Solar Radiation Pressure Coefficients for GLONASS Satellites
The coefficients of the solar radiation pressure model are plotted
for several days of the campaign. It is remarkable that:
The X term is the direct solar radiation pressure force. The value
is about 150 nanoNewton for most of the satellites and about 80-90
nanoNewton for gv-64.
The Y term is the well known y bias with values in the interval
-0.5 to +0.5 nanoNewton for most of the satellites. There are some
regular variations on some satellites that could be investigated.
The Z is decomposed in constant, sine and cosine terms. The constant
one with values in the interval -5 to +5 nanoNewton. Problematic
satellites like gv-66 and gv-75 show large variation in this term.
The cosine term is in the interval -20 to +20 nanoNewtons and the
sine term around -3 nanoNewtons depending on the satellite.
