The REALM software team reached a major milestone recently deploying an on-orbit software upgrade to the REALM-1 system on the International Space Station. This upgrade’s main feature allows better compatibility with other RF systems onboard the vehicle and also includes various other enhancements to commanding and telemetry of the system. Congratulations to the whole team making this a success! We look forward to new RFID based technologies currently in development that will extend the inventory management capabilities of the REALM system and help the ISS crew succeed in their mission!
