
The correction could be done in the receiver or the signal could be biased in the SV. Following the Principle of Alice's Restaurant:
One Big Pile Is Better Than Two Little Piles
Factoring this correction into the SV,
the onboard clocks use a frequency of 10.22999999543 MHz and your GPS receiver uses 10.23 MHz. This simplifies the GPS receiver software immensely.
GPS was designed during the 1970's by some really smart forward thinking guys.
DVDs took awhile.
LANs took awhile. Remember the year of the LAN?
PDAs took awhile, until Palm then they took off.
Mozilla is taking awhile, but is mighty fine.
If I ever do the nasty with Britney,
I'll take awhile.
Some things just take awhile. I have a Replay
and I can't stand watching TV at a friends house.
The value proposition is just too strong.
Sure installation is a pain, but instant replay,
commercial skipping, middle of the night or day
recording, search, I just couldn't go back.
