Roemer is accredited as the first to measure the velocity of light using the eclipse of Io but the eclipse of Io can only be viewed from Jupiter. Bradley's stellar aberration is used to calculate the velocity of light but Bradley's measurements are within the measurement uncertainty using a pendulum clock that is used to determine the displacement of Bradley's star during a solar eclipse. Fizeau (1849) measures the velocity of light using a rotating cogwheel but to measure the velocity of light requires the time a single light pulse propagates a specific distance yet Fizeau's cogwheel is producing a series of light pulses. Foucault (1850) replaced Fizeau's cogwheel with rotating mirrors which also forms a series of light pulses. Weber-Kohlrausch (1856) calculate the velocity of light using the units of a discharging capacitor but the electrons of a discharging capacitor are propagating at the velocity of 106 m/s. Michelson (1926) attempts to calculate the velocity of light using an interferometer and wave equation (λf = c) but Michelson's interference fringes are formed by an ether and the wave equation is also based on light waves formed by the motion of an ether that does not physically exist. An oscilloscope is used to determine the velocity of light but the wave pattern formed by the oscilloscope is formed by electrons that are propagating at the velocity of 106 m/s yet light propagates at the velocity of 108 m/s. Furthermore, GPS (Global Positioning System) is used to justify the measurement of the velocity of light but the GPS is produced by the intensity differences of the satellites' radio signals not by the velocity of the radio signals since the electrons of the GPS system cannot measure the time difference of radio waves propagating at the velocity of light. The velocity of light is unknown.
The velocity of light, impossible to be measured with enough accuracy, was settled axiomatically as 299,792,458 m/sec by the
international institution BIMP by 1986 (and NIST agree with this axiomatic value of c). Read something about it here:
Latest measurements of c, h and G "universal" constanst. Some doubts.

So, the speed of c has been axiomatically defined by a bunch of technical bureaucrats from several countries.
Problem solved. Next!
