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 correction by (42.980 ... An excellent account of the role played by general relativity in the design of GPS can be found in Ashby 2003. [65]
The pseudorange (from pseudo-and range) is the pseudo distance between a satellite and a navigation satellite receiver (see GNSS positioning calculation), for instance Global Positioning System (GPS) receivers.

(Regarding "in place of the TDOP component": Since the clocks on the legacy International Cospas-Sarsat Programme LEO satellites are much less accurate than GPS clocks, discarding their time measurements would actually increase the geolocation solution accuracy.) The elements of are designated as:
From January 2008 to December 2012, if you bought shares in companies when Charles H. Cotros joined the board, and sold them when he left, you would have a 94.1 percent return on your investment, compared to a -2.8 percent return from the S&P 500.
