PicSat Status - Commissioning Continues, FM Transponder Test Success

PicSat was successfully launched on 12 January 2018 on the PSLV-C40 mission It is orbiting Earth at 505km altitude on a Sun synchronous orbit PicSat, a 3U CubeSat, was developed in a record time of 3 years by a small team of astrophysicists lead by Sylvestre Lacour (CNRS) at the LESIA laboratory / Paris Observatory / PSL in France

The main goal is to observe the southern hemisphere star Beta Pictoris continuously in order to capture any transit phenomena related to its planet that has been predicted to pass in front of the star by the summer of 2018 The commissioning phase is making good progress and the PicSat team is learning how to operate the satellite The main next step is to fully take control of the attitude and point in the desired direction

Thanks to the involvement and efforts of Sylvain Azarian (F4GKR) and the IARU, PicSat uses amateur bands to communicate:

Uplink:    145 910 MHz FM (when transponder is enabled) Downlink:  435 525 MHz FM voice, see web for data format

When not in science mode, PicSat has a transponder that will be made available for the amateur community: the timings will be announced A first transponder surprise test was done on 15 February from the Paris Observatory ground station in Meudon, France: https://www youtube com/watch?v=qQd0WEcoFgE&t=18s)

It was received by amateurs in Europe https://twitter com/supertrack_it/status/964267817095835648

During past weekend (17-18 February) the PicSat team had programmed downloads of House Keeping data from the payload over targeted areas across the planet Many amateurs received and send the data to the PicSat data base This has allowed for the first time to create a 24h monitoring of the temperature sensor readings, which are helpful diagnostics for the team showing the importance of this community effort: https://twitter com/IamPicSat/status/965982775718436864

Radio amateurs can register on the PicSat website to become involved and upload their data to the PicSat data base, where it will be visible for anyone to see and serve the PicSat team This will be even more important once observations of Beta Pictoris will start and a large stream of photometric data will be produced to monitor the brightness of the star and create the real time light curve

The PicSat team is most grateful for all the positive collaboration, feedback and help to date and looks forward to continue and strengthen this connection

Updates to AMSAT-NA TLE Distribution for 2-22-2018

Nico Janssen, PA0DLO, noted that 18th Space Control Squadron has swapped the satellite names associated with object 41845 (was CAS-2T) and another object 41847 Therefore CAS-2T is now object 41847 Nico's detailed doppler measurements confirm that CAS-2T is in fact object 41847 (Note: the payloads CAS-2T and KS-1Q still remain attached to the CZ 11 fourth stage ) Thanks Nico, good catch!

The PICSAT team and Albert Van Duersen indicate that a better set of TLEs for PICSAT is now object 43132 Nico Janssen has also noted that the best TLE set for PICSAT has been unstable since November 14th of last year   Nico says that now object 43132 and even object 43133 are better matches for PICSAT than object 43131 Therefore, we will use object 43132 for PICSAT for now   The problem is the closeness of objects 43131, 43132 and 43133 Nico says he will continue to monitor these objects as they slowly separate over time More later

Why is there so much TLE confusion when new Cubesats are launched?

AMSAT Orbital Elements Manager, Ray Hoad, WA5QGD provided some answers to frequently asked questions regarding every time a CubeSat gets launched, there is some confusion on what TLEs should be used

This is the result of the process of launching a new amateur CubeSat with other CubeSats, often several dozen at a time We then start the process of determining which object in a “flock” of CubeSats is associated with a particular spacecraft

Pre-launch TLEs, that is calculation based on the expected orbit, are usually supplied by the launch provider Pre-launch TLEs are used until post-launch TLEs (for the group of objects that your satellite is in) are released from the US Department of Defense Joint Space Operations Center (JSpOC) based on observations made with cameras and radars

There is a a 5 to 10 day period of tracking a group of CubeSats until they separate enough to isolate the one of interest By observing the Doppler shift on transmissions from a particular satellite against the calculated Doppler shift from all candi- date object TLEs, we can positively associate an object with a particular satellite In the case of AMSAT satellites, we then advise JSpOC which object number is “ours”

Finally, an individual satellite and its associated TLEs are determined and we settle down to an single, accurate, reliable set of TLEs … and all the other “best guesses” go away, although they may be still floating around on the Internet But, there are so many variables – did you launch on time, did you get released on time, has the group your CubeSat is in separated enough to identify your satellite, etc that the process that can be both confusing and annoying at the same time

AMSAT strives to minimize confusion when distributing TLEs Dummy object numbers are used for pre-launch TLEs since final object numbers cannot be assigned yet Immediately post launch we may post candidate objects with generic names like “OBJECT C” Finally, when positive association between an object number and a spacecraft is made, we will use the common name of the satellite We always recommend using TLEs from the Keps mail- ing list or the current bulletin or bare elements from the AMSAT web site

Canadian University Design Challenge for “Selfie-Sat”

On February 19, 2018 the Canadian Satellite Design Challenge announced a competition for a 3U Cubesat “Selfie-Sat” to be designed and built by Canadian university students

A snapshot of the Selfie-Sat mission:

1) amateur radio stations contact the university-built cubesat and    send a command for it to take a photo from space The photo is    then down-linked to the station, along with photos and stories    from Canada

2) The Selfie-Sat mission will be designed so that amateur radio    operators will be able to contact it as it passes overhead    During the contact, the radio operator will be able to send a    command for the satellite to take a “Space-Selfie” photo over    the region

3) The photo will be immediately transmitted to the ground, along    with Canadian stories for students of all ages, as well as other    scenic photos and descriptions of Canada

“We envision radio amateur operators setting up their equipment at science centres or even schools,” said Larry Reeves, Canadian Satel- lite Design Challenge Management Society President, “and having a public or school event for the pass We believe this mission will have outstanding educational benefits for students, and for promoting Canadian science, technology, and culture ”

First Citizen Science Workshop Measuring Effects of the Solar Eclipse

This past August, the United States was witness to one of the most beautiful and significant astronomical events in human history – a total solar eclipse that travelled across the country from Oregon to South Carolina

In addition to its visual beauty, this eclipse also had profound effects on the ionosphere, an electrically charged portion of the upper atmosphere that affects radio communications and navigation systems These ionospheric effects piqued the interest of scientists and amateur radio operators across the country They conducted one of the largest citizen science experiments in space science, an international ham radio operating event specifically for studying the eclipse Many of these scientists and hams will be gathering for the Ham Radio Science Citizen Investigation (HamSCI, http://hamsci org) workshop

The event will be held at the New Jersey Institute of Technology in Newark, NJ this Friday and Saturday (February 23-24, 2018) to share their observations and findings The program begins each day at 9AM at the Campus Center

Presentations by scientists and ham radio operators from the New Jersey Institute of Technology, the Johns Hopkins University Applied Physics Laboratory, NASA Marshall Space Flight Center, the Massachusetts Institute of Technology Haystack Observatory will highlight the program

All interested are welcome to attend the workshop For more information and registration, please visit http://hamsci org/hamsci2018

This HamSCI 2018 workshop is organized by Dr Nathaniel Frissell and is hosted by the New Jersey Institute of Technology Center for Solar-Terrestrial Research

Bittern DX Educational Outreach Project in the UK

AMSAT-UK shared a link from an article posted on England's North Norfolk news reporting on the success of Bittern DX’s educational outreach project with the Girl Guides

http://tinyurl com/ANS-056-GirlGuides

Eight members of a north Norfolk-based amateur radio group have been teaching girl guides how to contact colleagues around the world as part of Thinking on The Air Day

The team from Bittern DX’s educational outreach project made the journey to the village hall in Saham Toney, near Swaffham, to speak to about 60 rainbows, brownies, guides and their adult leaders

Thinking on the Air Day is an opportunity for the members of girlguiding from the youngest rainbow to the oldest trefoil guild member to talk to other members of the World Association of Girl Guides and Girl Scouts via amateur radio

On this day each year members remember the founders of the movement and take part in various activities to think about their sisters throughout the world

The girl guides were given the chance to find a transmitter 50 yards away, shown how the Morse code works, and they all keyed their name correctly, earning a certificate

They were then allowed to talk on air to each other using handsets before being introduced to VHF working with each participant correctly conducting a meaningful conservation with a club member outside on a handheld

One brownie had a short conversation with an amateur in Germany

Next they were shown the principles and techniques behind satellite working with three conversations conducted

Peter Stainton, publicity officer for the Bittern DX, said: “Club members found it very rewarding to see the young people take part in our hobby

“One brownie said it had blown her mind away to see what we could do But as a counterbalance, when being told how we could talk around the world and beyond, one commented ‘I just use Skype’ ”

The group’s outreach project is aimed at bringing an amateur radio experience to the general public and was given a boost last year with a grant of almost £10,000 from the National  Lottery’s Awards for All fund for new club equipment

The group also received money from the Radio Society of Great Britain Legacy Fund (RSGB) to help buy a trailer and new generator
