A SPACE WEATHER RESEARCH PAYLOAD
ON THE CASSIOPE SATELLITE
The Enhanced Polar Outflow Probe (e‑POP) is a research payload on the CASSIOPE spacecraft that is collecting new data on space storms and associated plasma outflows from the Earth’s ionosphere.
Discover and download e-POP data and visualization tools.
CASSIOPE is comprised of three working elements that use the first made-in-Canada multi-purpose small satellite platform in the Canadian Small Satellite Bus Program, an element vital to the future of the Canadian space program.
The CASSIOPE/e-POP mission is a collaborative effort by researchers from several Canadian and foreign universities and research institutes, as well as Canadian industry. Funding for the mission is provided by the European Space Agency.
The Enhanced Polar Outflow Probe (e-POP) is a research payload on the CASSIOPE spacecraft that is collecting new data on space storms and associated plasma outflows from the Earth's ionosphere.
Launched on September 29, 2013 by a SpaceX Falcon 9 rocket, e-POP is enabling scientists to study space weather and its potentially devastating impacts on radio communications, GPS navigation, and other space-based technologies.
The University of Calgary is leading the operation of e-POP, which is the first made-in-Canada multi-purpose small satellite mission from the Canadian Space Agency.
The 18th e-POP Science Team Meeting will take place on February 21-23, 2018 at the University of Saskatchewan, Institute of Space and Atmospheric Science (ISAS) in Saskatoon. The meeting will feature program updates, scientific workshops, and special presentations to recognize our retiring and emeritus team members for their contributions to the e-POP mission.

A new Radio Science publication shows the validation of the e-POP GAP Occultation experiment data. Using a number of methods to validate the receiver’s differential code bias, lead author Dr. Chris Watson of the COSMIC Program Office at UCAR shows that total electron content measurements from the GAP occultation receiver are in good agreement with Read more about e-POP GAP Occultation data validation published in journal Radio Science[…]
A new publication in Geophysical Research Letters, lead by Dr. David Miles of the University of Iowa, makes use of e-POP and Swarm in-situ satellite data over Northern Canada to address the question of the energy source for dynamic aurora: static electric fields or magnetic waves? It is shown that magnetic Alfvén waves can be Read more about New e-POP – Swarm publication on auroral dynamics[…]
The American Radio Relay League (ARRL) Field Day is an event where more than 40,000 ham radio operators throughout North America set up temporary transmitting stations in public places. During the 2015 event, e-POP listened in for just a couple of minutes to see what it could hear. Unsurprisingly, it recorded some very interesting data Read more about e-POP to Participate in 2017 ARRL Field Day[…]
We have a new-look website! Let us know of any ways we can improve your experience in the comments. We hope you enjoy the new look and functionality. The CASSIOPE/e-POP Team.
New research on high frequency radio wave propagation through the ionosphere has been published in the journal Radio Science, using data from the e-POP RRI instrument and SuperDARN. Have a look! First results of HF radio science with e-POP RRI and SuperDARN
Happy Anniversary! CASSIOPE was launched three years ago today, on September 29, 2013. It was a picture-perfect launch from Space-X, inserting CASSIOPE into the an optimal 81 degree inclination with apogee at 1500 km and perigee at 325 km. Here’s to many more healthy years (or as many as we can get before burning up Read more about CASSIOPE Celebrates Three Years in Space[…]
The 17th e-POP Science Team Meeting was held June 15-17, 2016 at Natural Resources Canada, Geomagnetic Laboratory in Ottawa, Ontario. The goals of the meeting were to: Inform attendees of current mission and operation status Help attendees get up to speed on mission data current status and scientific access Facilitate collaborations in anticipation of “Science Read more about Science Team Meeting #17[…]
A new and powerful Java application for finding and downloading e-POP data, called eDEx (e-POP Data EXplorer), has been launched. Use it to search for and download data, quicklooks, summary plots, and satellite ephemeris. Want to know when FAI and RRI were on together? Use eDEx!
