SOMNIARC · MISSION READOUT

Beyond Limits

§ 01 · MANIFESTO

The Future of Space Infrastructure

Next-generation tools
for managing, simulating,
and designing orbital systems.

Somniarc puts high-fidelity orbital simulation in the hands of every team that depends on the answer — no specialist license, no astrodynamics deep-dive required.

§ 02 · CAPABILITIES

Capabilities · 07

Every analysis your team needs,
in one browser tab.

01 · Propagation

Orbital propagation &
constellation visualization

Load any TLE catalog — single asset to pLEO swarm — and watch it propagate in real time. SGP4 engine, WebGL rendering, country borders, dynamic field-of-regard cones.

  • ◇Live SGP4 propagation, any constellation size
  • ◇Real-time line-of-sight & contact window detection
  • ◇Volumetric day/night Earth shaders with atmosphere glow
SCENE · propagation.mp4
02 · Atmospherics

Real-world atmospheric conditions

Every analysis reflects what's actually happening over the target — not a clear-sky assumption. Live aerosol & weather data feed NIIRS estimates, link budgets, and imaging windows in real time.

  • ◇Live AOD, PM2.5 and PM10 from CAMS Air Quality
  • ◇Effective visibility and atmospheric MTF penalty per pass
  • ◇Combustion, smoke and dust event flagging

03 · Orbital Mechanics

Astrodynamics
made accessible

Real-time SGP4 propagation for any TLE catalog. Visualize full constellations, contact windows, and field-of-regard cones in a browser-native 3D scene.

  • ◇Walker, sun-sync, and custom catalog support
  • ◇Field-of-regard cones with terrain occlusion
  • ◇Realtime ephemeris export
04 · Contact Windows

Multi-satellite
Gantt planning

Generate a multi-satellite Gantt over any planning horizon. See exactly when each satellite is visible to a ground station — with per-pass quality classification baked in.

  • ◇Select any combination from the loaded catalog
  • ◇ANY-SATELLITE composite shows total coverage fraction
  • ◇GOOD / MARGINAL / POOR per-pass classification
  • ◇Configurable horizon up to +5 days

05 · Link Budget

Real-time RF
link budget

Every frame, Somniarc computes a full Ka/Ku-band link budget for each ground station–satellite pair. Slant range, FSPL, rain attenuation, sky noise, SNR — all live.

  • ◇Separate uplink & downlink budgets
  • ◇ITU P.618 rain attenuation + P.372 sky noise
  • ◇Tracking vs. static ground terminal modes
  • ◇Color-coded SNR margin: green / amber / red

06 · Electro-Optical

EO imaging
assessment

Predict collection feasibility before the satellite passes overhead. Set a resolution requirement and generate a full imaging timeline graded against terrain, cloud, sun angle, and atmospherics.

  • ◇Multi-satellite imaging timeline up to +5 days
  • ◇Effective GSD with delta against mission requirement
  • ◇GIQE 4.0 with live atmospheric correction
  • ◇GSD, elevation, cloud % per pass

07 · Terrain

Terrain-aware
horizon masking

Per-azimuth terrain horizon profile for every ground station and imaging target — so contact windows and passes are blocked by real terrain, not a flat elevation cutoff.

  • ◇36-bin azimuth profile at up to 15 km range
  • ◇Copernicus DEM GLO-90 global coverage
  • ◇Log-radial sampling captures ridgelines
  • ◇Per-pass contact gating

§ 03 · INDUSTRIES

Industries · 06

Wherever the mission
reaches beyond limits.

01 · Collection Planning

Collection
planning

Brief stakeholders on what space-based collection can — and cannot — answer over any AOI. Equally well-suited to disaster-response coordination, humanitarian assessment, and infrastructure monitoring. Open-source physics, no ITAR exposure.

  • ◇Tabletop and exercise scenario libraries
  • ◇Disaster & humanitarian-response use cases
  • ◇Air-gapped on-prem deployment available
02 · Commercial Space

Constellation
design & ops

From the first concept-of-operations to live mission ops. Validate orbits, contact coverage, and downlink budgets in the same tool — and share the scenario as a link.

  • ◇Walker / sun-sync / custom catalog builders
  • ◇Ground network optimization
  • ◇Tasking and scheduling exports
03 · Ground Networks

Antenna site planning

Pick the right site before pouring concrete. Per-azimuth terrain masks plus live atmospheric attenuation make the difference between a usable contact window and a wasted CapEx.

  • ◇Multi-site coverage comparison
  • ◇Rain & cloud climatology overlay
  • ◇Aperture-vs-rate trade studies
04 · Academic

Graduate
curriculum

Verified .edu users get full access. Shared scenario libraries are purpose-built for tabletop exercises and course instruction — space policy, ISR, and disaster-response curricula.

  • ◇Shared classroom scenarios
  • ◇Tabletop exercise builders
  • ◇Open physics: SGP4 / GIQE / ITU
05 · Acquisition

Program
analysis

Acquisition officers shouldn't need an aerospace degree to evaluate a vendor's spec sheet. Plug the numbers in, run the orbit, see the realistic resolution and SNR over the AOI.

  • ◇Vendor performance verification
  • ◇Side-by-side trade studies
  • ◇Auditable, exportable reports
06 · R&D

Sensor & payload
development

Prototype a payload in the lab; validate the on-orbit performance envelope before flight. GIQE 4.0 with live atmospheric correction makes lab-to-LEO predictions tractable.

  • ◇Sensor MTF / GSD modeling
  • ◇Link budget Monte Carlo
  • ◇Concept-of-operations validation
§ 04 · ABOUT

About Somniarc

Closing the gap between
simulation and operation.

Somniarc was built to bring orbital simulation to every team that depends on the answer.

Program managers, analysts, and stakeholders across an organization should be able to ask “Can this satellite image that target today, and what will the quality be?” — without standing up a dedicated astrodynamics group to find out.

We combine real orbital mechanics (SGP4/TLE), physics-based payload modeling (GIQE 4.0, ITU link budgets), and live atmospheric data into a browser-native tool that the whole team can share.

§ 05 · ACADEMIC
For Graduate Programs

Free for students
& academic programs.

Somniarc offers a free tier for verified .edu users — including shared scenario libraries purpose-built for tabletop exercises and course instruction.
