ORBIT COMPUTATION:                                                            
    Double difference phase observations of GLONASS and GPS satellites are    
    processed in ionosphere free linear combination.                          
                                                                              
    IGS orbits and Earth rotation parameters are fixed.                       
                                                                              
    Six initial conditions and nine radiation pressure parameters per         
    satellite are determined for GLONASS satellites.                          
                                                                              
    The middle day of a 3-day-arc is used for the daily orbit results.        
                                                                              
    The daily orbit files include GPS satellite clock values from IGS         
    estimates and broadcasted values for GLONASS satellite clocks.            
                                                                              
    The coordinates of the following stations are contrained to ITRF-97:      
    GODZ IRKZ OS0G YARR ZIMZ WTZZ.                                            
                                                                              
GLONASS/GPS TIME OFFSET:                                                      
    Code observations of combined GLONASS/GPS receivers are used to           
    determine the GLONASS/GPS time offset.                                    
                                                                              
    This offset includes the modulo 1 sec system time scale difference of     
    GLONASS and GPS and an additional offset between the receiver's           
    'GPS clock' and 'GLONASS clock'. The additional offset is receiver        
    dependent.                                                                
                                                                              
TRANSFORMATION PARAMETERS BETWEEN ITRF AND PZ90:                              
    The transformation parameters are derived from GLONASS precise orbits     
    (given in ITRF) and GLONASS broadcast orbits (given in PZ90).
