In the context of GPS the most prominent correction introduced by general relativity is gravitational time dilation: the clocks located deeper in the gravitational potential well (i.e. closer to the attracting body) tick slower. Satellite clocks are slowed by their orbital speed but sped up by their distance out of the Earth's gravitational well.
The GPS implements two major corrections to its time signals for relativistic effects: one for relative velocity of satellite and receiver, using the special theory of relativity, and one for the difference in gravitational potential between satellite and receiver, using general relativity.
The United States' Global Positioning System (GPS) consists of up to 32 medium Earth orbit satellites in six different orbital planes. The exact number of satellites varies as older satellites are retired and replaced. Operational since 1978 and globally available since 1994, GPS is the world's most utilized satellite navigation system.

The effect of gravitational frequency shift on the GPS system due to general relativity is that a clock closer to a massive object will be slower than a clock farther away. Applied to the GPS system, the receivers are much closer to Earth than the satellites, causing the GPS clocks to be faster by a factor of 5×10^(-10), or about 45.9 μs/day.

It is said as much in the next sentence, but so indirect, that an average reader is likely, I think, to read this passage as "without relativity adjustments GPS would skrew up by 10km a day (so the adjustments are made by GPS)". It seems to me quite misleading, and I think it can be phrased without casting such impressions.
