Geodetic Reference System (called BEST CURRENT 2008) identifies four defining parameters. These are the semi-major axis , the flattening factor of the Earth, and the geocentric gravitational constant.....etc. as specified below.
A = 6378136.30 M
1/F = 298.2577550
GM= 0.3986004415E+15
REF.GRAVITY AT EQUATOR = 978032.7431 MGAL
POTENTIAL AT REF.ELL. = 62636858.3963 M**2/SEC**2
I'm looking for the other parameters such as (Physical Constants - Geometric Constants - Physical Constants) for Geodetic Reference System 1984 (BEST CURRENT 2008) and Reference of this parameters
Please, see:

Good luck!
Dear Dr. Vagner
Thanks for adding your answer
the GRAVSOFT package (C.C.Tscherning)
used two Geodetic Reference System in Python Interface “GEOCOL”
1- REFERENCE SYSTEM: GRS1980.
A = 6378137.00 M
1/F = 298.2572204
GM= 0.3986005000E+15
REF.GRAVITY AT EQUATOR = 978032.6772 MGAL
POTENTIAL AT REF.ELL. = 62636860.8504 M**2/SEC**2
2- REFERENCE SYSTEM: BEST CURRENT 2008.
A = 6378136.30 M
1/F = 298.2577550
GM= 0.3986004415E+15
REF.GRAVITY AT EQUATOR = 978032.7431 MGAL
POTENTIAL AT REF.ELL. = 62636858.3963 M**2/SEC**2
I'm looking for More information about this Reference System
Very Thank
Abdel Rahim
