Advanced Astrology Engine & Website Platform for my website (JPL DE431 + NAIF SPICE | without Swiss-Ephemeris) --- Project Objective एक high-precision, licence-free astrology calculation engine और उसके ऊपर बना full-featured astrology website विकसित करना, जिसमें सभी गणनाएँ: Raw JPL DE431 SPK files NASA NAIF SPICE Toolkit (C / CSPICE) के माध्यम से हों और Swiss Ephemeris या किसी भी third-party astrology library का उपयोग न किया जाए। यह सिस्टम commercial-grade accuracy, long-term maintainability, और API-first architecture पर आधारित होगा। --- Core Astronomical & Technical Foundation Ephemeris & Astronomy Engine Raw JPL DE431 SPK files (direct use) NAIF SPICE Toolkit (C / CSPICE) Chebyshev polynomial interpolation (SPK native method) Barycentric → Geocentric transformations TT, TDB, UT1 time systems handling High-precision ΔT handling (configurable models) Observer location based topocentric corrections Sidereal & Tropical framework support --- System Architecture Core Astronomy Engine: C / C++ (SPICE) Calculation API Layer: REST / JSON (FastAPI / Node / PHP wrapper) Website Backend: PHP (Laravel / WordPress Integration Ready) Frontend: Modern responsive UI (React / Vue / Vanilla JS) Modular, API-first, scalable architecture Stateless calculation services Server-side caching for heavy ephemeris calls --- Advanced Kundli Generator (Full Vedic System) Accurate Lagna calculation Planetary longitudes (Graha Sthiti) Bhava calculation (multiple house systems configurable) Nakshatra & Pada computation Rashi & Navamsa charts Shadbala computation Ashtakavarga Dasha systems: Vimshottari Yogini Conditional extension support All Yog detections (configurable rule engine) High-resolution Kundli charts (SVG / Canvas) PDF Kundli export (print-ready) --- Advanced Love Compatibility & Kundli Milan Tool Accurate Guna Milan (Ashta-Koota) Planetary relationship mapping Bhava-to-Bhava compatibility analysis Moon & Nakshatra based emotional mapping Configurable scoring system (logic only, no advice text) API-based result generation Neutral, analytical output (no predictions) --- Advanced Panchang Engine Tithi, Vara, Nakshatra, Yoga, Karana Sunrise / Sunset (true astronomical) Moon phases (exact) Daily, Monthly, Yearly Panchang Festival & Vrat logic layer (data-driven) Location-based Panchang generation API + website view support --- Advanced Rashifal Engine (Non-Predictive) Transit-based planetary position analysis Moon-sign & Lagna-based observation engine Date-range based transit summaries Purely observational / informational No fortune telling, no remedies Output structured as Astro-Data + Neutral Insights --- Advanced Numerology Engine Multiple systems: Chaldean Pythagorean Lo Shu Grid DOB-based core numbers Name-based computation (Unicode safe) Dynamic rule engine Neutral statistical interpretations API + website tools --- Admin & Configuration Panel Enable / disable modules House system selection Ayanamsa configuration ΔT model selection Localization (multi-language ready) Result text templates (non-predictive) --- Deliverables Fully working Astrology Calculation Engine Public & internal REST APIs Full astrology website with tools: Kundli Generator Kundli Milan Panchang Rashifal Numerology Source code + documentation Deployment guide (cPanel / VPS) Performance & accuracy benchmarks Ideal Freelancer Profile Experience with NASA SPICE Toolkit Strong background in astronomy or orbital mechanics Experience handling large ephemeris datasets API design & performance optimization skills Clean, well-documented code practices --- Key Success Criteria Astronomical accuracy matches or exceeds Swiss Ephemeris Fully licence-free commercial usage Modular & extensible architecture Fast response under heavy load Scientifically explainable calculations
