Space Station over Ottawa Wed 30 March 2011

The International Space Station will pass over Ottawa tomorrow Wed 30 March. It will roar over at an altitude of 300 km and at a speed of 30,000 km/hr. We have authority from NASA to talk with the astronauts on board the space station. The contact will be made from Canterbury High School in Ottawa around 11:00 am local time. The radios from been set up in the school’s theatre and both the directional and vertical antennas are now on the roof. The coaxes have been run and the computers have been programmed. All is ready to go.
We will start calling the space station, NA1SS, at AOS 1456Z (over Winnipeg) and allow the students to ask questions till LOS 1506Z (over Halifax). This will be done during the school assembly.
If you have a VHF receiver you can listen in on the ISS downlink 145.800 MHz FM. There is a Doppler shift of +/- 300 kHz during the orbital passage at the beginning and end of the contact which you may experience. That is normal.
We only have one chance at this. Once the ISS is gone over the horizon, it’s gone.
So wish us luck! There should be media coverage on local newscasts Wednesday night if all goes well.
