Our solution for satellite communication

At qtlabs, we proudly offer top-tier Optical Ground Station (OGS) solutions designed for both optical laser and quantum communication applications. Engineered for compatibility with GEO and LEO satellites, our OGS systems are tailored to meet the stringent demands of modern optical communication missions.

Versatile and High-Performance Design

Our OGS systems feature:

Telescope Apertures: Ranging from 40 cm to 100 cm, ensuring optimal signal collection and transmission capabilities.
Precision Fork Mount: Oversized, ultra-stable fork-mount structures deliver exceptional pointing accuracy during high-speed satellite tracking.
Optional Optical Path Configurations:
- Nasmyth Ports (available on one or both sides of the mount)
- Cassegrain-Focus Ports for direct free-space signal integration
- Coudé Path integration for sophisticated optical routing and stability

Quantum Communication Optimization

When used for quantum key distribution (QKD) or other quantum protocols, our OGS systems are designed to deliver:

Extremely low polarization error
Minimal timing jitter
Broad wavelength coverage from ~800 nm to ~1550 nm

Precision Acquisition, Pointing & Tracking (PAT)

Our proprietary PAT system enables:

Highly reliable satellite tracking
Seamless operation with LEO and GEO orbit profiles
Fine-tuned alignment accuracy crucial for quantum links

Integrated Design Solutions

Fully remote operational systems
Protective Dome: Offered in a slit-dome configuration: synchronized with telescope motion to ensure uninterrupted operation in challenging environmental conditions.
Environmental Readiness: Systems can be deployed in both urban rooftop installations and remote high-altitude observatories, maintaining performance in a wide range of settings.
