I see.  It is the fault of civil engineering, who gave us Aetherist, who in turn revived the obsolete luminiferous aether.  I await the new ichor.
Yes, relativity made a minor contribution to GPS, which has had a large impact on civil engineering (properly defined).
Also, Einstein's theory of stimulated emission (due to his interest in thermodynamics) led to the invention of the laser, which also aided civil engineering, even though he was not happy with quantum physics.

The twentieth century was something that happened to other people.

Relativity affects almost everything, including GPS. But Einsteinian Relativity is rubbish, there is no such thing as spacetime. The relativity that affects GPS is aetheric relativity, which is due to the aetherwind. However, there are different versions of aetheric relativity, my own is best. Aetheric relativity affects length contraction, & length contraction affects the ticking of clocks (all clocks).
TimFox:
By the way, Heaviside is one of my favorites from that time in history. 
1.  There was a real problem.  Transatlantic telegraph cables were absurdly slow.
2.  "Everybody knew" that shunt capacitance and series inductance would slow down a signal.
3.  Heaviside demonstrated that adding a proper combination of inductances along the cable (with its inherent capacitances) would improve things greatly.
4.  While British authorities resisted this idea, Americans (working for AT&T) reduced Heaviside's loading coils to practice for trunk lines and the rest is history.
5.  Most modern installations use coaxial transmission lines instead of lumped-constant designs.

Heaviside was a genius. And i don’t understand his solution for cables. But Heaviside failed to see the failures of his E×H slab (slab koz there is no rolling E to H to E bullshit going on) of energy current that propagated in the air outside wires, ie tween wires (ie which accords with the Poynting Vector explanation for electricity beloved by Veritasium). Heaviside failed to see that….
Electricity can propagate along a single wire.
Insulation on a wire slows electricity (which his E×H can't explain).

Heaviside would be happy with my new (electon) electricity. It solves the insulation paradox, whilst retaining his precious E×H. And Veritasium would be happy with my new (electon) electricity, it duznt explicitly deny his Poynting Vector contribution to electricity (except that it duz).
TimFox:
Heaviside's solution for cables led further to the development of continuous transmission lines.
These are rather important things to understand in connection with speed of electrical information transmission.
