Obtain SPICE information for a spacecraft.
This class initializes standard NAIF SPICE kernels in order to allow queries of a spacecraft's position and attitude at a given time. It also allows for access to the position of the sun and transformation matrices from J2000 to a body-fixed reference frame for a given target (e.g., Mars). The constructor for this class expects a PVL object with the following minimum information:
Group = Instrument
TargetName = Mars
EndGroup
Group = Kernels
NaifFrameCode = -94030
LeapSecond = naif0007.tls
TargetAttitudeShape = pck00006.tpc
TargetPosition = de405.bsp
InstrumentPointing = (mgs_sc_ab1.bc,
Instrument = moc13.ti
SpacecraftClock = MGS_SCLKSCET.00045.tsc
InstrumentPosition = mgs_ab1.bsp
InstrumentAddendum = mocAddendum.ti
EndGroup
This group is typically found in the image labels after it has been run through the program "spiceinit" It is recommended you read NAIF documentation to obtain a better understanding about the various types of SPICE kernels. The NAIF toolkit accesses information from kernels on a last-in-first-out (LIFO) basis. This means that the creation of a second object can cause problems with the first object. To alleviate this problem we have supplied the CreateCache method which should be invoked immediately after the object is constructed. This caches information (spacecraft position, pointing, etc) internally in the object and unloads all NAIF kernels.
enum Isis::Spice::SpiceValueType [protected] |
| Isis::Spice::Spice | ( | Cube & | cube | ) |
Constructs a Spice object and loads SPICE kernels using information from the label object.
The constructor expects an Instrument and Kernels group to be in the labels.

| iTime Isis::Spice::cacheEndTime | ( | ) | const |
Accessor method for the cache end time.
| iTime Isis::Spice::cacheStartTime | ( | ) | const |
Accessor method for the cache start time.
This method creates an internal cache of spacecraft and sun positions over a specified time range.
The SPICE kernels are then immediately unloaded. This allows multiple instances of the Spice object to be created as the NAIF toolkit can clash if multiple sets of SPICE kernels are loaded. Note that the cache size is specified as an argument. Therefore, times requested via setTime() which are not directly loaded in the cache will be interpolated. If the instrument position is not cached and cacheSize is greater than 3, the tolerance is passed to the SpicePosition Memcache2HermiteCache() method.
Note: Before this method is called, the private variables m_cacheSize, m_startTime and m_endTime must be set. This is done in the Camera classes using the methods SetCacheSize() and SetStartEndEphemerisTime().
| startTime | Starting ephemeris time to cache | |
| endTime | Ending ephemeris time to cache | |
| size | Size of the cache. | |
| tol | Tolerance. |
