Delft University of Technology Delfi-PQ PocketQube Receives IARU Coordination

Delfi-PQ is an educational PocketQube mission designed by the MSc and BSc students at the Delft University of Technology in the Netherlands. The design of this spacecraft has been carried out as part of their curricula to acquire experience on the field. Students are involved on all the mission phases and they will also participate in operations.

The second goal of this mission is technology demonstration, being this spacecraft one of the smallest ever launched belonging to the PocketQube class with a size of 50x50x192 mm. It contains all the required systems to operate in space.

It is one of the first PocketQubes to be launched and it is the cornerstone for a series of PocketQubes from TU Delft with the aim to iteratively advance the platform to enable ambitious scientific objectives with networks of PocketQubes in the future.

Delfi-PQ mainly focusses to demonstrate a reliable core system (comprising a power system, a communication system, an attitude control system and an on-board computer). Furthermore, it will host a few small-scale experiments which can be used for technology research.

These experiments are related to future propulsion, more advanced attitude control, navigation, thermal analysis and control. The orbital life time of Delfi-PQ is currently foreseen to be very short (only up to 150 days due to the low orbit of deployment). This will ensure the spacecraft cannot contribute to the space debris problem and also it will occupy its assigned frequency band for a very short time, preventing spectrum pollution.

The demonstration of the core spacecraft and its experiments is expected to take all the mission time, till deployment. The communi- cation system, in particular, will be tested and the support of amateurs will also be important.

AX.25 will be used worldwide to deliver telemetry. The protocol was selected due to the widespread community around the world that make already use of such a standard. A mode using advanced communication protocol, using forward error correction, will be tested upon command (and so receivable over Europe). This new protocol is decoded by the provided decoding software. The decoding software will enable radio amateurs to help estimating the performance of the receiver in different conditions with statistics transmitted back to a central server

In order to provide a return favor to the radio amateur community for the use of the frequency bands, this mission will publish all the instructions for satellite reception and telemetry decoding. A decoding application will also be provided to radio-amateurs around the world before launch to allow easy decoding with standard hardware. This application will also be used to submit the received frames to a central repository. The contribution from radio amateurs in receiving the data will greatly enhance the mission.

To make it more exciting to participating radio amateurs, several challenges will be organized. Examples of challenges are thereception of the first and the last frame. In particular, the first received frame will be important for the team to assess the status of health of the spacecraft. The submitter will receive a prize for it.

Since the satellite will be deployed to only 350 km and the foreseen operational lifetime is equal to the orbital life time, it will be very interesting to monitor its deorbiting process. Next to this, the number of received frames and the global distribution will also lead to the definition of several challenges. All challenges will have some small prize and achievement certificate associated with it.

A UHF downlink on 436.650 MHz has been coordinated by the IARU. The transmission protocol will be GMSK at up to 19k2 bps. Planned for a launch on a Vector rocket from Kodiak Alaska in August 2018 with other PocketQubes.

What is a Lilac Doing in Space?

Student Built LilacSat-1's Success with an Amateur Radio

Mission LilacSat-1 accomplished, according to the reports from the students at the Harbin Institute of Technology.

The student built LilacSat-1 carries an amateur radio 145/436 MHz FM to Codec2-BPSK digital voice transponder, APRS Digipeater and camera.

The satellite was developed at the Harbin Institute of Technology and is part of the QB50 mission which aims to study the lower thermosphere. It was deployed from the International Space Station at 0835 GMT on Thursday, May 25, 2017.

Shortly after deployment LilacSat-1 took a picture of the solar panels on the ISS. The image was downloaded by the students on 436.510 MHz +/- 10 kHz Doppler Shift using 9600 bps BPSK.

The FM to Codec2-BPSK transponder was activated late afternoon GMT on Thursday, May 25:

FM Uplink 145.985 MHz with 67 Hz CTCSS (PL Tone) Codec2 9600 bps BPSK Downlink 436.510 MHz

The first contact using the Codec2 transponder took place on May 31 between Mike Rupprecht DK3WN and John Grant GI7UGV http://www.dk3wn.info/p/?p=79889

LilacSat-1 radio information is at https://tinyurl.com/ANS105-LilacSatRadioInfo

AMSAT Plans Hamvention Rollout for 2018 "Getting Started" Satellite Book

Gould Smith's book, "Getting Started With Amateur Satellites", is being updated to tell you all about how you can get ready to operate through the Fox-1 satellites launching later this year. Additional chapters in the book tell you about tracking software, orbital mechanics, antennas, radios, Doppler tuning, and operating techniques. Chapters are also being added to tell you about the new satellites (and there are many)soon becoming available for amateur radio.

Going beyond brief descriptions in hamfest flyers, this book will provide a complete reference for new satellite users to assemble a basic station and to make your first satellite contacts. Also this book you will teach you how to incrementally upgrade your initial FM satellite station, time and budget permitting, to include automated tracking as well as operating through the CW/SSB linear passband satellites.

A companion Fox Operating Guide reference sheet is ready for release at Hamvention 2018. This will be made available for the AMSAT Ambassadors (formerly FieldOps) team for distribution at hamfests and satellite operating demonstrations.

Watch for the 2018 "Getting Started With Amateur Satellites" book and reference sheet at the AMSAT booth at the Hamvention. The book will also be available in the AMSAT Store shortly after Hamvention: https://www.amsat.org/shop/

MiniTiouner-Express Receiver Assembly for ISS HamTV 2.395 GHz Downlink

A receiver suitable for the ARISS/HamTV 2.395 GHz DVB-S downlink from the ISS is now available for purchase. The MiniTiouner-Express receiver/tuner/analyzer assembly is a completely assembled and tested unit contained in a small aluminum enclosure about the size of a 2 stack deck of cards.

The DATV-Express group created the design, construction and sale of the Minitiouner-Express receiver. It is used with the free soft- ware by Jean Pierre Courjaud F6DZP. The unit connects between an antenna(s) and a PC computer USB2 or USB3 port using the Windows 7, 8 or 10 operating system. It receives DVB-S/S2 144MHz to 2420MHz digital television signals for symbol rates between 100K and 10M symbols/sec when used with the F6DZP MiniTioune software.

In operation, the computer monitor displays the received video and graphic landing dot constellation to show the incoming signal level, quality, FEC, MER and setup information.

The MiniTiouner-Express Receiver/Analyzer unit can be ordered from the http://www.datv-express.com/ website. You need to first logon to the website (or first register if you are a new user). Use the PURCHASE A PRODUCT tab to order the product via PayPal.

The price for the MiniTiouner-Express unit is US$75 + shipping Shipping for USA is US$7.00 Shipping to the European Union is US$24.00 including the VAT Shipping anywhere international is US$35.00 Although initial stock has been depleted more units are on the way.

The MiniTiouner-Express User Guide (draft13) can be downloaded from http://www.datv-express.com/CustomPage/Downloads

Information about the ARISS HamTV project can be found at: http://www.ariss-eu.org/columbus/ham-video

The HamTV downlink from the ISS has recently only been active for selected school contacts. HamTV often transmits a "blank signal" useful for receiver and antenna testing when not in use for school contacts.
