Key highlights
AstroLink Nano is a compact optical downlink terminal designed for CubeSat and nanosatellite missions. It provides laser communication from LEO to optical ground stations with data rates of up to 2.5 Gbps over slant ranges of up to 1,000 km. The terminal operates at a 1550 nm downlink wavelength with 850/888 nm beacon compatibility, integrates through a 2.5G Ethernet interface, and is optimized for low SWaP platforms with a 1U-compatible form factor and a mass below 1.2 kg.
Applications
AstroLink Nano is designed for LEO CubeSat and nanosatellite missions requiring high-speed space-to-ground data transmission. Typical applications include Earth observation, remote sensing, hyperspectral and SAR data downlink, scientific missions, technology demonstrations, and commercial satellite constellations. The terminal is suitable for missions requiring rapid transfer of large data volumes through compatible optical ground station networks.
