1967-011A
The 23kg D-1C geodetic satellite was launched in Feb 1967 from Algeria. (D-1B was cancelled). Like the other D-1 satellites, it was built at CNES/Bretigny, based on a structure supplied by Matra.
It carried laser reflectors and a Doppler beacon transmitter for accurate orbit determination. A magnetic stabilization system was added. The apogee was lower than planned, but the mission was otherwise successful.
Some debris objects were cataloged from the launch. 1967-11Q is probably a fragment from D-1D, not D-1C.
