A glossary of the key terms and mathematical quantities used in the paper.
| Term | Description |
|---|---|
| Argument of Perigee (ω) | Orientation of the ellipse in the orbital plane measured from the ascending node to the periapsis. |
| Baseline | Vector drawn between two telescopes observing the same source orthographically projected to the source. |
| Eccentricity (e) | Elliptical shape of the orbit (0 ≤ e < 1). |
| Delta-v (Δv) | The change in velocity required to perform a given manoeuvre. |
| Diffractive Taper | A model for Sgr A*’s diffractive scattering effects. |
| Downlink | A link from orbiter to an Earth station to perform data transfer. |
| Inclination (i) | Orientation of the orbit with respect to the equator. |
| Semi-major axis (a) | Size of the orbit (average of the apoapsis and periapsis radii). |
| Specific Impulse (Isp) | A measure of thrust accumulated by a rocket as fuel is burnt. |
| True Anomaly (ν) | Denotes the angular position of the satellite with respect to the peripasis. |
