via the ARRL: ARISS Next Generation Radio System Completes Critical Flight Certification Tests

The Amateur Radio on the International Space Station (ARISS) next-generation Interoperable Radio System (IORS) successfully completed a battery of stress tests, required as part of the final certification of the hardware for launch to and operation on the International Space Station (ISS). The IORS consists of a JVC Kenwood D710GA transceiver and the AMSAT-developed Multi-Voltage Power Supply (MVPS). In early July, the equipment successfully completed a series of electromagnetic interference/electro-magnetic compatibility (EMC) tests to ensure that the ARISS hardware will not interfere with ISS systems or other payloads.

The IORS also successfully passed power quality and acoustics testing, which verified that the ARISS IORS will not introduce harmful signals back into the ISS power system and is quiet enough to meet ISS acoustic requirements. ARISS Hardware Team members Lou McFadin, W5DID, and Kerry Banke, N6IZW, were at NASA’s Johnson Space Center to support the 2-week battery of tests in concert with the NASA test and certification team.
