EyeStar-S4
Space-to-Space Communications
215+ In Orbit | No Ground Stations Needed
The EyeStar S4 is an L-Band radio transceiver providing 24/7 access for up/downlink with latency as low as 10 seconds and 10-202 byte packets. With a notably low SWaP-C footprint and no ground station requirement, the S4 is a revolutionary end-to-end communication system. Customers access data and commanding capabilities via the web-based NSL Console or directly with your existing infrastructure via API. 100% Commercial On-orbit success, works in 10rpm tumble, autonomous H&S beacon.

History of the EyeStar
In 2014, NSL engineers successfully developed one of the first successful radios operating on space-based networks, freeing operators from reliance on ground station contact for low bandwidth connectivity. The EyeStar S4 provides customers with up and downlink in seconds; is able to reach your data or send command signals via the HTML-based NSL Console or directly into your existing mission command system through API.
With the EyeStar S4 space-to-space communication network you have 24/7, near real-time access to your satellite during all mission phases; reducing risk on deployment and early orbit ops by providing immediate global contact, then once on mission, send any-time/anywhere payload commands and stay connected via autonomous beaconing of health and safety data, leverage historical data for failure analysis, and more.
