Lessons Learned in the First Year Operating Software Defined Radios in Space

Abstract: Operating three unique software defined radios (SDRs) in a space environment aboard the Space Communications and Navigation (SCaN) Testbed for over one year has provided an opportunity to gather knowledge useful for future missions considering using software defined radios. This paper provides recommendations for the development and use of SDRs, and it considers the details of each SDR's approach to software upgrades and operation. After one year, the SCaN Testbed SDRs have operated for over 1000 hours. During… Show more

“…As discussed in [6,7], the flexibility enabled by SDRs also bring complexity to operations. The radios have a large number of parameters to modify link configurations and to improve performance, but these changes could add risk to a mission through operator burden or misconfiguration To reduce the complexity of SDRs, optimize the performance and operation of SDR communications, and investigate autonomous communications operations these on-orbit flexible radios are now being used to enable research on cognitive space communications, the next frontier on communications systems.…”
