M01 Solar Array Orientation CK File for Mapping, 2003-07 ... 2003-09 =========================================================================== Created by Boris Semenov, NAIF/JPL, Sun Nov 9 09:46:38 PST 2003 Orientation Data in the File -------------------------------------------------------- This file contains orientation and angular rate data for the Mars'01 Odyssey (M01) Solar Array (SA) Inner and Outer gimbal frames. The orientation of the 'M01_SA_INNER_GIMBAL' is given with respect to the 'M01_SPACECRAFT' frame; orientation of the 'M01_SA_OUTER_GIMBAL' is given with respect to the 'M01_SA_INNER_GIMBAL' frame. The NAIF IDs for the 'M01_SA_INNER_GIMBAL' and 'M01_SA_OUTER_GIMBAL' frames are -53311 and -53312. Status -------------------------------------------------------- This file was created by NAIF for archiving with the Planetary Data System (PDS) from daily CK files produced by NAIF, JPL. Pedigree -------------------------------------------------------- The original CK files used to create this file were officially delivered to the M01 project by the NAIF Team. These files contained the inner gimbal frame orientation with respect to the spacecraft frame and the outer gimbal frame orientation with respect to the inner gimbal frame. The orientation was computed on the ground from the solar array gimbal angles extracted from the channelized telemetry sent down by the spacecraft. The individual daily CK files were merged together to provide coverage for a complete or a portion of a particular phase of the mission. A table containing the complete list of original CK files from which data were included in this file is provided at the end of these comments. Approximate Time Coverage -------------------------------------------------------- This file covers the following interval of the Mapping phase of the mission: Coverage Begin UTC Coverage End UTC ------------------------ ------------------------ 2003-JUL-01 00:01:06.235 2003-SEP-30 23:59:40.255 This file is a type 3 CK file which provides linear interpolation between orientation data points extracted from telemetry. Such interpolation is not applied to the whole coverage of the file 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. The nominal gimbal angle time spacing in the telemetry stream varied from one to a few seconds between adjacent data points. Considering that the array gimbal cannot rotate very fast and that the highest accuracy of the SA orientation knowledge is unlikely to be needed in any application, the duration of the longest interval over which the data may be interpolated was set to 300 seconds. For all requests for data falling between two adjacent data points separated by more than 300 seconds the SPICELIB CK readers will return a logical flag stating "POINTING NOT FOUND". A table containing the complete list of valid interpolation intervals in the file segments is provided at the end of these comments. Angular Rate Data Note -------------------------------------------------------- Since M01 s/c engineering telemetry did not contain angular rate data for the gimbal, the angular rates stored in this file were computed from the orientation information. The angular rate for each orientation point was computed as average of two rates -- constant angular rate that would rotate from previous point to that point and constant angular rate that would rotate from that point to the next point. Because angular rates stored in two adjacent points in most cases are not the same, and CK readers linearly interpolate between them, the output angular rates in general will never be constant between any two adjacent data points stored in the file. Usage Note -------------------------------------------------------- In order to use this file an M01 SCLK file containing coefficients mapping M01 on-board time to ET must be loaded into a user's program. Loading an M01 Frames Kernel (FK) containing information that SPICE software need to combine gimbal orientations together will allow a user to get the combined orientation through the high level SPICE Toolkit interfaces.
