LADEE FRAMES Kernels ------------------------------------------------------------------------ Version 1.1; May 20, 2021 General Information About SPICE Frames Kernels ============================================== In the SPICE system, FRAMES kernel contains a set of information required to define various frames used in a particular mission, sources of orientation and origin location information for these frames and inter-connections between these frames and other frames supported within the SPICE system. The frame definitions information contained in the file can be utilized in conjunction with other data using the SPICE Toolkit APIs, calls to which can be integrated into user application programs. The SPICE system toolkit for a number of languages and computer platforms can be obtained from the NAIF web site (http://naif.jpl.nasa.gov/). Refer to the ``frames.req'' document provided with the toolkit to get more information about definition and usage of the frames within the SPICE system. LADEE Frames Kernels Contained in This Archive ============================================== The following Frames Kernel files are included in this archive: ladee_frames_2021140_v01.tf LADEE Mission FK file containing the ladee_frames_2014159_v01.tf complete set of frame definitions for the spacecraft and science instruments. moon_080317.tf Lunar Reference Frames FK file specifying lunar body-fixed reference frames -- ``Mean Earth'' (ME) and ``Principal Axis'' (PA) frames -- associated with high-accuracy lunar orientation data provided by the JPL Solar System Dynamics Group's planetary ephemerides DE421. moon_assoc_me.tf Lunar Reference Frame Associations moon_assoc_pa.tf FK files are used to associate either ME or PA frame with the Moon. Only one of these kernels needs to be loaded at a time in order for some older SPICE APIs to perform computations in that frame. Neither of these kernels is needed for the latest SPICE APIs. If more than one FK of a particular kind is present in this directory, the FK with the latest release date and version supersedes all FKs with earlier release dates and versions. Kernel File Details =================== The most detailed description of the data in an FK file is provided in metadata included inside the description area of the file. This information can be viewed using any text editor program.
