$$ GPS PRE & RE-set Equated.
WHERE radius rVLO is CENTRAL mass SURFACE radius r3 EQUiVALENT:

v1^2 (3873)^2 (R*g1) | GPS ambient density vVLO^2 |
-- -- = -- -- -- = -- --- = |(-- -- -- - -- -- -- ) + (------)|
2*c^2 2*c^2 2*c^2 | VLO ambient density 2*c^2 |

| 2*(nGPS - 1)*R*c^2 2*((nVLO - 1)*rVLO*c^2 2*c^2 |.

WHERE, for nGPS & nVLO @ R & rVLO, factor 2*c^2 CANCELLs OUT.!!
SO this GUESS iSS RATiO of 8.333E-11, which ad-hoc-ly "works"..

|| out to 7.2 microseconds out of 86400 seconds ([EARth] day).

|| GPS satellites are in circular orbits at 20200 km altitude,
|| or about 26580 km from the center of earth. The orbital
|| speed is given by -=-

GiVEN: G*M1*m1 / R^2 = (n - 1)*m1*v1^2 / R.
WHE
v1^2 = G*M1 / (n - 1)*R = (6.673*10^-11)*(5.974*10^24) / 2.658*10^7

| 2*(GPS ambient density)*c^2 | |2*dGPS*c^2 |
= |(-- -- -- -- --- -- -- -- -- ) + vVLO^2| = |-- - -- -- + vVLO^2|
| vVLO ambient density | | dVLO |

| 2*G*M1 2*G*M1 |
= |(-- -- --- --) - (-- -- --- -- --) + (vVLO^2)| = R*g1
| (nGPS - 1)*R (nVLO - 1)*rVLO |

|4*(pi)^2*R^2| |4*(pi)^2*R*lbob| |R*vbob^2|
= |-- --- -- --| = |-- -- --- -- --| = |-- -- --| = vGPS^2 = v1^2.
| t1^2 | | tbob^2 | | lbob |

THEN: v1 = 3873 - meter / sec;

NOTE: v1^2 / 2*c^2 = (3873^2 / 2*c^2) = 8.333*10^-11.
CLEARLY: The "EARth" clock OUGHT BE in a Very Low Orbit (a VLO)
for the arithmetic to *REALLY* "work out" ..as per the equation.
[ The FACT that the EARth clock is sitting *ON* EARth and NOT in
a VLO (so-as the arithmetic works) is REASON for DAiLY reSETs. ]
RATiO, density dGPS / dVLO = 4.4*10^-10 = GPS ..PRE-set FACTOR.!!
RATiO, density dGPS / dVLO = 0.000038 / 86400 = PRE-set FACTOR.!!

All NATURE abhors an *EMPTY* space; Especially, withOUT errorbars.!!
GUESS iSS "iN-transIT" light is a propagating SPACE medium COMiNG.!!

RESTmass = iNTRiNSiC energy eM / c^2 = (mol part)*K*Volt*meter / c^4.
Note, iNTRiNSiC REST mass = eM / c^2 = (mol part)*K*Volt*meter / c^4.
Note, iNTRiNSiC REST mass = eM / c^2 = EQUiVALENT iNTRiNSiC REST mass.
REST mass eM = E - eG = eG - eV = mass*c^2 = an intrinsic REST energy.

nA*{mph}*ls*c^2 m1*v1^2

rA 2

= m1*c^2 + ( pL*c ) + ( pA*fA )
= m1*c^2 + ( h*fL ) + ( nA*hbar*fA )
= m1*c^2 + ( pL*c ) + ( nA*hbar*fA )
= m1*c^2 + ( h*fL ) + ( pA*fA )
= eM + ( LaGrangian, L ) + eV
= eM + L + eV
= eM + eK
= eG + eK - eV
= eG + L.
Note:
EiTHER, energy + eV, OR energy - (m1*v1^2 / 2) ..NOT BOTH, AT ONCE.
[ This means that in any calculation you SWiTCH one to the OTHER. ]

- eV = + (m1*v1^2 / 2) = (E - eK - eG) = (L - eK) = (- E + L + eM).
Where-as:
+ eV = - (m1*v1^2 / 2) = (E - eM - L) = (eK - L) = (- E + eK + eG).

[ BOTH + eV and - (m1*v1^2 / 2) are CHARGEs, but DiFFERENT SiGNs. ]
[ BECAUSE + eV and - (m1*v1^2 / 2) are BOTH, Volt*Ampere*seconds. ]

$ ARiTHMETiCALLY speaking:
CLEARLY the BiGGEST DiFFERENCE, between - eV & + eV, is TWO (2) eV.
[ This is because ELECTRONs of mass leave electron HOLEs of mass. ]
[ There is NO OTHER WAY, to account for ELECTRON HOLEs phenomena. ]
[ The GUESS iSS test ELECTRON HOLE is a CAViTY of CHARGE of mass. ]
