This continuous coordinate time is equivalent to the relativistic proper time of a clock at rest in a reference frame co-moving with the solar system barycenter but outside the system's gravity well. It is the independent variable in the solar system relativistic equations of motion. TDB runs at a uniform rate of one SI second per second and is independent of irregularities in Earth's rotation. CALENDAR SYSTEM Mixed calendar mode was active such that calendar dates after AD 1582-Oct-15 (if any) are in the modern Gregorian system. Dates prior to 1582-Oct-5 (if any) are in the Julian calendar system, which is automatically extended for dates prior to its adoption on 45-Jan-1 BC. The Julian calendar is useful for matching historical dates. The Gregorian calendar more accurately corresponds to the Earth's orbital motion and seasons. A "Gregorian-only" calendar mode is available if such physical events are the primary interest. REFERENCE FRAME AND COORDINATES Ecliptic at the standard reference epoch Reference epoch: J2000.0 X-Y plane: adopted Earth orbital plane at the reference epoch Note: IAU76 obliquity of 84381.448 arcseconds wrt ICRF X-Y plane X-axis : ICRF Z-axis : perpendicular to the X-Y plane in the directional (+ or -) sense of Earth's north pole at the reference epoch. Symbol meaning: JDTDB Julian Day Number, Barycentric Dynamical Time X X-component of position vector (km) Y Y-component of position vector (km) Z Z-component of position vector (km) VX X-component of velocity vector (km/sec) VY Y-component of velocity vector (km/sec) VZ Z-component of velocity vector (km/sec) Coordinate system description: RTN: The axes of the RTN coordinate system are the orthonormal basis vectors R, T, and N. R and N are defined by physical parameters, while T completes the right-handed system. R is the radial direction and positive in the direction from coordinate origin to target point (instantaneous range vector) T is the transverse direction perpendicular to the radial direction and positive in the general directional sense of the relative velocity vector (but not necessarily parallel to it); T= N x R N is the normal direction perpendicular to the plane defined by N = P x V, where P and V are position and velocity vectors with respect to the coordinate origin Symbol meaning: R_s Radial direction 1-sigma position uncertainty (km) T_s Transverse direction 1-sigma position uncertainty (km) N_s Normal direction 1-sigma position uncertainty (km) VR_s Radial direction 1-sigma velocity uncertainty (km/sec) VT_s Transverse direction 1-sigma velocity uncertainty (km/sec) VN_s Normal direction 1-sigma velocity uncertainty (km/sec) ABERRATIONS AND CORRECTIONS Geometric state vectors have NO corrections or aberrations applied.
