ARISSat-1, by our observation, has been an operational success-judging by the flood of contact reports on the AMSAT Bulletin Board, posting of hundreds of SSTV photos at the ARISS SSTV Gallery, and submission of over 100,000 frames of telemetry. We had simple goals: make it easy to operate by allowing people to use existing amateur radios, scanners, and computers with sound cards.

We had simple goals: make it easy to operate by allowing people to use existing amateur radios, scanners, and computers with sound cards.
Then it occurred to us that we should conduct an online survey to validate our choices of mission features. Canvassing the team, we came up with questions on what people’s operating parameters (experience, equipment, etc.) were to help us learn how they are using ARISSat-1, and give us some feedback and ideas on what we can do for future amateur-radio and educational-outreach satellites. The survey remains open on Survey Monkey.
Below are the survey results from one week’s worth of responses; unabashed, with no analyses or judgment. I’ll leave that up to you. More than 500 people completed the survey. Many of the questions had respondents selecting multiple answers, thus the total percentages can add up to more than 100 percent. I arranged the order from highest percentage to lowest.
Afterwards, I’ll summarize our current plans for changes and improvements to the next satellite project.1. How did you listen to ARISSat-1?

In order of most frequently mentioned: SSTV, Transponder, Telemetry, Voice
I think the results are a little skewed to the North America side because the announcements for taking the survey originated out of the United States. I am confident that, as the survey continues and the word spreads, the results will flatten out. The first week in November, I will present six weeks’ worth of survey results at the AMSAT Space Symposium
in San Jose and post to the ARISSat-1 Official web site. What’s Next?
AMSAT has announced that they will be working on two new satellites, Fox-1 and Fox2. The Fox Project
, as it is known, will be CubeSats
. Fox-1 will be an easy-to-operate, FM transponder satellite, one with very similar operating characteristics to those of AMSAT OSCAR-51
. Fox-2 will be developed following and using experience gained from Fox-1.
Fox Satellite Concept
Building on lessons learned from AO-51 and ARISSat-1, and inspired by the longevity of AO-7
, the Fox-1 satellite project will introduce the concept of designed-in, partial-failure operation. The satellite will be specifically designed so that when the battery fails, the transponder can continue to operate when the satellite is in sunlight. Similarly, the satellite will be designed so that the FM transponder can operate without relying on the IHU. These modes are intended to extend the usable life of the satellite.Signing off, for now
Wow, can you believe that this has been the twelfth weekly post of the Chips in Space blog? It’s been a fun three months. I hope that you have enjoyed reading the blog as much as I have enjoyed writing it. Thanks for all your comments, questions and encouragement. That is what fuels a project like this.
I’ll update the blog on the mission and operation of ARISSat-1, in the future. Let’s see how she fares in space, over time.
Until then, I must start work on the next great project. Sigh; there are so many fun things to do, and so little time.
