A field's local data is a ladder — value, slope, curvature. A clock at rest reads one rung.
Sets the clock rate: φ/c², the field's share of the energy budget. This page's whole signal.
Needs one power of speed to couple. It holds the satellite in orbit — but on a circular orbit it is perpendicular to the motion, so this reading is exactly zero.
Needs two powers of speed. Here that puts it near one part in 10²⁰ — real, but ten billion times beneath the signal.
GPS Satellite Reference
GPS satellites orbit at ~20,200 km altitude and gain approximately +45 μs per day relative to Earth surface clocks.
