Spacecraft position and speed

Here is some data obtained by interpolating the original data files for the following coverage windows (times are given in TDB):
S/C    : START: , END: 
Mercury: START: , END: 
Venus  : START: , END: 
Earth  : START: , END:
The graph shows the location of the bodies as seen from the ecliptic north pole in the heliocentric mean ecliptic and equinox of J2000 reference frame.

Simulation speed:
Center: Zoom


Bodies Distance Speed
D [km] err [m] V [km/s] err [mm/s]
S/C - Sun
S/C - Venus
S/C - Earth
Mercury - Sun
Venus - Sun
Earth - Sun

The table shows the distance between the center of the bodies and the speed.
The columns "err" represent the maximum interpolation error for that TDB time (most of the time, the interpolation error is much smaller than the maximum error).

The interpolation error is calculated as: \(err=\sqrt{(x_{1} - x_{2})^2 + (y_{1} - y_{2})^2 + (z_{1} - z_{2})^2}\), where the components with subscript 1 are interpolated and those with subscript 2 are the components obtained from the original data files.
