SMAD Portal vs Ansys STK
Trajectory analysis vs complete mission engineering workspace
Teams using STK for orbit analysis and evaluating tools to manage the rest of the mission lifecycle
- You need industry-standard orbit propagation and high-fidelity trajectory analysis
- Your workflow requires STK-specific integrations with SOCET, Systems Tool Kit Pro modules, or MATLAB
- You are producing formal trajectory deliverables that customers explicitly require from STK
- You need 3D visualization of coverage, access, and conjunction analysis at STK’s fidelity
- You need more than trajectory — requirements, risks, phase gates, and budgets in one place
- Your team is evaluating mission architecture before committing to high-fidelity trajectory work
- You want an AI trajectory optimizer that proposes candidate transfers for fast iteration
- You need a workspace that a full mission team can use, not just the flight dynamics group

Hand off the selected trajectory to STK for final analysis and customer deliverables
Frequently Asked Questions
Does SMAD Portal replace Ansys STK?
No. STK remains the industry standard for high-fidelity trajectory propagation, coverage, access, and conjunction analysis. SMAD Portal provides lighter-weight propagation (Hi-Fi Propagator, Orbit Determination, Collaborative Orbit Designer, AI Trajectory Optimizer) suitable for early-phase trades and design iteration. Most programs use both.
What orbit analysis does SMAD Portal include?
Orbit propagator, orbit calculator, orbit maneuver planning, launch window, orbit decay, stationkeeping, ground track, coverage, revisit time, eclipse analysis, conjunction screening, and an AI trajectory optimizer that proposes multi-burn transfers.
Can SMAD Portal import STK scenarios?
Not directly. SMAD Portal reads trajectories from ephemeris files and supports TLE, SPICE kernels, and JSON initial-state formats. For formal STK deliverables, export trajectories from SMAD Portal in standard formats and import them into STK.
How does pricing compare to STK?
SMAD Portal starts at $29/month per user. Ansys STK starts in the mid-four-figure per-seat range annually, with modular add-ons for SGP4, astrogator, conjunction, etc. Teams that need STK-level fidelity will continue paying for STK. SMAD Portal covers the rest of the mission lifecycle at a fraction of the cost.
