    Lockheed Martin invests in Xona’s commercial navigation constellation

    Xona Space Systems, a company developing navigation technologies from low-Earth orbit (LEO), has received investment backing from numerous companies, including Lockheed Martin. Its latest financing round was oversubscribed, bringing the start-up’s total funding to more than $25 million.

    Xona is developing a high-performance commercial satellite navigation network, named Pulsar. Pulsar is a LEO system designed to provide resilient and trusted centimeter-level position anywhere on the globe.

    Within the past year, Xona more than doubled its number of full-time employees, launched its first orbital mission, and signed agreements with major players across the GPS/GNSS ecosystem such as Hexagon | NovAtel and Spirent Federal.

    The funding round was led by First Spark Ventures, who is joined by numerous new investors including Lockheed Martin Ventures, SRI Ventures (of SRI International), Velvet Sea Ventures, Gaingels, Airstream Venture Partners and Space VC. Existing investors also continue to show firm conviction in Xona’s accomplishments and market opportunity with participation from Seraphim Space, Toyota Ventures, 1517 Fund, MaC Venture Capital and Stellar Ventures.

    The new capital will accelerate development of Pulsar through several critical design milestones by expanding the team and building out Xona’s new R&D and manufacturing facility in Burlingame, California. This will enable more rapid design cycles and prepare for production.

    Xona’s first demonstration mission, Huginn, was successfully launched in May, and its second mission, Muninn, is planned to launch in 2023.

    “Xona’s approach to GNSS is poised to enable a whole new class of robust and reliable solutions in everything from automotive to drones,” said Manish Kothari, managing director of First Spark. “This is a technically challenging problem — a problem the Xona team is uniquely qualified and experienced to address. We are very excited to be part of this journey with them.”

    Xona’s core mission is to enable modern technology to operate safely in any environment, anywhere on Earth. To achieve this in industries such as automotive autonomy, drones and aerial mobility, precise knowledge of location and time is critical, and it must be robust against sources of potential interference or degradation. This is driving a need for global infrastructure that can support the demands of these applications as they continue to expand in both capability and geography.

    “The massive domain expertise of our supporters in everything from scaling global companies to deep technical knowledge of GNSS is both a validation of our team’s capabilities and a catalyst that has been instrumental in our growth and speed,” said Xona CEO Brian Manning.

    “As customer needs evolve, Lockheed Martin Ventures continues to work with companies we believe are on the forefront of emerging technology and that support increasingly resilient, hybrid systems,” said Chris Moran, vice president and general manager of Lockheed Martin Ventures. “We invested in Xona so they can continue to develop and build their commercial system to complement the greater GNSS architecture.”

    “The world would look very different today without GPS,” said Xona CTO Tyler Reid. “The ubiquitous robust precision that Pulsar can provide has potential to make the same level of global impact, not only in present and emerging markets, but we believe this global high precision can also enable entirely new devices and apps that we haven’t even thought of yet.”

    China is planning to complete its updated navigation constellation by 2020, according to China’s news service Xinhuanet.

    With 35 satellites, the completed BeiDou-3 will provide better coverage inside buildings and in urban canyons, according to researcher Jin Shuanggen, Shanghai Astronomical Observatory. Shuanggen was addressing the second Beidou Summit Forum.

    China has deployed three systems, BDS-1, BDS-2 and BDS-3, to provide accurate positioning and navigation services to the world, said Jin Shuanggen, a researcher at the Chinese Academy of Sciences, at the second China (Nanjing) BeiDou Satellite Navigation Application Expo and Beidou Summit Forum.

    The BDS system currently has 38 in-orbit satellites including 18 BDS-2 and 20 BDS-3.

    “Traditional satellites navigation service is hardly available in the interior of buildings, underground, underwater and other locations. The BDS system provides better accuracy in these locations,” he said.

    “BDS will play a large role as it is used in different scenarios including smart city, agriculture and meteorology, autopilot, and intelligent transportation,” said Jing Guifei, dean of BeiDou Belt and Road School of Beihang University.

    Along with the summit, a three-day exposition displayed BeiDou applications with more than 400 exhibitors. Fields covered included drones, autonomous ships, surveying and mapping, and intelligent robots and vehicles.

  • Another BeiDou launch adds to China’s constellation

    China successfully sent twin BeiDou navigation satellites into space on Aug. 25, aboard a single carrier rocket, according to news reports. The satellites are numbers 35 and 36 in the BeiDou navigation constellation.

    Only a few weeks ago, China launched another pair of BeiDou-3 navigation satellites.

    The Long March-3B carrier rocket lifted off from Xichang Satellite Launch Center in Southwest China’s Sichuan Province at 7:52 a.m. local time.

    This was China’s 23rd orbital launch this year, surpassing the national record of 22 launches set in 2016. China Aerospace Science and Technology Corporation (CASC), the main contractor for the space program, is planning on 35 launches this year.

  • Four more Galileo satellites launched into orbit

    Four more Galileo satellites launched into orbit

    Updated with additional details and reaction.

    On Dec. 12, four more Galileo satellites headed into space to join the navigation constellation. Galileos 19–22 lifted off aboard an Ariane 5 rocket from Europe’s Spaceport in Kourou, French Guiana, at 18:36 UTC (19:36 CET, 15:36 local time).

    After today’s successful launch, only one more launch remains before the Galileo constellation is complete and delivering global coverage.

    Separation of the upper stage occurred about nine minutes after liftoff, followed by the first firing of the upper stage.

    The first pair of 715-kg satellites was released almost 3 hours 36 minutes after liftoff, while the second pair separated 20 minutes later.

    They were released into their target 22,922 km-altitude orbit by the dispenser atop the Ariane 5 upper stage. In the coming days, this quartet will be steered into their final working orbits. There, they will begin around six months of tests — performed by the European Global Navigation Satellite System Agency (GSA) — to check they are ready to join the working Galileo constellation.

    This mission brings the Galileo system to 22 satellites. Initial Services began almost a year ago, on Dec. 15, 2016.

    “Today’s launch is another great achievement, taking us within one step of completing the constellation,” remarked Jan Wörner, ESA’s director general.

    “It is a great achievement of our industrial partners OHB (DE) and SSTL (GB) for the satellites, as well as Thales-Alenia-Space (FR, IT) and Airbus Defense and Space (GB, FR) for the ground segment and all their subcontractors throughout Europe, that Europe now has a formidable global satellite navigation system with remarkable performance.”

    Paul Verhoef, ESA’s director of navigation, added, “ESA is the design agent, system engineer and procurement agent of Galileo on behalf of the European Commission. Galileo is now an operating reality, so, in July, operational oversight of the system was passed to the GSA.

    “Accordingly, GSA took control of these satellites as soon as they separated from their launcher, with ESA maintaining an advisory role. This productive partnership will continue with the next Galileo launch, by Ariane 5 in mid-2018.

    “Meanwhile, ESA is also working with the European Commission and GSA on dedicated research and development efforts and system design to begin the procurement of the Galileo Second Generation, along with other future navigation technologies.”

    Next year’s launch of another quartet will bring the 24‑satellite Galileo constellation to the point of completion, plus two orbital spares.
