Hi Mike,
NASA scientists seem to think that satellite motion is consistent with
general relativity, not Newtonian mechanics...

041022005256&e=4
...and that they don't need to use a rotating reference system for satellite
navigation and tracking:
The Satellite Situation Center Web (SSCWeb) service has been developed
.... to support a range of NASA science programs and to fulfill key
international NASA responsibilities including those of NSSDC and the World
Data Center-A for Rockets and Satellites.
The software and associated database of SSCWeb together form a system to
cast geocentric spacecraft location information into a framework of
(empirical) geophysical regions and mappings of spacecraft locations along
lines of the Earth's magnetic field.
This service enables computation of a set of the main geomagnetic field
model parameters and transformation from the GEOcentric spherical
(geographic) coordinates to the Corrected GeoMagnetic (CGM) coordinates and
vice versa. .....
The input parameter (sic) are:
a.. Geocentric or Corrected GeoMagnetic Latitude and Longitude
b.. Altitude above the 1-Re (6371.2 km) surface: 40,000 km limit
c.. Year for Definitive/International Geomagnetic Reference Field
(DGRF/IGRF) models from 1945 to 2005
The GPS system uses an Earth-Centered, Earth Fixed (ECEF) frame of reference
and is not bashful about defining it as geostatic:
http://www.commlinx.com.au/Datum%20Transformation%20Description.html
But the Geocentric input parameters used by NASA above are free of external
references to the Sun or the stars, using a surface point to fix the
longitude (Greenwich). So the reference system is correctly termed
geostatic, not just geocentric.
Have you notified NASA of their errors?
Robert

Hi Jack,
The satellites orbiting the earth now (including the moon) are
consistent with Newtonian mechanics and the earth rotating once every
sidereal day to a very high degree of accuracy. So if you believe the
earth does not rotate you have two choices:
1. Newtonian mechanics is wrong
2. The satalites aren't there (including the moon)
Regards,
Mike.
