SelenSync utilizes high-precision celestial mechanics integrating Astronomy Engine alongside NASA SPICE and International Astronomical Union (IAU) lunar pole coordinate frames. Topocentric conversion accounts for the Moon’s mean radius (1,737.4 km), correcting for selenographic latitude and longitude parallax with sub-second temporal resolution.
Artemis & CLPS Priority Landing Zones
High-resolution elevation and illumination datasets derived from Lunar Reconnaissance Orbiter (LRO) altimetry.
Comparative Altimetry & Telemetry Matrix (NASA LOLA 128 ppd Altimetry, ~237m/px)
NASA LRO Altimetry360° Polar Horizon Profiler & Shadow Masking
At the Lunar South Pole, the Sun grazes the horizon at extreme low angles (< 2°). Surrounding crater rims and mountain massifs cast vast geometric shadow masks that dictate power generation viability.
Low-Elevation Polar Insolation
Because the Moon has an axial tilt of only 1.54°, the Sun never climbs high in polar skies. A 1,000m ridge 30km away can block sunlight for weeks.
360° Azimuthal Skyline Profiling
Raymarching digital elevation maps (DEM) sampled every 1° of azimuth calculates the exact obstacle horizon angle θ_horiz(φ) from the lander's coordinates.
Occultation & Battery Survival
When solar elevation drops below the obstacle skyline, power drops to 0W and cryogenic heaters engage, computing battery state-of-charge decay.
Direct-To-Earth (DTE) Communication Windows
Without an active orbital lunar relay satellite, commercial landers rely exclusively on direct RF line-of-sight to NASA’s 34-meter and 70-meter ground stations.
Lunar Libration (±6.7° Lat / ±8.0° Lon)
Earth does not stay stationary in the lunar sky. The Moon’s orbital eccentricity and obliquity cause Earth to trace an apparent Lissajous loop, dipping below the horizon for days at a time.
DSN 3-Station Global Handover
SelenSync models real-time visibility across NASA DSN 34m Beam Waveguide/HEF stations: Goldstone (DSS-24, USA), Canberra (DSS-34, Australia), and Madrid (DSS-65, Spain) as Earth rotates.
Link Budget Margin (> +3.0 dB)
Computes carrier-to-noise ratio (C/N0), free-space path loss (FSPL ≈ 222.7 dB @ 8.45 GHz downlink), and lander antenna pointing angles ensuring +3.0 dB to +23.6 dB margin.
