OUTPOST 3M - Computerized clamshell dome for telescopes and space monitoring
OUTPOST 3M is a fully opening, 3-meter diameter computerized dome designed by PrimaLuceLab for astronomy and space applications. Unlike traditional observatory domes that require synchronization between the telescope and the dome shutter, OUTPOST 3M opens completely, giving telescopes unrestricted access to the entire sky. This makes it the ideal solution not only for astronomical observatories but also for fast-response tasks such as satellite tracking, space debris monitoring, and all-sky surveys.
Product Details
Constructed with a multi-layer GRP (Glass Reinforced Plastic) structure and featuring anodized aluminum and stainless steel components, OUTPOST 3M offers greater rigidity and durability, ensuring long-term stability even in demanding environments. High-speed motors and advanced remote-control electronics guarantee rapid opening and closing.
Developed as part of Observatory Stations, OUTPOST 3M combines robustness, automation, and reliability, making it suitable for research institutes, universities, and space economy companies.
Main Features
- Fully opening 3m dome for unobstructed access to the entire sky without the need of synchronization between shutter and telescope position.
- Fast motorized opening/closing for immediate observation readiness.
- Reinforced multi-layer GRP (Glass Reinforced Plastic) structure for superior rigidity and durability.
- Designed for robotic and remote-controlled observatories.
- Automatic safety closure in case of power loss, rain or wind with optional UPS or sensors.
- Seamless integration with Observatory Stations.
- Designed, engineered and built in Italy for professional reliability and long-term operational stability.
FULLY OPENING ARCHITECTURE FOR RAPID AND UNRESTRICTED SKY ACCESS
The clamshell design of OUTPOST 3M allows full exposure of the sky without mechanical constraints. Telescopes are free to operate without requiring dome synchronization. This makes OUTPOST 3M particularly suited for:
- Satellite tracking and Space
- Situational Awareness (SSA)
- Space debris monitoring
- Astronomical events
- Wide-field surveys and automated imaging programs
- University research and long-term observation campaigns
By removing mechanical alignment complexity between dome and telescope, the system simplifies operations while increasing responsiveness.
PRECISION MOTION DESIGN FOR HIGH SPEED SHUTTER OPERATION
OUTPOST 3M features a special design to ensure precise, synchronized and high-speed opening of the four dome shutters. The system is designed to deliver coordinated segment motion with optimized mechanical balance to reduce mechanical stress and enable rapid full-sky access. The four shutters can fully open or close in just 30 seconds, providing immediate operational readiness for rapid-response and critical observations. This is a critical advantage for satellite tracking, space situational awareness and astronomical observations. The result is a smooth, fast and controlled opening system developed for professional remote observatories and advanced installations.
INDUSTRIAL-GRADE CONTROL ELECTRONICS WITH AUTONOMOUS SAFETY LOGIC
OUTPOST 3M is equipped with custom-designed control electronics developed by PrimaLuceLab specifically for observatory automation. The industrial-grade control unit is housed inside a certified IP66 enclosure, ensuring protection against dust and water ingress in demanding environments. This control system ensures instrument safety even in remote and unattended installations. It includes:
- Dedicated remote-control board designed in-house
- Autonomous safety logic independent from external software
- Emergency manual controls
- Automatic closure capability in case of power supply interruption (when connected to optional supported UPS), rain detection (with optional rain sensor) or Wind detection (with optional wind sensor)
REMOTE CONTROL FROM PC WITH DEDICATED ASCOM DRIVER AND FLEXIBLE CONNECTIVITY
OUTPOST 3M is supplied with a dedicated ASCOM driver, enabling full remote control from any astronomy software that supports ASCOM dome control. The dome can be connected to the control computer via USB or Ethernet, providing flexibility in both local and remote installations. OUTPOST 3M is designed to integrate natively with the EAGLE computer and it can be controlled from any Windows 10/11 PC, this way it fits naturally into professional and educational workflows already adopted by space entities, universities, research institutes, and remote observatories.
INTEGRATED TECHNICAL BAY
OUTPOST 3M includes an integrated equipment bay designed to house essential observatory infrastructure components such as:
- Power distribution systems
- Networking equipment
- Control cabinets
- UPS systems
The compartment is capable of accommodating a standard 19” rack cabinet up to 12U, enabling installation of electronics to support the instrumentation. This integrated technical bay allows clean installation, and optimized system integration, improving overall reliability and maintainability of the observatory system.
STRUCTURAL DESIGN AND MATERIALS
OUTPOST 3M is constructed using a reinforced multi-layer GRP (Glass Reinforced Plastic) structure combined with anodized aluminum components and stainless steel hardware. The multi-layer composite structure is engineered to provide rigidity while maintaining manageable weight and ease of installation. The external surface is finished with a professional two-component paint selected for demanding outdoor and industrial environments. The internal surface is treated with a low-reflectivity coating to reduce unwanted internal reflections during observations. Every element of the dome is designed for long-term outdoor operation and stability, with particular attention to mechanical alignment and environmental exposure. Designed and engineered in Italy, OUTPOST 3M reflects PrimaLuceLab’s approach to precision mechanics, system integration, and automation-focused architecture.
PROTECTED CLOSURE INTERFACE
Special attention has been given to the closure interface between the dome segments. The closing line is engineered to improve protection in the most exposed junction area of the structure. The reinforced contact geometry enhances closure at the meeting point of the segments, contributing to increased instrument protection during adverse weather conditions.
DESIGNED FOR REMOTELY CONTROLLED OBSERVATORY STATIONS
OUTPOST 3M has been developed as part of PrimaLuceLab Observatory Stations, ensuring seamless integration with:
- Computerized telescope mounts
- Remote control systems
- EAGLE control computers
- PLAY software for Windows
- Third-party software through ASCOM drivers
The dome is designed to operate as part of a coordinated platform, supporting single telescopes, multi-telescope installations, or complete remote observatories.
PRE-ASSEMBLED STRUCTURE FOR A SIMPLIFIED INSTALLATION
OUTPOST 3M is designed to move from shipment to operation in the quickest way: in fact it’s fully pre-assembled and tested at PrimaLuceLab headquarters before shipment. Then, the dome is shipped worldwide in two main pre-mounted sections on dedicated pallets. Installation on site is straightforward: the two halves are joined together, mechanically secured to the foundation, and the power and motor connections are completed. This approach drastically reduces installation time, eliminates alignment uncertainties, and minimizes the risk of structural inaccuracies that can occur with piece-by-piece assembly. For universities, research institutes and space economy infrastructures, this means faster commissioning, predictable installation procedures, and reduced dependence on complex on-site construction phases.
