The Polish amateur radio satellite PW-SAT built by students at the Warsaw University of Technology was featured on BRITE TV.

The Internet TV channel BRITE TV, covers the construction of the first Polish scientific satellites BRITE-PL 1 – Lem and BRITE-PL 2 – Hevelius which will be part of the BRITE constellation. Sometimes the TV channel covers other topics related to space technology.

Episode 14 talks about the CubeSat PW-SAT, built by students of Warsaw University of Technology working with the Space Research Centre PAS, due to be launched on Vega at the end of January.

PW-SAT carries a single channel transponder that will operate in a similar way to the amateur satellite AO-16. The uplink on 435.020 MHz will be FM and the downlink on 145.900 MHz will use the BPSK telemetry beacon transmitter to produce Double Sideband (DSB) that can be received on an SSB radio.

AMSAT-India 435/145 MHz Linear Transponder

At Hamfest India (HFI) 2011, held in Kochi Dec 10-11, a presentation was given on a new Indian linear transponder and a CubeSat communications system.

This was the largest gathering of radio amateurs in India so far. Radio Amateurs and SWLs from all over the country and invited guests from other countries enjoyed the two-day event.

AMSAT-India gave several presentations at the event, among them was one by Ganesan Namachivayam KJ6LRR in which he described a satellite 435/145 MHz linear transponder with a bandwidth of 50 kHz and capable of 1-3 watts PEP output. AMSAT-India plan to develop a smaller linear transponder for CubeSats.

Ganesan also described a CubeSat communications system comprising a 435 MHz half-duplex narrow‐band FM transceiver supporting a data rate of 1200-9600 bps. The transmitter produces 1 watt output and can also operate as a Morse Code beacon.

Other presentations included:

  • Real Time Tracking by Mani VU2WMY
  • Working with LEO Sats by Dr. Raveendranath VU2RVJ
  • Telemetry Decoding by Nitin VU3TYG

Announcement of Opportunity: CubeSat Mission Concept Studies

The UK Space Agency is inviting proposals to develop CubeSat preparatory studies for future mission concepts e.g. UKube-2.

The core of the UK Space Agency strategy is to lead and sustain the growth of the UK Space Sector. In support of this the National Space Technology Programme (NSTP) promotes the development of new commercial and scientific applications by offering grant funding for truly novel concepts to be fully explored.

CubeSats offer huge potential to accelerate technology development of sensors and instruments in a package for deployment in space. New technology concepts for space missions can be demonstrated on CubeSat payloads, delivering a test bed at low cost and significantly reduced timescales. The CubeSat is a relatively new concept, which is maturing rapidly, in which the UK has existing leading capability.

This NSTP programme is to facilitate the acceleration of space technologies up the Technology Readiness Level (TRL) curve but can also attract new players into the space sector by offering a low cost route to getting flight heritage. To follow, the NSTP Pathfinder studies programme is to be released in early 2012 and will be specifically to develop technology concepts.

The UK Space Agency is currently funding a pilot programme, called Ukube1, to demonstrate the capabilities of a CubeSats with a launch towards the end of 2012. If successful, this pilot project could pave the way for a national programme starting in the third quarter of 2012, offering launch opportunities every 12-18 months. The aims of a national programme will also encompass the delivery of educational opportunities and science applications as well as testing new technologies.

Proposals are invited to develop CubeSat preparatory studies for future mission concepts e.g. UKube-2. The concept can address a scientific theme or be of an in-orbit technology demonstration nature (e.g. formation flying), providing a real impact to the UK. All UK based communities (academic, industrial and other) are invited to submit proposals. Applications can be made individually or in partnership with other organisations, however industry and academia will be funded under the rules stipulated in the scope of funding presented below.

Funding is available up to £35K per proposal; the size of award will depend on the requirements of the proposed project and the applicants’ case for support. Proposals should not exceed a grant value of £35K. Funding will be awarded in 2012 and the project cannot exceed 3 months duration. Due to the short nature of these studies and the amount of funding available, we intend funding successful applicants at the onset of the project. It is anticipated the scheme will fund a minimum of 7 proposals; the facility to fund more will depend on the size of awards and will be assessed on a competitive basis as detailed below.

The deadline for submission of proposals is 1st February 2012, 12pm.

Amateur Radio Satellites Approach Launch

Amateur radio CubeSats and ALMASat-1 being prepared for launch

The integration of Vega’s first, second and third stages is now complete at ESA’s Spaceport at Kourou in the Caribbean. ESA say the new rocket is moving full speed ahead towards its maiden flight at the end of January.

Vega will carry seven amateur radio satellites, ALMASat-1 and six Cubesats. The primary payload is LARES (Laser Relativity Satellite), a passive satellite with laser mirrors for the study of the Earth gravitational field and general relativity measurements (Lense-Thirring effect).

By the end of December, the six CubeSats, ALMASat-1 and LARES will be ready and enclosed in the fairing, well in time for the launch.

PW-Sat to launch in January

PW-Sat, a 1U CubeSat to be launched on the first VEGA flight in January, will carry a 435 to 145 MHz Amateur Radio transponder.

The single channel transponder will operate in a similar way to the amateur satellite AO-16. The uplink on 435.020 MHz will be FM and the downlink on 145.900 MHz will use the BPSK telemetry beacon transmitter to produce Double Sideband (DSB) that can be received on an SSB radio.

PW-Sat should be launched into a 1450 by 300 km 71 degree orbit and may be expected to have a lifetime of about 4 years before re-entry. It was built by students of Warsaw University of Technology in cooperation with the Space Research Centre and will be Poland’s first satellite.

PW-Sat has five modes of operation:
1. Receive only mode – no downlink
2. Beacon CW mode – Downlink On-Off Keying (OOK) CW (1kHz) 12 WPM on 145.900 MHz
3. Beacon BPSK mode – Downlink BPSK (3 kHz) 1200 bps AX25 (1 frame on 20 sec) on 145.900 MHz
4. Control communication mode. Downlink BPSK (3 kHz) 1200 bps AX25 on 145.900 MHz
5. Voice Repeater mode (aka “AO-16” mode) – Uplink 435.020 MHz FM (15 kHz) Downlink 145.900 DSB (3 kHz)
