Detailed Description

The EphemerisTable class is an Alma table.


Role


Generated from model's revision "-1", branch ""

Attributes of Ephemeris

Name

Type

Expected shape

Comment

Key

timeInterval

ArrayTimeInterval

 

 interval of time during which the data are relevant.

ephemerisId

int

 

 identifies a collection of rows in the table.

Value
(Mandatory)

observerLocation

vector<double >

3

 a triple of double precision values defining the observer location. This triple contains in that order the longitude, the latitude and the altitude of the observer :

  • the longitude is expressed in radian. An east (resp. west) longitude is denoted as a positive (resp. negative) quantity.
  • the latitude is expressed in radian. A north (resp. south) latitude is denoted as a positive (resp. negative) quantity.
  • the altitude is expressed in meter. It's the altitude above the reference ellipsoid.

A triple with all its elements equal to 0.0 will mean that a geocentric coordinate system is in use instead of a topocentric one.

equinoxEquator

double

 

 epoch at which equator and equinox were calculated for ephemeris. Expresses a year as a decimal value (J2000 would be represented as 2000.0).

numPolyDir

int

 

 the number of coefficients of the polynomial stored in phaseDir. It has to be $ \ge 1 $.

dir

vector<vector<double > >

numPolyDir, 2

 the ephemeris direction expressed in radian. The nominal entry in the phaseDir, delayDir, or ReferenceDir in the Field table serves as additional offset to the direction described by "dir". The actual direction is obtained by composition, e.g. actual phase direction = [phasDir value from Field table] + [dir].

The direction described by dir is the result of the sum

\[ dir_{0,i} + dir_{1,i}*dt + dir_{2,i}*dt^2 + ... + dir_{numPolyDir-1,i}*dt^{numPolyDir-1}, \forall i \in \{0,1\} \]

where

\[ dt = t - timeOrigin \]

numPolyDist

int

 

 the number of coefficients of the polynomial stored in distance. It has to be $ \ge 1 $.

distance

vector<double >

numPolyDist

 the coefficiens of the polynomial used to calculate the distance, expressed in meter, to the object from the position of the antenna along the given direction. This distance is the result of the sum :

\[ distance_0 + distance_1*dt + distance_2*dt^2 + ... + distance_{numPolyDist-1}*dt^{numPolyDist-1} \]

where

\[ dt = t - timeOrigin \]

.

timeOrigin

ArrayTime

 

 the time origin used in the evaluation of the polynomial expressions.

origin

string

 

 the origin of the ephemeris information.

Value
(Optional)

numPolyRadVel

int

 

  the number of coefficients of the polynomial stored in radVel . It has to be $ \ge 1 $.

radVel

vector<double >

numPolyRadVel

  the coefficients of a polynomial expressing a radial velocity as a function of the time expressed in m/s. The time origin used to tabulate the polynomial is stored in timeOrigin.

Constructor & Destructor Documentation

virtual asdm::EphemerisTable::~EphemerisTable (  )  [virtual]
asdm::EphemerisTable::EphemerisTable ( ASDM container  )  [private]
