 
 
MRO TLM-Based Spacecraft Orientation CK File
============================================================================
 
 
Orientation Data in the File
--------------------------------------------------------
 
     This file contains actual orientation and angular velocity data for the
     Mars Reconnaissance Orbiter (MRO) spacecraft frame,
     'MRO_SPACECRAFT', relative to the Mars Mean Equator and Equinox of
     Date, 'MRO_MME_OF_DATE', frame. The NAIF ID code for the
     'MRO_SPACECRAFT' frame is -74000.
 
 
Status
--------------------------------------------------------
 
     This file is a regular operational reconstructed C-Kernel file created
     by NAIF. It contains quaternions and angular rates extracted from
     engineering telemetry downlinked from the spacecraft.
 
 
Pedigree
--------------------------------------------------------
 
     This CK file was generated by an automated process. This process
     extracts spacecraft orientation quaternions and angular rates
     from ACS telemetry and writes them to a CK file using MSOPCK program.
     While quaternions and angular rates were "paired" in telemetry, the rates
     generated on-board by IMU were not for the exact times, for which
     quaternions were computed by the Kalman filter. Thus the rates
     stored in this CK are shifted forward in time by a small unknown
     offest relative to quaternions.
 
 
Approximate Time Coverage
--------------------------------------------------------
 
     This file is a type 3 CK file (segment) which provides linear
     interpolation between orientation data points extracted from
     telemetry. Such interpolation is not applied to the whole coverage of
     a segment but only inside intervals where enough orientation
     telemetry data was available and orientation data points were close to
     each other in time for such interpolation to make sense.
 
     A table containing the complete list of valid interpolation intervals
     in each segment of the the file is provided at the end of these comments.
 
     The start time and stop time of the total coverage for every segment
     in the file are given in the header of the intervals table for that
     segment.
 
 
Usage Note
--------------------------------------------------------
 
     In order to use this file an MRO SCLK file, containing
     coefficients mapping MRO on-board time to ET, standard LSK file,
     providing UTC to ET mapping, and MRO Frames kernel, providing
     definition of the frame with respect to which the attitude data is
     given, must be loaded into a user program.
