Week in Space Data, every Friday.
Satellite tracking, orbital mechanics, link budgets, and mission planning, all in one browser-based platform. No licenses, no installs, no barriers.
Legacy engineering software is expensive, siloed, and stuck in the desktop era.
STK licenses cost $10K+ per seat. MATLAB add-ons, proprietary orbit propagators, and specialized RF tools add up quickly for small teams and startups.
Engineers juggle between orbit propagators, link budget spreadsheets, thermal tools, and mission planning documents with no shared data layer.
Many available online calculators use simplified models and haven't been updated in years. You need tools you can trust for real mission design.
Professional-grade tools accessible from any browser, on any device.
We'd love to hear how SpaceNexus tools are powering your mission design and engineering workflows.
Share your SpaceNexus story →Yes. Core engineering tools including the satellite tracker, orbital calculator, and link budget tool are available on the free plan. Advanced features like constellation optimization and mission planning are available on paid plans.
SpaceNexus uses SGP4/SDP4 propagation models for satellite tracking and validated Keplerian mechanics for orbital calculations. Results are suitable for preliminary mission design and trade studies.
Yes. All calculators support CSV and JSON export. Constellation designs can be exported in standard formats compatible with STK, GMAT, and other analysis tools.
SpaceNexus complements rather than replaces high-fidelity tools. Use SpaceNexus for rapid trade studies, preliminary design, and real-time monitoring, then move to STK or GMAT for detailed mission analysis.
