M01 Spacecraft Orientation CK File for Extended, 2006-01 ... 2006-03 =========================================================================== Created by Boris Semenov, NAIF/JPL, Wed May 10 09:59:53 PDT 2006 Orientation Data in the File -------------------------------------------------------- This file contains orientation and angular velocity data for the Mars-01 Odyssey (M01) spacecraft frame, 'M01_SPACECRAFT', relative to the 'MARSIAU' inertial frame. The NAIF ID code for the 'M01_SPACECRAFT' frame is -53000. Status -------------------------------------------------------- This file was created by NAIF for archiving with the Planetary Data System (PDS) from daily CK files produced by NAIF Team, 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 spacecraft frame orientation relative to the 'MARSIAU' inertial frame. The orientation was computed, converted to quaternions and filtered on-board; filtered quaternions were transmitted to the Earth in the channelized telemetry. On the ground quaternions were extracted from telemetry and written to daily CK files using the MSOPCK program. The individual daily files were merged together to provide complete coverage on a mission/monthly phase basis. 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 Extended phase of the mission: Coverage Begin UTC Coverage End UTC ------------------------ ------------------------ 2006-JAN-01 00:00:04.076 2006-MAR-31 23:59:56.804 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 quaternion time spacing in the telemetry stream varied from a fraction of a second to 3-4 seconds between adjacent data points. Considering that the s/c was nominally nadir pointed for all science data collection periods and three axis stabilized from most other operation regimes, the duration of the longest interval over which the data may be interpolated was set to 60 seconds. For all requests for data falling between two adjacent data points separated by more than 60 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 is provided at the end of these comments. Angular Rate Data Note -------------------------------------------------------- Data records in this file do not contain actual angular rates computed on-board because the angular rates were not available in all telemetry packets containing quaternions. Instead, the angular rates stored in the file were "manufactured" by MSOPCK program using an assumption that the spacecraft was rotating at a constant rate between each two orientations specified by neighbor quaternions. 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. Related Kernels -------------------------------------------------------- This file was created using the following LSK and SCLK files: naif0008.tls ORB1_SCLKSCET.00128.tsc Contacts -------------------------------------------------------- If you have any questions regarding this data contact NAIF at JPL: Charles H.
