Contact Information ----------------------------------------------------------------------------- If you have any questions regarding this file contact SPICE support at ESAC: Marc Costa Sitja (+34) 91-8131-457 mcosta@sciops.esa.int, esa_spice@sciops.esa.int or NAIF at JPL: Boris Semenov (818) 354-8136 Boris.Semenov@jpl.nasa.gov Implementation Notes ----------------------------------------------------------------------------- This file is used by the SPICE system as follows: programs that make use of this frame kernel must "load" the kernel normally during program initialization. Loading the kernel associates the data items with their names in a data structure called the "kernel pool". The SPICELIB routine FURNSH loads a kernel into the pool as shown below: FORTRAN: (SPICELIB) CALL FURNSH ( frame_kernel_name ) C: (CSPICE) furnsh_c ( frame_kernel_name ); IDL: (ICY) cspice_furnsh, frame_kernel_name MATLAB: (MICE) cspice_furnsh ( 'frame_kernel_name' ) PYTHON: (SPICEYPY)* furnsh( frame_kernel_name ) In order for a program or routine to extract data from the pool, the SPICELIB routines GDPOOL, GIPOOL, and GCPOOL are used. See [2] for more details. This file was created and may be updated with a text editor or word processor. * SPICEPY is a non-official, community developed Python wrapper for the NAIF SPICE toolkit. Its development is managed on Github. It is available at: https://github.com/AndrewAnnex/SpiceyPy Naming Conventions ------------------------------------------------------------------------------ All names referencing values in this I-kernel start with the characters 'INS' followed by the NAIF BepiColombo MPO spacecraft ID number (-121) and then followed by a NAIF three digit code for an SIMBIO-SYS camera (HRIC = 600, STC = 610, VIHI = 620). The remainder of the name is an underscore character followed by the unique name of the data item. For example, the HRIC boresight direction in the MPO_SIMBIOSYS_HRIC frame (see [2]) is specified by: INS-121600_BORESIGHT The upper bound on the length of the name of any data item identifier is 32 characters. If the same item is included in more than one file, or if the same item appears more than once within a single file, the latest value supersedes any earlier values. Mounting Alignment ------------------------------------------------------------------------------ Refer to the latest version of the BepiColombo MPO Frames Definition Kernel (FK) [3] for the SIMBIO-SYS reference frame definitions and mounting alignment information. Description ------------------------------------------------------------------------------ From [6]: SIMBIO-SYS has been conceived to be integrated on the BepiColombo MPO pointing in the nadir direction in order to perform the remote sensing of the Mercury surface during the satellite orbits. The SIMBIO-SYS instrument architecture is based on 3 different channels composing the instrument front-end with a common main electronics and power supply. Each channel is composed of optics, detector (Focal Plane Assembly), thermal hardware (if needed), proximity electronics and electrical interface for power supply and data handling. From an electrical point of view, the Main Electronics (ME) implements, at suite level, the two main functions shared among the three channels to avoid duplication, namely: - data processing electronics function - power supply The first function, implemented by the two redundant Digital Processing Units (DPU's), is mainly devoted to data management and compression, instrument control and TC/TM handling from/to the S/C interface. The second one, implemented by the Power Unit (PU), is aimed to supply all the subsystems with the required power, providing a common set of required voltages. Science Objectives -- The SIMBIO-SYS instrument suite incorporates capabilities to perform: - global mapping with stereo imaging (spatial resolution: 50 - 110 m and vertical accuracy of 84 m at the periherm on the equator) - colour mapping of selected regions in 4 broad band filters (in the range 410-930 nm) - global mapping with spectroscopy in the spectral range 400 - 2000 nm (spectral sampling of 6.25 nm), with a spatial resolution better than 500 m - high spatial resolution (5-10 m) imaging of selected areas summing up to at least 20% of planet surface in a panchromatic filter and in 3 different broad band filters (in the range 400-900 nm) - hyperspectral imaging of selected areas in the spectral range 400 - 2000 nm (spectral sampling of 6.25 nm), with a spatial sampling down to 100 m Measurement Principle -- The above scientific objectives are achieved by the capabilities of the three channels composing the SIMBIO-SYS suite: - STC Stereo Camera - HRIC High Resolution Camera - VIHI Spectrometer Such configuration allows maximising the scientific return in each phase of the mission by the suitable share of the available resources in terms of power and data rate.
