This paper addresses the Asolant/Rubin-5 flight experiment conducted onboard the upper stage of a Cosmos rocket in late 2005. The main objective of the project was to flight-qualify a newly developed combined solar cell/antenna device, the so-called Advanced SOLar ANTenna (ASOLANT) technology. In order to assess both, the reception as well as emission of R/F signals, two different devices were involved in the mission. One was linked to a space-borne Phoenix-S GPS receiver to examine the receiving performance. A second device was designed to send out S-Band beacon signals generated by the SAFIR-S amateur radio transmitter to evaluate the radiation characteristics. Moreover, both ASOLANT devices supplied the electrical power for the onboard systems. Telecommand and telemetry functionalities were provided by an ORBCOMM communicator making use of the ORBCOMM satellite network to relay data between space and ground. This unit, furthermore, served as onboard computer. The experiment was launched along with eight multinational payload satellites. It was designed to remain attached to the rockets upper stage after burnout. Due to a separation failure of one of the copassengers, the primary mission objectives could not be fully met. Nevertheless, a sufficient number of data was retrieved to confirm the good overall performance of the ASOLANT devices. Roughly ten month after the launch, still most system components are operational and experiment data are transmitted to ground. Following a description of the main flight system components and the overall ystem architecture, the paper summarizes the hitherto obtained experiment results.
