We’ve recently upgraded our Portable Satellite Station 2.0 to add digital and packet capabilities. The upgrade was pretty simple – we added a SignaLink USB Soundcard and a Windows Laptop PC. Most of the software for Packet and Digital Amateur Radio communications is written for the Windows OS so using a separate laptop running Windows 10 was the simplest way to go.
Another benefit of the second laptop was added screen space to use when doing packet communications via satellites and the International Space Station (ISS).
The video above was made during the reception of an SSTV image from the ISS during a pass over the United States. The video gives a good idea of what its like to receive SSTV from the space station.
More ISS SSTV Images…
We were able to receive several different images from the ISS during the period that it was transmitting SSTV worldwide.
It was pretty easy to capture the SSTV transmissions from the ISS with our Portable Satellite Station 2.0 setup. The signals were strong and I would imagine that the SSTV transmission could have also been received with a simple portable satellite setup with a hand-held yagi antenna.
We hope that the ISS will send SSTV images again in the near future. It was fun receiving them.
The video above is a capture of the school’s contact. It was very easy to receive the ISS downlink on our portable backup ground station. I heard the downlink a few seconds before the ISS came up on the horizon and the audio was solid for the duration of the contact. We can only hear the astronaut’s side of the contact as we cannot receive the school’s uplink from Raleigh, NC. The ISS pass began here in New Hampshire part way through the school’s session so we did not hear the first few questions.
Update on Portable ISS/Sat Station 3.0
Work on our upgraded primary Portable 3.0 Station which includes a larger antenna system using switchable circular polarity is progressing well. The portable tower, upgraded rotator system, and the new, larger 2m and 70cm circularly polarized antennas are complete. We are just waiting for a few additional components to arrive here and the upgraded portable ground station should be ready for its first test at our Technician License Class later this month.
More on Today’s ISS Crew Contact
You can see a live stream of the ISS Contact from the school above. There is a great deal of planning which goes into an ISS Crew Contact such as this. We are working closely with Hudson Memorial School on their project and their school is also beginning a High-Altitude Balloon Project with us in a few weeks.
The ISS Crew Contact today was exciting to listen too and we are looking forward to being able to share this experience with Hudson Memorial School in the near future.
