The NSL Black Box
Detect failures before they start with autonomous H&S beaconing and visibility from pole-to-pole; hours before traditional ground station contact.
What is a Black Box?
Based on the idea of Black Boxes for terrestrial commercial aviation, NSL developed a powerful communication, risk-reduction, and situational awareness system for satellite operators. The NSL Black Box comes in three form factors serving a wide variety of mission needs. In all variants, the EyeStar S4 transceiver is coupled with the NSL GPS to bring the power of 24/7 connection to autonomous H&S, TLE, up/downlink connections plus a host of optional add-ons. Black Boxes in all forms can be configured and manufactured to integrate as a stand-alone “barnacle” with its own independent life support separate from the satellite Bus. This means that even in a failed state, operators can gather key data and provide mission-critical restart commands, all while relaying TLE directly to the 18th Squadron from deployment through re-entry.
