FUNcube-1 (AO-73) is again transmitting telemetry. A restart took place during the 0930 UT pass over Europe.

The CubeSat had stopped transmitting at around 2018 UT on Wednesday, April 15.

The team is still investigating the situation, but have concluded from earlier telemetry analysis that it was safe to switch back to nominal operations.

During the 0930 UT pass over The Netherlands, Wouter PA3WEG commanded it back to nominal mode with full automatic mode switching.

At this time, there is no reason to believe this event was dangerous to the spacecraft, all systems were nominal and the battery is nearly full.

Many thanks for all the reports that the team have received.

AESP-14 CubeSat

The Japanese Space Agency, JAXA, have released a video showing the deployment of the Brazilian amateur radio satellite AESP-14 from the International Space Station (ISS).

The AESP-14 is a 1U CubeSat developed by undergraduate and graduate engineering students at the Technology Institute of Aeronautics (ITA) in Brazil. The satellite’s primary mission is to test the various subsystems in the space environment.

The satellite was sent to the ISS as cargo on the SpaceX Falcon 9 mission CRS-5. Launch had been scheduled for December 16, 2014 but was postponed three times and it wasn’t until January 10, 2015 that the launch eventually took place. AESP-14 then awaited deployment from the ISS by the JEM Small Satellite Orbital Deployer (J-SSOD) which is in the Japanese Experimental Module, Kibo.

The deployment took place around 1250 UT on Thursday, February 5. The AESP-14 telemetry beacon had a power output of 500 mW and used AX.25 with 9600 bps GMSK modulation (G3RUH standard) on 437.600 MHz. It should have started transmitting 30 minutes after deployment but as of March 30 nothing had been heard. It may be the battery did not survive several months without being recharged or the antenna may have failed to deploy.

FUNcube-1 Solar eclipse update

As expected, FUNcube-1 (AO-73) entered the shadow of the moon around 1000 UT on Friday, March 20, 2015.

Solar panel currents dropped to almost zeroThis is what happened to the solar panel currents, they dropped to almost zero.

This what we usually see from our Whole Orbit Data telemetry

This is what we usually see from our Whole Orbit Data telemetry. Normally the CubeSat is in the sun for 60 minutes and in eclipse for around 30 minutes…but not this morning!

ITU: Small satellite communication systems regulatory requirements

2011-ITU-logo-officialThe ARRL reports International Amateur Radio Union (IARU) representatives were in Prague earlier this month to join discussions on the regulatory aspects of orbits and spectrum usage for nanosatellites and picosatellites.

On hand for the International Telecommunication Union (ITU) Symposium and Workshop March 2-4 were IARU Vice President Ole Garpestad, LA2RR, and former IARU Region 1 President Hans Blondeel Timmerman, PB2T. In particular, discussions centered on the application of the ITU Radio Regulations. The symposium concluded with the unanimous endorsement of the “Prague Declaration on Small Satellite Regulation and Communication Systems.”

“The symposium provided a unique opportunity for experts to examine the procedures for notifying space networks and consider possible modifications to enable the deployment and operation of small satellites,” said ITU Secretary-General Houlin Zhao. “‘The Prague Declaration’ represents an important step in this direction.”

More than 160 participants from some 40 countries attended the symposium. The gathering is being considered an important step in preparing for the 2015 World Radiocommunication Conference (WRC-15) in Geneva November 2-27.

Delegates discussed challenges facing small satellite development, including aspects related to national and international legal and regulatory issues, frequency management, and radiocommunication standardization. Participants reiterated the need to ensure the long-term sustainability of small satellites in outer space. They stressed the importance of implementing national regulatory frameworks that clearly define the rights and obligations of all stakeholders, in conformance with international laws, regulations, and procedures established by the UN General Assembly, the United Nations Committee on the Peaceful Uses of Outer Space, and the and ITU.

These regulatory issues relate to the registration of objects launched into outer space, frequency coordination, and the registration of satellite networks, as well as compliance with the space debris mitigation guidelines.

ITU Radiocommunication Bureau Director François Rancy, said the ITU, in partnership with key players, including academe, “is addressing newly emerging requirements by various industry sectors to place small communication satellite systems in orbit. “We are examining the regulatory aspects of the use of radio frequency spectrum and satellite orbits to facilitate the launch and operation of a new generation of small satellites,” he said.

The symposium was organized by ITU in cooperation with ITU Academia Member, the Czech Technical University’s Faculty of Electrical Engineering (CTU FEE).

Women, STEM and Amateur Radio

Bob McGwier N4HY writing code for the amateur satellite P3E

Bob McGwier N4HY writing code for the amateur satellite P3E

Bob McGwier, N4HY shares his views about Women in Science, Technoloy, Engineering, Math and Amateur Radio.

Bob, a former AMSAT director and vice president for engineering, is Director of Research, Hume Center and Research Professor of Electrical and Computer Engineering at Virginia Tech.

At Virginia Tech, where I lead the work in a large research center, I have several female graduate students in Electrical and Computer Engineering (ECE). I had one female graduate student in Aerospace and Ocean Engineering (master’s degree). I have multiple female undergraduate research assistants including the most amazing kid who came with many RF engineering projects in her experience base, an engineering notebook, and a daddy who couldn’t talk her into amateur radio and who told her she was on her own after sophomore year (she’s a second semester freshman). I have a female executive assistant, a female project manager, a female program manager for research, and a female program manager for education.

They are an incredibly diverse group of talented people that it is my honor and privilege to work with. Yet, they all have one thing in common that I wish to share. They are all licensed radio amateurs.

I am the faculty adviser at Virginia Tech’s Amateur Radio Association. I am the architect and designer and the principal investigator on the new Virginia Tech Satellite Ground Station which should go into operation in April. I have four graduate students who are doing thesis projects, class projects, and more involving this facility. A young member of our engineering staff, also a ham, is the actual lead system engineer on this project. At the all volunteer meetings for construction, operation of amateur radio satellites (such as QB50) over half the people coming are women and all are working on their ham licenses so they can operate the amateur radio spacecraft. Do you think there might be a connection, a correlation, and maybe even an agenda?

My mother put amateur radio in front of me in a very positive way and she was a super strong principled woman. She stood in front of racism in a county that had a KKK wizard as sheriff and ran the campaign committee with her best friend for the sheriff that defeated him. She was a feminist. She was a feminist in the mode of: you, as an individual, must treat everyone the same way, not equal outcomes but with equal care and intent, and provide for equal opportunity and then they are on their own.

My goodness! She was and is an amazing woman and she is so brilliant. She left school, married my father and had me. In my center, no one is forced to be a ham. I don’t give the exams, I only lead by example, and explain how amateur radio has impacted me. I leave it there. The results speak for themselves.

I am determined to have the women around me have NO ceiling on their achievement where I can remove the ceiling without disadvantaging anyone else. I encourage them to reach for the stars. I push them hard in their research and at work. I expect no less of them than I do any other. My mother pushed me hard, showed me the value of work and discipline and made me work to pay my way. I will push them. I believe I am showing that the numbers in engineering and sciences are a product of socialization and not capability.

In four short years, I give you the above. I must be developing a reputation. My center director and I are getting almost all the top talent coming into graduate school in ECE (male and female) as our graduate students. I am getting most of the female graduate students and I am DEFINITELY getting all of them that are in the top ten (say) entrants. I owe this to my mother Ann Terry for all she did for me, literally saving me from self-destruction. I owe it to the many women I have seen with my own two eyes who are smart beyond compare and are vectored down roads that might not be of their choosing because they don’t see opportunity, or the value, or life affirming virtues of this path. I am appalled and will fight back. They can choose what they will, but they will be shown the value.

I have a mentor who many of you know. It is Tom Clark, K3IO. He was doing what I am doing now years before and was an example I have always tried to emulate in this regard.

Finally: On the undergraduate student, she took and passed tech and general in one night. She went home and proudly showed dad who went “Yeah but I have an extra class”….. She pursed her lips and looked at me as she told this and I said: “The extra exam is given every month at VTARA this Spring, but the work I am giving you and your grades are the top priority”. NOTHING stands in the way of women doing math, science and engineering except the roadblocks we place in front of them.

What are you doing to your daughters, sisters, female friends that, even without intent, discourages them so that a single man on a mission can draw this much out of the crowd without a single word of advertising, self promotion, and just word of mouth really telling that we are here. Introspection and mindfulness are all I am asking for.

I almost forgot to mention, my very first graduate student was a female and a ham and got her Master’s degree in Mathematics from me at Auburn University in 1986. Lynne now has her doctorate in stochastic processes and statistics from UNC and is on the faculty at Georgia. Her father, Eddie, is also a ham and an example of the kind of encouragement that EVERY father of a daughter should provide. I haven’t embarrassed them by tagging them, but they are in my fondest memories.

The student built GRIFEX CubeSat was launched, along with FIREBIRD-2,  ExoCube and NASA’s SMAP, on Saturday, January 31 on a Delta 2 rocket from the Vandenberg Air Force Base. The first reception report of the spacecraft’s 437.485 MHz 9600 bps AX.25 GMSK signal was from Jan van Gils PE0SAT in the Netherlands.

James Cutler KF6RFX of the Michigan Exploration Laboratory has provided this update on the first 9 days after launch.

On the behalf of the GRIFEX team, thanks for all your help in tracking GRIFEX. The students working on this mission have had blast working with HAMS all over the world.

It seems that everyday someone new engages with the students and lets them know they heard GRIFEX.  We’ll be making QSL cards shortly so let us know if you need one.

GRIFEX so far is doing great.  We’re in a sun-sync terminator orbit, so we see the sun all the time.  We have plenty of power but we are fairly warm. We have active magnetic control as well that we may try later on so that our colleagues down under can get some better signal reception!

We had about five new students get their HAM license in support of this launch. Anywhere from 5-10 students get their license per year in the lab.

Thanks for your support!

UWE-3: Preliminary continuation of operations

UWE-3 LogoSince the temporary end of UWE-3 operations two months ago we received great support from the HAM community all over the world observing the health state of our satellite. For this reason and this reason alone we can say today UWE-3 is still experiencing a very good health state with fully charge batteries in a safe temperature area.

Now, UWE-3 will be temporary operated during the next days and weeks, which will presumably also involve, at times, temporary changes of frequency between 437.385000 MHz and 436.395200 MHz.

We would especially appreciate the support of the HAM community during this period and we would like to thank you very much for your helpful support!

Yours sincerely,

UWE-3 Team
