EO-80 (QB50p2)

EO-80, also known as QB50p2, is a 2U cubesat (10cm x 10cm x 20cm) built and launched as a collaborative effort led by the von Karman Institute and ISIS-BV. The primary function of the satellite is testing of the systems designed for the QB50 mission cubesats, including the Attitude Determination and Control System, Ion & Neutral Mass Spectrometer, Oxygen Flux Probe, Satellite Control Software, and the Quadpack deployer. Additionally, the satellite carries a AMSAT-F constructed repeater as a return favor for support of the use of the amateur bands for the primary QB50 mission. Unfortunately the primary transceiver was damaged during a test of the repeater, and the repeater is power negative. Further activation of the repeater is unlikely at this time.

Frequencies are as follows:

• 145.880 MHz 1k2 BPSK or CW Telemetry

• FM Voice Repeater

– 435.080 MHz 210.7 HZ PL Tone Uplink

– 145.840 MHz Downlink (also 9k6 FSK data)

Launched June 19, 2014 on a Dnepr rocket, EO-80 was placed in a 622 x 606 km sun-synchronous orbit, inclined 97.98 degrees. NORAD ID 40032, International Designation 2014-033Y
