Following the completion of the move of the VT SuperDARN group to new on-campus quarters, the group website is now undergoing a thorough updating, a process that may take several months. Temporary interruptions in some services are possible. If you have a time-critical need for a product that is unavailable, please contact a group member listed under 'Contact/Visit Us'.

Over the course of August and September of 2020 the SuperDARN radar group, with its offices and lab, re-located from a building in the Corporate Research Center on the outskirts of Blacksburg to a location near the heart of campus. This was part of the move of the Center for Space Science and Engineering Research (Space@VT) which counts groups in the ECE and AOE departments. Owing to covid-19 circumstances actual activities in the new areas remain limited with most people accessible by email and Zoom. The new quarters for the SuperDARN group are located on the 3rd floor of Durham Hall. Details of our new mailing address are given in 'Read More'. We look forward to welcoming visitors in our new quarters!

PRIC Visitor Jianjun Liu makes working trip to the Blackstone radar

Dr. Jianjun Liu from the Polar Research Institute of China (PRIC) made a working trip to the SuperDARN Blackstone site on January 13, 2020 and assisted in bringing this radar back on line. The crew included SuperDARN regulars Kevin Sterne and Mike Ruohoniemi and Virginia Tech undergrad Ian Kelley who performed significant diagnostics on the damaged parts. The PRIC is a member of the international SuperDARN collaboration (PI: Dr. Hongqiao Hu) and operates a SuperDARN radar at the Chinese Antarctic base at Zhongshan Station where Jianjun wintered over during a 14 month stay. He has been visiting the VT SuperDARN group since December and will return home later this week. The photo shows (from left to right) Jianjun, Kevin, and Mike standing in front of the Blackstone electronics.

On April 25 a group of visitors was led by Kevin Sterne to make a tour of the Blackstone SuperDARN radar. Drs. Nozomu Nishitani and Tomo Hori and graduate student Kento Oya from ISEE Nagoya University were joined by Dr. Erxiao Liu from Hangzhou Dianzi University. The photograph shows the Japanese visitors with Kevin and towers of the two arrays and the equipment shelter in the background.

Kapuskasing Aug. 2018 Trip

By: ksterne  on: Fri., Feb. 01, 2019 10:55 AM EST  (3402 Reads)
During the installation of the low loss coaxial cable in Oct. 2015, only the main array had new ground coax cable installed as time ran out to finish installing ground coax cables to the interferometer array. With a push from Simon Shepherd at Dartmouth College to get more radars collecting elevation angle, a trip to the Kapuskasing radar was planned for Kevin Sterne, Paul Kennedy, Mike Ruohoniemi and Simon Shepherd. In addition to installing the ground coax cables, the condition of the antennas along both array and the transmitters would be investigated and checked as the last service trip was the Oct. 2015 trip. Lastly, this trip was necessary to install signage around the site in order to comply with safety standards with the Canadian government.

Blackstone Trip, July 2018

With the visit of FHSU student intern Kelly Strecker and with the repairs of some transmitters from the May 2018 trip, this trip to the Blackstone radar introduced Kelly to more radar hardware and allowed the installation of the transmitters. The goal with the transmitters was to get all of them firing as all of the antennas were repaired earlier in the year. With the two recently repaired transmitters, the radar was left running on all antennas at the end of this trip. However, two additional transmitters were found to not be running so these were brought back to the Blacksburg lab for repairs. These transmitters will be spares at the site once repaired and returned.

In addition to these items, a check of the electrical lengths along the coax and inside in the electronics was performed as gathering correct elevation angle data has become an emphasis across SuperDARN. The time delay was found to be close to previous values, with some small differences. This new difference will be reflected in the hdw.dat file for Blackstone.
