Column Listing
Column | Column Name | Element | Type | Dimension | Description |
---|---|---|---|---|---|
1 | Time | Time | Real Number or Text | Date | Time. |
2 | Semi-parameter | Semi-parameter | Real Number | Distance | The semi-latus rectum, often designated by the letter p, related to the semimajor axis a and eccentricity e by p = a*(1-e^2). |
3 | Semi-major Axis | Semi-major Axis | Real Number | Distance | A measure of the size of the orbit. Orbits with eccentricity <1 are ellipses, with major and minor axes identifying the symmetry axes of the ellipse, the major axis being the longer one. The value is half the length of the major axis. |
4 | Eccentricity | Eccentricity | Real Number | Unitless | A measure of the shape of the orbit. Values <1 indicate an ellipse (where zero is a circular orbit) and values >1 indicate a hyperbola. |
5 | Inclination | Inclination | Real Number or Text | Angle | The angle between the orbit plane and the XY plane of the coordinate system. |
6 | Arg of Perigee | Arg of Perigee | Real Number or Text | Angle | The angle from the ascending node to the periapsis vector measured in the orbit plane in the direction of the object's motion. The periapsis vector locates the closest point of the orbit. For a circular orbit, the value is defined to be zero (i.e., periapsis at the ascending node). |
7 | RAAN | RAAN | Real Number or Text | Angle | The angle in the XY plane from the X axis to the ascending node, measured in a right-handed sense about the Z axis. in the equatorial plane. For equatorial orbits, the ascending node is defined to be directed along the positive X axis, and thus the value is 0.0. |
8 | Height of Apogee | Height of Apogee | Real Number | Distance | The difference between the apogee radius and the equatorial radius of the vehicle's central body (an approximation for the altitude). |
9 | Height of Perigee | Height of Perigee | Real Number | Distance | The difference between the perigee radius and the equatorial radius of the vehicle's central body (an approximation for the altitude). |
10 | Sidereal Period | Sidereal Period | Real Number | Time | The period of the orbit, computed using the two-body formula involving the semimajor axis and the gravitational constant of the vehicle's central body. |
11 | Orbit Count | Orbit Count | Integer | Unitless | The current orbit count. |
