50th Anniversary of the UK in Space

The United Kingdom sent up its first satellite 50 years ago when Ariel 1 launched on April 26, 1962. To celebrate the occassion BBC News interviewed radio amateur Sir Martin Sweeting G3YJO.

The launch of the joint UK/US satellite Ariel-1, also known as UK-1, made the United Kingdom the third country to operate a satellite, after the Soviet Union and the USA.

Deployed into a 1,202 by 397 km orbit Ariel-1 carried six experiments, five of these examined the relationship between two types of solar radiation and changes in the Earth’s ionosphere.

Ariel-1 marked the first time the UK sent something into orbit, and gave a lift-off for a part of the British economy that gets little attention but makes a lot of money.

In this BBC News report Adam Fleming speaks to Doug Millard at the Science Museum, Sir Martin Sweeting G3YJO from Surrey Satellite Technology and Space Minister David Willetts on the UK’s role in space today.

UK industry to build Solar Orbiter satellite

50 years of the UK in space

This is a year of momentous milestones in the life of Britain, ranging from Charles Dickens’ bicentenary to the Queen’s Diamond Jubilee. Adding further significance to 2012 is the UK space industry, which has a golden anniversary to mark: the launch of the nation’s first satellite, Ariel-1, on April 26th 1962.
In the news
Built by NASA in collaboration with a team of British academics, Ariel-1 was the world’s first international satellite, and constituted the foundation of the UK space sector – now annually worth £7.5 billion to the UK economy, and supportive of some 70,000 jobs across a variety of the nation’s industries.
To mark this special anniversary, the UK Space Agency is presenting a two-day space symposium on the 26th and 27th of April, at the home of their active co-hosts, the Science Museum. Now a year old, the UKSA has much to be enthusiastic about; and the symposium will commemorate past achievements, and explore the future direction of Britain’s thriving space industry – with contributions from some of the leading players in the sector today.

The UK Space Agency was founded to provide strategic support to the sector, while making significant investments through its 230m civil space budget. Almost 90 per cent of the agency’s budget currently goes to the European Space Agency, for collaborative pan-European space projects. This strategy is helping to secure Britain’s role as a key player in the development of Europe’s space going future.

SSTL is a case in point; with its current role in the European Commission’s European GNSS program. The company will assemble eight batches of satellite navigational payloads, on top of the 14 it is already building. In addition, the UK government recently announced that it would invest in the development of NovaSAR, SSTL’s small radar satellite. The space agency’s work signifies government recognition of the groundbreaking work in space technology by UK universities, research centres, and companies like SSTL.


SSTL is itself of historical significance, as the creator of the first ‘talking satellite’, UoSAT-1 in 1981. Their current work in nanosatellite and microsatellite technology, is a far cry from the ancestral Ariel-1, which had the aesthetics of a 1950’s ‘sci-fi’ fantasy space craft: multiple, sphere-like radio antennas protruding from a cylindrical body; multiple solar arrays; inertia booms to control the craft’s spin, and a 100-minute tape to store a single orbit’s worth of data.

Perhaps the most dramatic contrast in SSTL’s current work, to the ‘little-green-man’ craft that was Ariel-1, is its Smartphone satellite STRaND-1. This unique nanosatellite is designed around a Google Nexus One, Android Smartphone. In a playful nod to classic science-fictions’ dream of a space-going future, is the inclusion of an App on the phone that tests out the film Alien’s infamous slogan: ‘In space no-one can hear you scream’.

Providing SSTL’s contribution to the UK Space Agency’s symposium, will be Shaun Kenyon, lead System Engineer on the aforementioned, nanosatellite STRaND-1. On the 26th, 
he will discuss the importance of flagship projects and small satellites to UK space technology. Shaun’s insights will help to put in context the retrospective significance of Ariel-1, as he expounds his belief in the importance of satellite technology and low cost access to space for commercial endeavours.

FUNcube Dongle used in new Prospero X-3 Satellite Tests


Roger J A Duthie M0RJA and the team are carrying out further attempts to reactivate Prospero, the United Kingdom’s first satellite launched on a UK-built rocket, Black Arrow, on October 28, 1971.

The team now have an AMSAT-UK FUNcube Dongle (FCD) VHF/UHF Software Defined Radio to receive Prospero on 137.560 MHz and use an Icom IC-746 tranceiver on transmit commands to the satellite.

Because the frequency is now used by a number of Orbcomm satellites it can be difficult to identify the Prospero X-3 signal. The intention is to switch the satellite on and off by making commanding attempts and listening for a response in the RF carrier to indicate that Prospero is indeed still in some sort of working condition.

It is hoped Amateur Radio operators will be able to provide recordings of the signals on 137.560 MHz.

For further information check the Prospero X-3 blog and the AMSAT bulletin board.

Prospero X-3 Satellite Blog

An exciting spectrogram trace is revealed in the blog about the United Kingdom’s Prospero X-3 satellite that celebrated 40 years in orbit last month.

Prospero X-3 was the UK’s first satellite to be put into orbit by a UK-built rocket, Black Arrow. The launch took place from Launch Area 5B, Woomera on October 28, 1971 and the satellite operated successfully until 1973 after which it was contacted annually until being de-activated in 1996. In September 2011 a team from the  Mullard Space Science Laboratory announced their intention to try and re-activate the satellite.

In his blog Roger J A Duthie M0RJA notes the assistance the team has received from those in the Amateur Radio community including the AMSAT-BB mailing list, Roger reports that Tony Abbey G3OVH supplied a spectrogram, with a special Doppler shift correction added, of the radio transmission he received on 137.560 MHz . The team found that in this spectrogram, there was a signal from a source with a Doppler signature exactly matching the predicted signature of Prospero!

Prospero 40th Anniversary

Attempts are being made to reactivate Prospero, the United Kingdom’s first satellite launched on a UK-built rocket, Black Arrow, on October 28, 1971. It is hoped Amateur Radio operators will be able to provide recordings of the signals on 137.560 MHz.

On October 19, Roger M0RJA provided details of tests to be carried out over the following two weeks:

Some of you may have heard that a team in the UK are trying to re-contact an old British launched satellite for the anniversary of its launch (28th October 1971).

We’ve been given a licence to transmit [on the 148.25MHz command uplink] and will be testing our re-engineered ground-segment in the next fortnight.  The passes we are going to concentrate on will be as far out west as possible, as to minimise QRM from Europe.  Earth is a lot more EM noisy than it was in 1971.

If anyone wants to try and tune in to the downlink, you can help ID any response we get from the old bird. To avoid interference the downlink is only planned to be active when the satellite is in range of the United Kingdom. The passes [times UK local = GMT+1] are summarised here:

There are other passes, though these are the ones which are out west.  We’ll see how we do.

Update Oct 23:   A recording would be grand.  We may have heard something on Friday [Oct 21], though we’re still piecing together what we can expect.  If recordings are made of the times when Prospero is to pass then we can get an idea of what everyone is hearing now.

On Friday we listened to a complete pass and definitely heard something different when Prospero was in our vicinity.  Whether this was coincidence with some QRM we don’t know.  As long as others aren’t transmitting at the same time as us on the Prospero frequencies, we have a reasonable chance to apply the scientific method to be certain of what we’re listening to.

We probably won’t make another attempt till Monday [Oct 24] – and we will probably try the passes at around 1800. [UK Local (GMT+1)]

There is information on this on the AMSAT-UK site front page:  this includes the passes we’ve marked out for definite attempts (we may try others) and there are some archived recordings of Prospero to compare to.

Wiki – Prospero

John Wright G4DMF says the Prospero satellite was featured in a BBC show called “Coast” Series 2 Episode 1 Dover to Isle of White. The item titled ‘Isle of Wight – UK’s Space Race of the 60’s’ showed an attempt to receive the signals using what appeared to be an AR2000. The show also dealt with the research into the propellants, and the launch from Australia.
Roger M0RJA says he thinks that what was received on Coast was almost certainly an Orbcomm transmission. Orbcomm was assigned the Prospero frequency.
