XW 2B, 2C, 2D (CAS 3B, 3C, 3D)

XW 2B (CAS 3B) [CAMSAT]

XW 2B, 2C and 2D or CAS 3B, 3C and 3D (Chinese Amateur Radio satellite 3B, 3C and 3D) are a constellation of three identical Chineses micro-satellite for atmospheric physics experiments and amateur radio missions.

The satellites feature a 246 mm × 246 mm × 246 mm cubic body with body mounted solar cells and a mass of approximately 10 kg mass. They feature a three-axis stabilization system.

The amateur communications payload consists of U/V 20 kHz wide transponders with 145 MHz CW beacon and 19k2 GMSK AX25 telemetry downlinks.

XW 2B, 2C and 2D were launched in a cluster of 20 satellites on the maiden flight of the CZ-6 rocket.
