The Elas Scientific Production Association is also a principal participant in the proposed Kuryer communications system of Convert spacecraft. The current network design calls for 8-12 of the 500-kg satellites to be deployed in 700 km orbits with 76 degree inclinations by the Start-1 launch vehicle. With a primary objective of supporting "e-mail" and other communications, the Kuryer system may operate at 430-470 MHz with helical antennas and later at L-band with phased array antennas. Optical satellite cross links have also been mentioned. The small spacecraft will be powered by two long, narrow solar arrays and will reject heat via a liquid radiator. The flight testing program was to begin in 1993 but was delayed until 1995 at the earliest (References 261, 272-274).
