ARISS APRS Testing

ARISS APRS Testing

The ARISS team has been working very closely with NASA and ESA to identify potential ARISS radio anomaly causes and resolve the radio issues that were observed after the EVA (spacewalk) conducted on 27th January 2021. During this spacewalk, cabling was installed to support the commissioning of the Bartolomeo attached payload capability mounted on the Columbus module. Part of this cabling rerouted the cabling of the ARISS antenna on Columbus to the ARISS radio system.

Through a great deal of coordination with NASA and ESA, ARISS will be conducting a set of APRS tests to determine the operational use of the ARISS radio system in Columbus through the employment of three different cabling configurations. Over the next couple of days, ARISS will be performing a series of tests using our APRS capability through the standard 145.825 MHz APRS frequency. The crew will be periodically shutting down the radio and swapping cables so ARISS can troubleshoot the radio system and the cabling. ARISS is unsure of the exact swap times as it will be dependent upon the crew’s availability.
