The BPA (Blok Perspektivnoy Avioniki) payloads were packages of experimental avionics monted to the third stage of a Dnepr launch vehicle. The payload were intentionally not separated from the stage.

These packages have been built by the Ukrainian company Hartron-Arkos. They have the purpose to test navigation equipment for civil planes and spacecraft in orbit. During the brief missions, the payloads were powered by the upper stages batteries.

Three BPA payloads have been launched as secondary payloads on three Dnepr flights. BPA 1 flew on 15 June 2010, BPA 2 on 17 August 2011 and BPA 3 on 21 November 2013.
