Consumer Grade Smartphone satellites go into orbit and send back pictures to amateur radio operators and NASA

For about one week, engineers at NASA’s Ames Research Center, Moffett Field, Calif., and amateur radio operators around the world collaborated to reconstruct an image of Earth sent to them from three smartphones in orbit. The joint effort was part of NASA’s nanosatellite mission, called PhoneSat, which launched on Sunday, April 21, 2013 aboard the Antares rocket from NASA’s Wallops Island Flight Facility in Virginia.

Although the ultimate goal of the PhoneSat mission was to determine whether a consumer-grade smartphone can be used as the main flight avionics for a satellite in space, the three miniature satellites (named Alexander, Graham and Bell) also took pictures of Earth and transmitted these “image-data packets” to multiple ground stations on Earth.

Although the ultimate goal of the PhoneSat mission was to determine whether a consumer-grade smartphone can be used as the main flight avionics for a satellite in space, the three miniature satellites used their smartphone cameras to take pictures of Earth and transmitted these “image-data packets” to multiple ground stations. Every packet held a small piece of “the big picture.” As the data became available, the PhoneSat Team and multiple amateur ham radio operators, who call themselves “hams,” pieced together a high-resolution photograph from the tiny data packets.

“During the short time the spacecraft were in orbit, we were able to demonstrate the smartphones’ ability to act as satellites in the space environment,” said Bruce Yost, the program manager for NASA’s Small Satellite Technology Program. “The PhoneSat project also provided an opportunity for NASA to collaborate with its space enthusiasts. Amateur radio operators from every continent but Antarctica contributed in capturing the data packets we needed to piece together the smartphones’ image of Earth from space.”

As part of their preparation for space, the smartphones were outfitted with a low-powered transmitter operating in the amateur radio band. They sent the image information to awaiting hams who worked with the Ames engineers to stitch together multiple, tiny images to restore the complete Earth view.

Piecing together the photo was a very successful collaboration between NASA’s PhoneSat team and volunteer amateur ham radio operators around the world. NASA researchers and hams working together was an excellent example of Citizen Science, or crowd-sourced science, which is scientific research conducted, in whole or in part, by amateur or nonprofessional scientists. On the second day of the mission, the Ames team had received over 200 packets from amateur radio operators.

“Three days into the mission we already had received more than 300 data packets,” said Alberto Guillen Salas, an engineer at Ames and a member of the PhoneSat team. “About 200 of the data packets were contributed by the global community and the remaining packets were received from members of our team with the help of the Ames Amateur Radio Club station, NA6MF.”

The mission successfully ended Saturday, April 27, 2013, after predicted atmospheric drag caused the PhoneSats to re-enter Earth’s atmosphere and burn up.
