EyeStar-S4

Iridium Enabled Sat-to-Sat Radio

180+ In Orbit | No Ground Stations Needed

The EyeStar S4 is an L-Band radio transceiver providing 24/7 access for up/downlink with latency ranging from 5-30 seconds and data rates of <13.5 bytes/sec. 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% On-orbit success, works in 12rpm tumble, autonomous H&S beacon.

History of the EyeStar Radio

NSL was founded following the successful completion of the TSAT mission in 2014 on which the EyeStar was born. The mission proved one could effectively connect 24/7 to a satellite using an EyeStar radio, then via the Globalstar constellation. Since 2014 more than 180+ customers have flown an EyeStar variant. Each version of the EyeStar has introduced more stability and options for customers, leading us to the most advanced and powerful EyeStar to date.

NSL and Iridium

Iridium operates a low-earth-orbit (LEO) constellation of 66+ satellites that provide mobile satellite voice and data products and service packages connecting customers to the space-based network. Customers around the world in industries such as government, emergency management, marine, and oil & gas rely on the Iridium constellation to be smarter and faster.

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. Now on the Iridium network, the EyeStar S4 provides customers with up and downlink in seconds; 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.

EyeStar S4 on the Iridium network means 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.
