FORIMMEDIATE RELEASE

Simultaneous Operations of APRS and VoiceRepeater now a Reality on ISS

ARISS is pleased to announcethat starting yesterday, August 11, simultaneous operations of the ARISS VoiceRepeater and digital APRS communications on the International Space Station(ISS) is now a reality.  Current ARISSoperations include voice repeater transmissions with the JVC Kenwood D710GA inthe Columbus module and APRS packet operation from an identical radio in theService Module (Zvezda).  Packetoperations are on 145.825 MHz.

The ARISS Russia and USAteams have been working for several weeks to prepare the Service Module radiofor APRS operations.  ARISS Russia teammember Sergey Samburov, RV3DR, led the effort, working with Russian missioncontrollers and the on-board ISS cosmonauts to configure the Service Moduleradio for APRS ops.  On August 11, finalcheckouts were completed and the APRS packet mode was switched on for amateurradio use.

ARISS-International ChairFrank Bauer, KA3HDO states, “Simultaneous operation of APRS and the voicerepeater on ISS is transformative for ARISS and represents a key element of ourARISS 2.0 initiative, providing interactive capabilities 24/7 that inspire,engage and educate youth and lifelong learners—especially life-long learning inham radio operations.”  Bauer continues,“Our heartfelt thanks to Sergey Samburov, RV3DR, for making this crucial ARISS2.0 initiative become a reality.”

The Columbus Module radio uses the callsignNA1SS and the new Service Module radio uses RS0ISS.  Aside from the callsigns, the radios areidentical and packet operations are the same as before.  You can use RS0ISS, ARISS, or APRSAT as thepacket path.  Also, both radios areexpected to be on full time, except during educational contacts, EVAs, and dockingsor undockings.

The primary goal of ARISSis to promote exploration of science, technology, engineering, the arts, andmathematics topics. ARISS does this by organizing scheduled contacts viaamateur radio between crew members aboard the ISS and students. Before andduring these radio contacts, students, educators, parents, and communities takepart in hands-on learning activities tied to space, space technologies, andamateur radio.
