BRICSat-P (Ballistic Reinforced Communication Satellite, also OSCAR 83 , formerly ParkinsonSat B or PSat B) is an American technology demonstration and amateur radio satellite .

development

BRICSat-P is a 1.5U Cubesat that was developed and built by students at the United States Naval Academy in collaboration with George Washington University . BRICSat-P is the revised version of the satellite originally called PSat B. After the successful launch, the satellite was assigned the OSCAR number 83.

Mission and Structure

The satellite was launched from Cape Canaveral on May 20, 2015 with an Atlas-5 (501) rocket along with the main X-37B OTV-4 payload and nine other Cubesat satellites, including ParkinsonSAT .

BRICSat-P is used for demonstrating and testing electrical drives . The satellite has four pulsed micro-cathode ray drives µCAT, which are distributed around the center of gravity on one side. These drives are to be used to stabilize the position of the satellite, to test the rotation over two axes and to carry out a delta-v maneuver, which simulates an end-of-life scenario. Orbit analyzes are to be carried out to show that such a micro-cathode ray engine is suitable for a 1.5U Cubesat in terms of power consumption and that the other subsystems of the satellite (e.g. the communication system) can work normally during this time.

BRICSat-P has two amateur radio payloads: a APRS transponders and PSK31 transponders.

Frequencies

  • APRS transponder with downlink to 437.975 MHz and uplink to 145.825 MHz (1200 and 9600 baud AX.25 ).
  • PSK31 transponder with downlink in the 70 centimeter band and an uplink to 28.120 MHz (2.5 kHz bandwidth)
