Control Center HMI.
Now in the browser.
SammiWeb is the browser-native HMI platform for satellite operations, process control, energy dispatch, and any environment where real-time interactive visualization for command & control is mission-critical — no plugins, no VPN, no desktop install.
Built for the world's most demanding operations centers. 30 years of production heritage. Now browser-native.
Real-time displays.
Any browser. Any device.
RuntimeWeb renders 40+ display object types in any modern browser — meters, trends, bar charts, push buttons, animated graphics — all streaming real-time data via WebSocket at up to 50 Hz.
- Sub-second data latency for mission-critical ops
- No X11, no VPN, no client install
- Existing SAMMI displays migrate with zero code changes
Build and edit displays
directly in the browser.
StudioWeb is the browser-based display editor. Create pages, place display objects, bind live data sources, and configure properties — all from your browser, no desktop software required.
- Drag-and-drop DDO palette with 40+ object types
- Live property inspector with real-time preview
- Save, load, export, and import — all from the browser
Connect to anything.
Stream everything.
The SammiWeb gateway connects to your data infrastructure — OPC-UA servers, MQTT brokers, YAMCS telemetry, key-value stores, and existing Sammi peer applications — all streaming to the browser in real time.
From ground tracks
to 3D globes.
Purpose-built visualization for space operations. Ground Track DDO shows satellite orbits on 2D maps with real-time position, sensor footprint, and ground stations. Cesium Globe DDO renders the same data on an interactive 3D globe.
- TLE-based orbit propagation with auto-refresh
- Sensor footprint and ground station overlays
- Air-gap compatible — all assets served locally
Built for critical infrastructure.
From satellite ground systems to refinery control rooms — SammiWeb delivers browser-native visualization where reliability is non-negotiable.
Why SammiWeb?
Traditional HMI platforms lock you into proprietary desktops, VPN tunnels, and X11 forwarding. SammiWeb breaks free — delivering industrial-grade visualization through the browser.
Zero Desktop Footprint
Chrome, Firefox, Edge, Safari. Desktop, tablet, phone. No X11, no VPN, no client software to install or maintain.
Real-Time Performance
Sub-second data latency at 10–50 Hz via WebSocket. Built for control rooms where milliseconds matter.
Battle-Tested Heritage
Built on the Sammi platform — 30+ years in production on U.S. Space Force SBIRS and defense programs.
Choose your path.
Whether you're modernizing an existing system or starting fresh — SammiWeb fits.
Modernize without rewriting.
Your existing display files and peer applications work with SammiWeb out of the box — zero code changes, zero redesign. Your operators get browser access today.
- Same ASC/FMT formats
- Same peer application API
- Side-by-side with legacy SAMMI
Start with a modern foundation.
Build your HMI from the ground up with a browser-native platform. Design displays in StudioWeb, connect any data source, and deploy to any device — all without legacy dependencies.
- OPC-UA, MQTT, YAMCS, REST
- Browser-based design tool
- Air-gap and on-prem ready
