SkyMar — Validation and release notes
Version 1.1.0 · build 6
SkyMar 1.1.0 provides local celestial calculations and global WMM2025 magnetic variation, with a new launcher icon, welcome, About and Settings pages. The coach and AI assistant have been removed.
Reference validation
Calculations were compared against official reference data within documented tolerances. These comparisons are SL-Mar's validation work; they do not imply certification or endorsement by the reference organisations.
- USNO celestial navigation: 20 cases and 80 angles, within 1 arcminute.
- Additional USNO altitude corrections, sidereal time and event comparisons.
- NASA/JPL Horizons: Sun, Moon and five naked-eye planets; 14 angles within 1 arcminute.
- NOAA solar position and twilight comparisons.
- WMM2025: 100 official magnetic-field vectors, 13 global surface reference points, and a 1,368-point domain grid.
The release suite includes 318 tests, covering the calculation functions, projection, formatting and URL-decoding and update-metadata regression checks.

Scope
This is a finite validation matrix, not a proof for every date, coordinate or field observation. Atmospheric conditions, sextant and clock errors, horizon quality and observer technique affect real observations. WMM2025 has a 2025–2030 model validity period.
Installation
Android 7.0 or later. Beta users need a one-time reinstall because production uses a new signing key. Read the installation and settings-preservation instructions.
