Transit 2A

  1960-007A


The Transit IIA satellite carried the first subsatellite, NRL's GRAB 1 (GREB). It carried an experimental clock, and an Alouette program ionospheric beacon. Launch was southeast over South America, to reach high inclination. The despin weights were on a timer set to deploy after 7 day.s This reportedly did not work and 2A was despun using magnetic effects by late July. However, two objects were cataloged in orbit which may have been the despin weights.

The press kit claimed that the NOTS IR scanner was intended to measure the spin period of the satellite.
