The judges from the UK Space Agency, Blue Peter and ESA together chose their two favorites in each of the three age groups of 6–8, 9–11 and 12–15 years. Important considerations for deciding on the final six were how a design would look as a patch, the colors used and whether the children drew everything on their own. The selection of the winning design out of the six came down to Tim himself.

The mission name Principia comes from Isaac Newton’s world-changing three-part text on physics, Naturalis Principia Mathematica, describing the principal laws of motion and gravity.

The winning entry was by 13-year-old Troy who used an apple to signify Newton’s law of gravity. Fittingly a stylized International Space Station (ISS) glints in the apple. The Soyuz rocket taking Tim into space flies over the UK as the colors of the Union Flag run along the border.

In September Tim Peake KG5BVI learned how to use the Ericsson 144 MHz handheld radio which is installed in the Columbus module of the ISS. On September 18 Tim said “Will be great to chat with schools next year from space using this ham radio on board the ISS.”

Pocket Spacecraft

The plan is that a 3U CubeSat will carry Pocket Spacecraft known as ‘Scouts’ to the Moon. A ‘Scout’ is a disk with flexible electronics, smaller than a CD, containing a transceiver, antenna and solar cells. The CubeSat should first release a batch of the wafer thin Scout satellites into Earth orbit and then deploy another batch of the Scout satellites into Lunar orbit.

It is understood the mission plans to use the 435 MHz and 2400 MHz bands.

Goonhilly Earth Station (GES) Ltd are transforming the BT satellite communications site at Goonhilly into a new Space Science centre.

The Goonhilly Satellite Earth Station is located on the Lizard Peninsula in Cornwall. It’s famous for many reasons, but perhaps most notably, for receiving, the first ever trans-Atlantic satellite TV images, broadcast by Telstar, on July 11, 1962. The impressive 25.9m dish called Arthur was used for that historic event.

The Register has published an article by journalist SA Mathieson following a recent visit to the site. This included seeing the AMSAT-UK ground station used to track the satellites FUNcube-1 and UKube-1 which both carry educational payloads developed by radio amateurs from the voluntary satellite organisations AMSAT-UK and AMSAT-NL. The station comprises an Asus PC with FUNcube Dongle Pro+ Software Defined Radio (SDR) and a turnstile (crossed dipoles) antenna.

SA Mathieson also visited another recent addition to the site, the radome used by the imaging start-up Planet Labs Inc to communicate with its constellation of  “Dove” CubeSats.

SpinSat was launched to the International Space Station (ISS) on September 21 with the deployment planned to take place from the Japanese Experiment Module (JEM) in the Fall.

Masahiro Arai JN1GKZ has reported that SpinSat is expected to be deployed, using the Cyclops deployment system, from the airlock of the JEM on Friday, November 28. Preparation work for the deployment should take place on November 26 and 27.

Developed by the Naval Research Laboratory (NRL) SpinSat is a 56 cm sphere weighing 57 kg that has 12 Electronically-controlled Solid Propellant (ESP) thrusters spread in pairs throughout the surface of the satellite. They will be fired in pairs to spin the spacecraft. With just primary batteries and only 4.8 grams of fuel this phase may last between three to six months.

The spacecraft will be used to calibrate the space surveillance network. Lasers will be fired at SpinSat from the ground, the light reflected back will be measured to determine where in time and space the satellite is passing overhead. SpinSat will also model the density of the atmosphere.

The IARU Satellite Frequency Coordination Panel report that SpinSat carries a 2 watt RF output 9600 bps AX.25 packet radio store and forward system on 437.230 MHz.

Happy Birthday, $50SAT/MO-76!

Yaesu handheld and $50SAT 1.5U PocketQube

Yaesu handheld and $50SAT 1.5U PocketQube

Friday, November 21, 2014 marked the one year anniversary of the launch of $50SAT/MO-76 PocketQube satellite.

Michael Kirkhart KD8QBA writes:

Our little creation was launched from Dombarovsky Air Base in Russia at 07:01 UT (which was 2:01 AM here in EN82 land) as one of 33 satellites aboard a Dnepr rocket. It was first heard by Jan, PE0SAT, at 08:46 UT, and by Stuart GW7HPW at 09:17 UT, and has been operating continuously ever since!

The $50SAT/MO-76 Dropbox now contains a snapshot of all the telemetry gathered from launch day through November 21, 2014.
https://www.dropbox.com/sh/l3919wtfiywk2gf/AAC0dF52-SAKbci7gK6iELaja/Telemetry-analysis/2014-11-21

$50SAT/MO-76 continues to operate normally, but the battery capacity has been slowly dropping to the point where it barely registers above 3500 mV when passing over EN82 land during daytime (decending) passes. I have been able to capture telemetry while it passes over Anton’s (ZR6AIC) WebSDR station http://zr6aic.giga.co.za:8902/ which is located in South Africa. During ascending passes, which occur between 20:00 and 21:30 UT, $50SAT/MO-76 has just transitioned from being in sunlight to being in eclipse, and the battery voltage is between 3602 and 3642 mV.

Over the life of $50SAT/MO-76, we have observed the following:
The maximum battery voltage was 3824 mV, while the minimum was 3440 mV
The maximum PCB temperature was 25 degrees C, while the minimum was -29 degrees C
The maximum RFM22 temperature was 29 degrees C, while the minimum was -30 degrees C
The maximum MPPT (solar) power was 312.84 mW
The maximum idle (RFM22 off) current was 3 mA, while the minimum was 2 mA
The maximum receive mode current was 31 mA, while the minimum was 21 mA
The maximum transmit mode current was 88 mA, while the minimum was 77 mA

On December 4, 2013, the folks at NORAD and Celestrak (with help from Mike, DK3WN) were able to identify $50SAT/MO-76 as object 2013-066W. At this time, apogee was at 640 km, and perigee was 595 km. As of November 21, 2014, apogee is at 599 km, and perigee is at 565 km. This means the average altitude has decreased by about 36 km. A spreadsheet, along with a graph of the orbital data is available on the $50SAT/MO-76 Dropbox
https://www.dropbox.com/sh/l3919wtfiywk2gf/AADn6QqebB-_F7yKXc2RTaU0a/Orbit-analysis

While we did not have time to demonstrate this at the AMSAT-NA Space Symposium, we now have a working Arduino/RFM22 based groundstation. It utilizes a slightly modified version of the Sparkfun RFM22 Arduino shield https://www.sparkfun.com/products/11018 Additional information, including photos, marked up schematics, and the Arduino sketches, is available (guess where?) on the $50SAT/MO-76 Dropbox.
https://www.dropbox.com/sh/l3919wtfiywk2gf/AADw6hSSdaccILYdnpnBTUmta/Arduino-Groundstation

In addition to the original, receive-only sketch (S50SAT_receiver), there is a new version (S50SAT-Groundstation) which includes transmit capability, which supports all three open uplink commands. Both versions are capable of receiving all GFSK based packets, including the FEC packets.

I have successfully received $50SAT info and FEC packets from about 1200 km slant range with my groundstation using an Advanced Receiver Research P432VDG LNA http://advancedreceiver.com/page5.html with my homebrew 6 element WA5VJB yagi. The LNA is needed to improve the sensitivity of the RFM22, which is about -99 dBm. Since the RFM22 can only output 20 dBm (100 mW) and the minimum EIRP needed to uplink to $50SAT/MO-76 when it is directly overhead is about 36 dBm (4W), either a 16 dB gain antenna, an external linear amplifier, or both will be needed to successfully uplink.

Speaking of uplinking, no one has completed the $50SAT/MO-76 Uplink Challenge. This challenge is open to any licensed amateur radio operator, and the prize for successful completion is (drum roll…) a certificate of technical achievement, signed by all three of the $50SAT/MO-76 developers.

Our thanks to all who has supported us in this project, including all of you telemetry gathers. Please keep the telemetry coming!

$50SAT was a collaborative education project between Professor Bob Twiggs, KE6QMD, Morehead State University and three other radio amateurs, Howie DeFelice, AB2S, Michael Kirkhart, KD8QBA, and Stuart Robinson, GW7HPW. The transmitter power is just 100 mW on 437.505 MHz (+/-9 kHz Doppler shift) FM CW/RTTY. $50SAT uses the low cost Hope RFM22B single chip radio and PICAXE 40X2 processor.

Ham radio launches to deep space

ARTSAT2:DESPATCH Internal Structure

ARTSAT2:DESPATCH Internal Structure

ARTSAT2:DESPATCH is going to launch on a mission into deep space on November 30, 2014 carring a 7 watt CW transmitter on 437.325 MHz.

It will fly with the asteroid mission Hayabusa 2 and another amateur radio satellite Shin’en 2.

ARTSAT2:DESPATCH will have an elliptic orbit around the Sun and travel to a deep space orbit between Venus and Mars. Its inclination will be almost zero, which means Shin’en 2 will stay in the Earth’s equatorial plane. The distance from the Sun will be between 0.7 and 1.3 AU. An Astronomical Unit (AU) is 149,597,871 km.

ARTSAT2 DESPATCH Deep Space Sculpture

The team have released the following information:

1. Despatch CW Format is now available!

Yesterday, we opened a wiki which explains how to join the “Cooperative data reconstruction,” the main mission of Despatch.  In this wiki, you can find the CW format as well as how to report the data you received.
http://despatch.artsat.jp/en/Cooperative_Data_Reconstruction

2. Despatch Tracking page is opened!

Since Despatch is injected into an Earth escape trajectory, TLE is unavailable. Instead, we opened a web-page for the spacecraft tracking (both antenna-pointing and receiver-tuning).
http://api.artsat.jp/pass/

Please go to the page and enter your geographic location, and you will get nearby passes and a table with 1 minute steps that gives you AZ, EL, Freaquency, and so on. As the apparent movement and the change of the Doppler shift are slow, manual pointing of the antenna and tuning of the receiver every 10 minutes or so will do.

3. Reception Report page is opened!

We opened a web page in which you can report the data you received.
http://api.artsat.jp/report/

Thanks in advance and all the best,

OSCAR Locator App

OscarLocator-1Tom Doyle W9KE has developed a Windows satellite tracking App that reproduces the graphical display of the original cardboard OSCARLOCATOR .

Most tracking programs use an equirectangular projection which is by far the easiest to program and shows the entire Earth at once. A 3D model is often used which helps visualize orbits but does not show the entire Earth at the same time.

Tom remembers having an easier time visualizing the orbits back in the day (1970’s) when amateurs used cardboard OSCAR Locators with overlays. This Windows program lets you visualize orbits OSCAR Locator style.
