The planned UK spaceport is sited to launch cubesats into polar orbit. There are an increasing number of commercial options for launching any GPS system such Falcon/Falcon Heavy at reasonable cost.

Shame spectrum management means we wont have any usable frequencies. and im still bermused to see how microsat will have an accurate enough and strong enough signal to provide jam resistance, whilst hosted on a transmission platform whose orbit is changing by metres per day.

I call b*llsh*t. If the Europeans could have developed a system that is as equally capable for a fraction of the price, why didnt they do that? or is this just a case of us wanting our cake and eating it and are too embarrassed to point out to brexiteers there are very real consequenses of leaving the EU that brexit voters didnt have the intellect to figure out?

I was making the point the UK spaceport would be used to launch any such system and is a red herring.

I recall that the quantum compass/INAS, funded by the MOD and demonstrated last month was described as “commercially ready” and, perhaps, may indicate why the government felt confident enough to withdraw from Galileo.

Always good to be optimistic , but not holding my breath here ; Still ongoing arguments in the MOD about which variant of the F 35 to fund. Meanwhile , at a more mundane level , news reports of married quarters being left empty / vandalised / burnt down ( RAFManby Officers Mess) at a cost of quite a few millions to the taxpayer doesn't exactly inspire confidence . As I said , could be a while before any decisions are made regarding any UK funded satellite constellations .. Our grand kids may see it .

I guess the writing was on the wall when we gave up launching stuff from Woomera .. Meanwhile , it's full steam ahead for ESA at Kourou.

Phantom Driver,

"RAF" Manby has not been an MoD asset for over 44 years, what on earth does it's burning down have to do with the taxpayer?

pr00ne,

You are certainly right about Manby ( incidentally will always be fondly remembered as "RAF Manby" by those who had the pleasure of attending courses there ) . Sadly , the Officers Mess remained derelict for most of those 44 years till it's fiery demise ( discussed on an earlier thread ) . It came to mind after a report aired last week on army married quarters left empty and in states of disrepair/vandalism . The (apparent) explanation from MoD was---they were on standby for possible reoccupation by service personnel in the future . The hope is they don't end up like O/M Manby . (Meanwhile , there is the ongoing debate about housing shortage ) .

Back to topic ; my main point is--I don't envy the decision makers at the moment , but those who believe a UK funded version of Galileo will be in orbit any time soon could be in for a long wait . Hopefully , MoD have a Plan B......

What does Britain have in the works for its upcoming space strategy?

WASHINGTON — For months, analysts and industry have been waiting on the release of a new space strategy for the United Kingdom, one that would lay out steps forward for the U.K.’s future in the increasingly important war-fighting domain. But the report has yet to materialize, even after Defence Secretary Gavin Williamson pledged it would be out before the end of 2018. So when might the document roll out?

According to Gen. Gordon Messenger, the U.K.’s vice chief of the Defence Staff, the government expects to release an interim report in the spring/summer time frame, with the final report coming later in the year, following the government’s conclusion of the comprehensive spending review, which will set London’s budget for several years. As to why the document was delayed: “The reason is because we want it to have some substance,” Messenger told Defense News during a recent visit to Washington.

“We just wanted to signpost a little bit more substance to industry and to our partners on where we sit in terms of space capability. And [so we paused] just to reflect a little when we were at risk of producing a very broad policy statement rather than something that might have a little bit more substance to it. I’m guilty of delaying it, and I think it would be difficult for us to push out anything of substance before the spending review now, to be honest,” he added, opining that industry should feel more confident the document will have money attached, as it will be released after the spending review.

During the interview, Messenger outlined a few priorities for that document: first, the development of a geostationary orbit for communications to bolster the U.K.’s Skynet constellation; and second, a replacement for the capability gap that now exists after the European Union pushed Britain out of the Galileo program. “We are examining a number of options, not all of them space-based, to look at the gap that Galileo was designed to deliver, now that we are almost certainly no longer in the Galileo program,” he said. “That’s quite a complex debate, but certainly has a space dimension to it.”

Finally, he noted that the U.K. is looking at the “merits” of a low-Earth orbit constellation for a “variety of potential uses.” That is notable, as the U.S. Defense Department is prioritizing the creation and launch of a low-Earth orbit constellation. Given close ties between the U.S. and the U.K. on defense matters, including intelligence sharing and strategic weapons, it is possible the two could find common ground on such a system.

Messenger confirmed he talked about that program while meeting with Pentagon research head Mike Griffin, the driving force behind that constellation.

Could this maybe mean the possibility of a further extension for Sentinel?

EU’s satellite navigation system fully offline


The EU's satellite navigation system, developed as an alternative to the United States' GPS, is fully offline due to "a technical incident related to its ground infrastructure," the bloc's space agency said Sunday.

"The incident has led to a temporary interruption of the Galileo initial navigation and timing services," the Prague-based European Global Navigation Satellite Systems Agency said, adding that Galileo's search and rescue system used to locate distress signals at sea or in mountainous regions was still operational.

Galileo is the world's fourth geo-location satellite system, after ones created by the U.S, Russia and China, and has been pitched by the EU as a more accurate alternative to GPS. The EU has poured some €10 billion into the system, which has operated on a trial basis since late 2016 and is set to be fully operational by the mid-2020s with 30 satellites in orbit.

The current problems with the nascent system were first reported on Thursday, but by Saturday evening, all 22 satellites in orbit were listed as offline. On Sunday, a public notice was posted and GNSS has so far given no timeline for fixing the issue.

Currently, only a limited number of consumer mobile phones are equipped to pick up Galileo's signal. In the meantime, GPS is used to augment Galileo and spot problems with the new system, GNSS said.

Another massive EU debacle "in the making" ?

TBH one isn't surprised;.. perhaps the growing economic uncertainty within the "Union" has led to a reduction in funding....


..or perhaps the migrant bill has spiralled somewhat upwards..







Muhahahahahahaha.....

“ (A) source told InsideGNSS.com that the problem may be related to faults with the Italy-based Precise Timing Facility ground station. The facility is equipped with Cesium clocks and a Hydrogen Maser clock, and uploads its data to the orbiting satellites to provide accurate time reference and make user localization possible.”......

Steamy, your link just points at individual PRNs going out, measured in hours. Do you have one for the entire constellation, preferably measured in days?

New UK space strategy sets the stage for defense investments

LONDON – Britain gave a broad view of where the country is heading in the defense space sector as it launched a national space strategy Sept. 27, but details about London’s military ambitions were largely absent from the document.

For a while, the government’s plan had been to release the national space strategy and an associated defense space strategy in tandem, but publication of the two documents has now drifted apart.

One space industry executive, who asked not to be named while discussing internal deliberations, said industry had been told a more defense-specific strategy was still incomplete and would have to wait until sometime next month for publication.….

Among the key developments include the first space launch from a UK spaceport, planned for next year, building a military-civil National Space Operations Centre, and creating the ministry’s new Space Command, which went operational earlier this year.….

Developing independent space domain awareness capabilities to protect UK satellites, advancing the
Skynet 6 communications satellite program and building a small constellation of intelligence, surveillance and reconnaissance satellites with supporting architectures are part of the investment ambitions outlined by the strategy.….

Among the capabilities name-checked by the strategy document as being of interest were the dual-use applications of free-space optical communications systems…..

The government is also continuing to evaluate the case for investing in resilient Position, Navigation and Timing (PNT) capabilities through a mix of innovative new terrestrial and space-based technologies……

New UK Defense Satellite To Pave Way Toward ISR Constellation

LONDON—The UK Ministry of Defense has ordered the first satellite to support the development of its Minerva constellation, the communications backbone for a family of synthetic aperture radar (SAR) satellites.

The UK will spend £22 million ($29 million) on the 150-kg (330-lb.) Carbonite+ to be developed by Surrey Satellite Technology Ltd (SSTL), the manufacturer and defense ministry announced April 4.

Carbonite+ will support Project Tyche, which is described by SSTL as a “key enabler” for the development of Minerva, which will provide a broadband link from the planned £970 million ISTARI SAR constellation back to commanders on the ground.

Developing the ISTARI constellation is one of the main ambitions of the UK’s Defense Space Strategy published in February.

“The Minerva program provides the route to use space to be fully interoperable and able to share data with our close allies,” UK Defense Procurement minister Jeremy Quin said. “This is the crucial first step in delivering this capability and I’m delighted that we’re working together with UK companies to remain at the forefront of innovation in space.”

The Tyche project aims to provide the UK’s Space Command with an “understanding and analysis of the integration activities, test environments and interfaces required to establish and maintain UK MOD rights to freely operate a space-based Intelligence Surveillance and Reconnaissance (ISR) capability,” SSTL states.

The project also will help the UK defense ministry better understand security requirements and risks, and to identify further activities that may be required to mature the planned ISTARI ISR capability.

According to SSTL, the Carbonite+ satellite will be delivered through a three-year build program and will be suitable for either horizontal or vertical launch.

The satellite will be operated from SSTL’s facilities in Guildford, England.
