The Canadian CAScade, Smallsat and Ionospheric Polar Explorer (CASSIOPE) spacecraft once again eavesdropped in on the 2018 ARRL Field Day. Onboard CASSIOPE is the Enhanced Polar Outflow Probe (e-POP), a suite of eight science instruments studying spaceweather.

The Enhanced Polar Outflow Probe (e-POP) onboard the Canadian CAScade Smallsat and Ionospheric Polar Explorer (CASSIOPE) satellite will once again be supporting ham radio citizen science by participating in the 2017 American Radio Relay League Field Day, on June 24 and 25, 2017. On an annual basis, the ham radio community participates in the ARRL Field Day to exercise and hone their skills in the field. In essence, it is an emergency preparedness exercise – one of the largest anywhere – with several thousand hams taking part across the world. From a radio science perspective, Field Day is an ideal time for e-POP to study the structure of the Earth’s ionosphere using Field Day participants’ transmissions.
