From Kathryn's emails to the SuperDARN PIs >>>

Hello All,

Thanks for the messages of congratulations and for the questions. In principle, ePOP RRI can receive any SuperDARN signals, as it is designed to receive in the appropriate HF bandwidth. The RRI must be scheduled to receive on the SuperDARN transmitter frequency. The upgrades to the Saskatoon radar that improve the accuracy of the timing between the ground and the satellite should allow us the required accuracy to analyse propagation delays of the O and X modes. I will check with the Engineering team to find out what this upgrade entails and can let you know if you are interested. We can also make available the RCP once it has been well tested and works reliably.

Thanks again,

The scientific instruments are being tested and all goes smoothly, as we understand. The Radio Receiver Instrument (RRI) is designed to receive SuperDARN pulses, and the Saskatoon radar has been modified to achieve more accurate time synchronization with the RRI.

I am very pleased to let you know that RRI has successfully received SuperDARN signals, and the data were successfully transmitted from the satellite. The data analysis is being led by Dr. Rob Gillies, who is now at the University of Calgary. He has sent us a couple of plots to share, and these are attached.

Two sequential 8-pulse sequences are clear in one of the plots, and the other plot zooms in to reveal the detail of the individual pulses. The four panels are the four RRI data channels (essentially, panels 1 and 2 are one dipole and 3 and 4 are the other dipole). In the zoomed view you can see that the pulse lengths are 300 us and RRI records approximately 1.5 wavelengths per pulse. Rob did a quick calculation that 1.5/300us = 5000 Hz. Since the Saskatoon radar was transmitting at 14010 kHz and RRI was receiving at 14005 kHz, it looks like the frequency is correct. The varying intensity of the pulses in the sequence hints at really interesting studies about the Faraday rotation of the radio waves. Rob adds that the UTC time for these plots was ~23:32:42 on 7 Nov 2013. He believes that ePOP was near 66.5 deg geographic latitude, -102.9 degrees longitude, and 363 km altitude.

We are excited about the successful launch of ePOP, and we look forward to doing lots of neat science with the data. We hope that you will look to ePOP to do some interesting experiments also.

With kind regards,
