Chips in Space - The Building of an Amateur Satellite
10/1/2011 10:08 AM EDT
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.

For those who have been following this blog and the reader comments, you know that the battery failed eight days into the mission. For the next mission, we need to design a power system where a shorted battery will not render the satellite inoperable. Thankfully, the ARISSat-1 battery failed open; but that was luck. For an extraordinary story about amateur-satellite batteries, read how the battery shorted then reopened 21 years later on AMSAT OSCAR 7.

Project management teaches us to do a post-mortem review at the end of every project, to muse about the things that did and didn’t go right. If things went right, they are called “best practices.” If they did not go as planned or we overlooked something, we call them “lessons learned.” A polite way of saying, we goofed and we promise not to do that again (we hope).

It’s a lot of fun telling the tale about ARISSat-1. So, when we were offered a table at the Microchip MASTERs Conference, we accepted the invitation with enthusiasm. For the conference, we shipped in our fully functional demonstration satellite from the East Coast to Northern Phoenix and put it on display.

We’ve covered a lot of ground in the past seven blog posts. The story had a beginning of an idea (hey, let’s fill a suit with electronics and toss it out of the International Space Station!). Twist and turns (we lost the suit, now what?!). Heroic recovery (that’s a nice aluminum space frame you got there!). And a happy ending (We have liftoff! ARISSat-1 is successfully operating in space!).

The third and final chapter on the ARISSat-1’s subsystems, which covers all of the Cs: communications, cameras, control and cabling, along with the university experiment that hitched a ride.

Part 2 of our dive into each of ARISSat-1’s subsystems, where I will focus on the solar and battery power systems that are managed by the Power Supply Unit board discussed last week.

It’s been a little over one week since ARISSat-1 was deployed from the International Space Station and it has been operating beautifully. Radio amateurs are submitting signal reports, telemetry and Slow-Scan TV (SSTV) pictures.

In the beginning, ARISSat-1 was to be SuitSat-2. It would have been deployed just like SuitSat-1: during an extra-vehicular activity (EVA) by pushing it away from the International Space Station (ISS).

Steve Bible provides an update of the successful deployment - despite a 'missing' antenna - of the ARISSat-1 satellite from in the International Space Station on Wednesday August 3.
