A2.2.14.2          Engineering Formats                                        
                                                                              
    There are 5 GLL engineering formats, four of which are on the  S/C at     
    any one time. These formats are: anomaly, launch  phase 1, launch         
    phase 2, cruise/encounter/orbital operations, and  maneuver/all spin.     
    Each of these formats consists of a fixed area containing measurements    
    common to all formats, and a variable area, containing packets of         
    measurements unique to the specific format.  Figure A2.2.12 provides      
    an overview of the engineering commutator structure, showing the fixed    
    and variable areas.  The paragraphs that follow indicate the assignment   
    of measurements to specific commutator positions within the fixed and     
    variable areas.                                                           
                                                                              
A2.2.14.2.1        Fixed Area Measurement Assignments                         
                                                                              
    Figures A2.2.13 through A2.2.19 indicate the commutator                   
    positions assigned to measurements in the fixed area.
