Supernova-Beta

Supernova-Beta [Pumpkin]

Supernova-Beta is picosatellite built as prototype of the Pumpkin Inc. Supernova 6U CubeSat bus.

The Supernova-Beta mission is a test flight of multiple subsystems on the SUPERNOVA 6U bus developed by Pumpkin, Inc, including structure, EPS, GPS, ADACS, CDH, and imagers.

The Spacecraft will contain three communications systems. One is transmit-only while the other two are transceivers:

  • Tx-only beacon radio operating at 435 MHz, 1200 bps AFSK modulation, output power 2 W. Used to transmit basic health and status data every 30 seconds and operate worldwide, continuously, except if commanded to be shutdown (via commands sent on Globalstar or S-band). Uses patch antenna with 150 beam (half-power width), peak gain 2.5 dBi.
  • Simplex Globalstar modem designed for satellite-to-satellite communication with the Globalstar commercial satellite network. Used for continuous TT&C purposes worldwide. Tx on 1610 MHz, Rx on 2483.5 MHz; modulation is CDMA. Will use patch antenna with near-180 beam.
  • S-band transceiver, inactive except when passing over ground stations. Used for high-bandwidth data transfers over ground stations. Tx on 2257.9 MHz, OQPSK modulation, 1.0 Mbps data rate, 4 W output power. Rx on 2097.7 MHz, BPSK modulation, 64 kbps data rate. Will use patch antenna with 70 beam (half-power width).

The spacecraft will contain an active attitude control system. All antennas are patch designs, fixed-body mounted, nadir-facing.

The satellite was to be launched on the maiden flight of the Super-Strypi rocket from Hawaii into a 415 km × 490 km polar orbit, but was lost in a launch failure.
