The Dodecapole satellites, also known as Dodecahedron or Porcupine, were small passive radar calibration satellites built by the Naval Research Laboratory (NRL) for the need for a large target satellite for Space Surveillance System calibration.
Each object is a 26 cm sphere with 12 telescoping hollow rods erected in orbit normal to the faces of an equivalent regular dodecahedron. Each rod is 1.27 cm in diameter and 7.62 m long.
