Jan Stupl provides an update on PhoneSat 2.4 which was part of  the ORS3 / Elana 4 launch from the Wallops Flight Facility on November 19, 2013.

Minotaur-1 Launch from Wallops Flight Facility

Minotaur-1 Launch from Wallops Flight Facility

By now there are TLEs at space-track for all 29 objects of that launch (NORAD ID 39380 – 39409), but only five of them have been identified on space-track.

The PhoneSat team thinks that 39381 is theirs, but 39402, 39400 and 39397 are also (less likely) possibilities. Because the satellites are still close, using the radio beacon for identification is somewhat ambiguous. Getting more observations would be very helpful for everybody on that launch.

You find all information about the 437.425 MHz PhoneSat 2.4 on the phonesat.org website and people can submit received packets as well, and comment which TLE they used. The latter is obviously important to gain confidence on the assigned TLEs.

PhoneSat: “Crowd-sourced science” via ham radio

Phonesat ConstructionEDN magazine interviews Jasper Wolfe about the new Phonesats to be launched this year which will carry amateur radio payloads.

The Phonesats were developed by young engineers (average age 23) at the NASA-Ames Research Center.

The EDN article by Steve Taranovich says:

Wolfe told us that NASA’s next generation PhoneSat satellites to be launched on November 6 and December 6, will emit packets over the amateur radio band at 437.425 MHz. Satellites transmit using AFSK (1200 bps) modulation, AX.25 packet coding and have vertical linear polarization. As in the first launch, hence the term “Crowd-sourced science” coined by mentor Jim Cockrell.

The two PhoneSat 2 and 3 satellites will transmit with a periodicity of respectively 28 seconds and 30 seconds. The PhoneSat 2.0 beta satellite, Alexander, transmit with a periodicity of 25 seconds. One satellite will be up there for two years and the other for three months.

Antares Rocket Tuesday, April 16, 2013

Three PhoneSat CubeSats with amateur radio payloads were launched on an Orbital Sciences Corporation Antares(TM) rocket from NASA’s Wallops Flight Facility (WFF) in eastern Virginia on Sunday, April 21.

The three PhoneSats carry amateur radio payloads on 437.425 MHz, each transmits at intervals so all three are receivable during a pass. Roland Zurmely PY4ZBZ received them on the second orbit on April 21 at 22:52 UT, see http://www.qsl.net/py4zbz/phs.htm and Mike Rupprecht DK3WN reported receiving all three on Monday April 22, see http://www.dk3wn.info/p/?p=32755

The callsign of all three satellites is KJ6KRW and they transmit using AFSK (1200 bps) modulation, AX.25 packet coding. The two PhoneSat 1.0 satellites, Graham and Bell, transmit with a periodicity of respectively 28 seconds and 30 seconds. The PhoneSat 2.0 beta satellite, Alexandre, transmits with a periodicity of 25 seconds.

Watch PhoneSat: Small Satellites Use Smart Phones For Brains

PhoneSat was chosen as one of the winners in the Aerospace category for the Popular Science magazine “Best of What’s New 2012″ awards. The PhoneSat is a technology demonstration mission consisting of three 1U CubeSats intended to prove that a smartphone can be used to perform many of the functions required of a spacecraft bus.

The satellite is built around the Nexus smartphone which will be running the Android operating system and will be enclosed in a standard 1U CubeSat structure. The main function of the phone is to act as the Onboard Computer, but the mission will also utilize the phone’s SD card for data storage, 5MP camera for Earth Observation, and 3-axis accelerometer and 3-axis magnetometer for attitude determination.

One of the nanosatellites, powered by the HTC Nexus One smartphone, will send back pictures of Earth. The other two, running on the Samsung Nexus S, will have two-way S-band radio allowing them to be controlled from Earth.

The satellites have no solar cells and operate on battery only so will only have a lifetime of about a week,

An updated website with telemetry info is now available.

The Antares launch includes the commercial DOVE-1 satellite, a technology development experiment. The satellite had requested IARU coordination for a 1 watt transmitter on 145.825 MHz to downlink a 1200 baud AFSK AX.25 beacon with telemetry and health data. The AMSAT News Service reported in ANS-027 that according to the IARU DOVE-1 will no longer be using frequencies in the amateur radio bands.

It appears the USA FCC granted the experimental callsign WF9XKA for the use by Dove 1, it is believed it may use a downlink on 2420 MHz. Search for Cosmogia at https://apps.fcc.gov/oetcf/els/reports/GenericSearch.cfm

PhoneSat Stand at 2012 Bay Area Maker Faire

PhoneSat Stand at 2012 Bay Area Maker Faire

In Aviation Week Michael Mecham reports the world’s university students come to work at Ames, which takes a leadership role in several areas for NASA, including smallsats, astrobiology and super computing.

“We have lots of internationals,” says NASA Ames Research Director Peter Wooden, referring to his young talent pool. “This is where opportunity comes for them. The ideas are what matters. It’s not your nationality.”

That opportunity arises because they stand such a good chance of getting their hands on a project like the PhoneSat-1/-2, a pair of cubesat-sized (10 cm square) nanosats due for launch Apr. 17 out of Wallops Island on an Antares, the new commercial launcher from Orbital Sciences.

The big deal about the PhoneSats is that they use the computing guts of smart phones bought at a big box store. They’re early tests of a low-risk, low-cost approach to satellite manufacturing that emphasizes the exploitation of off-the-shelf materials without a lot of fuss about whether they are “space proven.”

Worden says the aim is to arrive at the day when anyone with an idea can find a way onto a satellite by developing a “satellite app.”

Among the amateur radio CubeSats on the launch are three Phonesats which will all carry Google Nexus smartphones similar to the pioneering UK smartphone satellite STRaND-1 that was launched in February. There will be two PhoneSat 1.0’s and one PhoneSat 2.0 on the launch.

PhoneSat 1.0 cost about $3500 and is built around the Nexus One smartphone, it operates on battery power only with a mission lifetime of approx 1 week.

PhoneSat 2.0 is more expensive at $8000. It is built around the Nexus S smartphone and has solar panels on each face and a mission lifetime until de-orbit of approximately 2 weeks.

The IARU amateur satellite frequency coordination panel have coordinated frequencies of 437.425 MHz and 2401.2-2431.2MHz for the PhoneSats.

Also on the launch is the Dove-1 CubeSat. The Antares-110 launcher is expected to deploy the satellites into a 250 km 51.6° inclination orbit.
