Detailed Description

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
Determine SPICE kernels defined in an ISIS file.
Definition Kernels.h:94

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.

◆ computeSolarLongitude()

◆ createCache()

void Isis::Spice::createCache ( iTime startTime,
iTime endTime,
const int size,
double tol )
virtual

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().

Parameters
startTimeStarting ephemeris time to cache
endTimeEnding ephemeris time to cache
sizeSize of the cache.
tolTolerance.
Exceptions
Isis::IException::Programmer- "Argument cacheSize must be greater than zero"
Isis::IException::Programmer- "Argument startTime must be less than or equal to endTime"

◆ getClockTime()

iTime Isis::Spice::getClockTime ( QString clockValue,

virtual

This converts the spacecraft clock ticks value (clockValue) to an iTime.

If the clock ticks value is provided directly, rather than the spacecraft clock string, set clockTicks=true.

Use this when possible because naif calls (such as scs2e_c) cannot be called when not using naif.

Member Data Documentation

◆ m_BJ

SpiceDouble Isis::Spice::m_BJ[3][3]
protected

This contains the transformation matrix from J2000 (J) to Body fixed (B).

Recall that the transpose of this matrix JB will convert from body-fixed to J2000. It is left in protected space so that conversions between double and SpiceDouble do not have to occur in inheriting classes.

◆ m_et

◆ m_solarLongitude

Longitude* Isis::Spice::m_solarLongitude
protected

Body rotation solar longitude value.

Referenced by computeSolarLongitude(), solarLongitude(), and ~Spice().

◆ m_target

Target* Isis::Spice::m_target
protected

◆ m_uB

SpiceDouble Isis::Spice::m_uB[3]
protected

This contains the sun position (u) in the bodyfixed reference frame (B).

It is left protected so that conversions between double and SpiceDouble do not have to occur in inheriting classes. Units are km
