What is COMPASS for EVE Online?

COMPASS is a free logistics tool for EVE Online that helps capital ship pilots plan jump routes, assign cyno alts to destinations, and coordinate multi-freighter fleet movements. It uses real game data from the EVE SDE and ESI to calculate accurate travel times, fuel costs, and fatigue timers.

How does COMPASS calculate travel time in EVE Online?

COMPASS uses real CCP warp physics (3-phase model: acceleration, cruise, deceleration) with actual gate XYZ coordinates from the SDE. Align time is calculated from ship mass and inertia using ceil(ln(2) x inertia x mass / 500,000). Each gate jump includes 20 seconds overhead (session change, gate animation, grid load, approach). Skills and fitting modules modify these calculations with proper stacking penalties.

Can I use COMPASS without logging in?

Yes. Gate Planner, Jump Planner, and the Dossier intelligence system all work without EVE SSO login. Connecting your EVE account unlocks Cyno Finder (optimal cyno alt assignment), Fleet Planner, character management, and personalized watchlists with real-time gank notifications.

What is the COMPASS Dossier system?

The Dossier is a criminal intelligence database that profiles gankers from zKillboard data. It shows behavioral analysis (fleet commander, solo ganker, pipe camper), activity heatmaps by hour and day, hunting grounds, fleet associates, victim analysis, and an "active right now" probability based on historical patterns.

How does the COMPASS watchlist work?

You can watch up to 5 systems and 5 ganker pilots. When a gank happens in a watched system or a watched ganker gets a kill, you receive an instant push notification via Supabase Realtime. Alerts show in the notification bell with victim details, ISK value, and a link to the zKillboard killmail.

How the Cyno Assignment Algorithm Works

A transparent look at how COMPASS finds the globally optimal assignment of cyno characters to destinations using dynamic programming.

COMPASS doesn't greedily assign the best character to each destination. It considers all possible pairings simultaneously and minimizes total fleet disruption.

The Pipeline

Route Calculation

For every character × destination, calculate 3 routes: Direct (gate travel), Jump Clone (activate + gate), Death Clone (self-destruct + gate). Each uses real EVE physics.

Travel Time

Real SDE data — not estimates. Align time from ceil(ln(2) × inertia × mass / 500,000). Warp distance from actual gate xyz coordinates. Per-jump overhead: 20s fixed.

Disruption Scoring

Each route gets a cost reflecting fleet impact. Clone options carry penalties for implant loss, cooldowns, reship time.

Optimal Assignment

DP bitmask solver tries every permutation efficiently. Finds the assignment that minimizes total disruption across ALL destinations at once.

Direct Travel

Fly through stargates from current location. Uses ESI shortest path. Best when character is close.

Jump Clone

Activate a jump clone near the destination, then gate the remaining distance. Subject to 24h cooldown.

Death Clone

Self-destruct to respawn at home station. Destroys active implants. Heavy penalty — last resort.
