    India seeks global adoption of its NavIC system

    Logo: Indian Space Research OrganisationA new draft policy in India seeks to foster global use of its Indian NavIC satellite navigation system. The draft Indian Satellite Navigation Policy 2021 (SATNAV Policy 2021) is part of reforms of the Indian Space Research Organisation (ISRO)/Department of Space (DoS).

    “ISRO/DOS shall work towards expanding the coverage from regional to global to ensure availability of [the] NavIC standalone signal in any part of the world without relying on other GNSS and aid in wide utilization of [the] Indian navigation system across the globe,” states the policy document.

    DoS will push NavIC for global use to meet demand for positioning, navigation and timing in commercial, strategic and societal applications. It aims to ensure the continuous availability of free-to-air navigation signals for civilian uses, while providing secured navigation signals for strategic uses.

    The draft document plans for continuity of NavIC and GAGAN services, while also ensuring Indian satellite navigation and augmentation signals are compatible and interoperable with other GNSS/SBAS signals. The International Telecommunication Union (ITU) regulated frequency allocation to prevent interference among signals from different systems. This interoperability allows users to seamlessly switch from one constellation system to another and results in improved navigation signal, especially in a situation where an area is obscured from one satellite system.

    DoS will continue to work with ITU for frequency allocation. It will also take part in the United Nations Committee on Peaceful Uses of Outer Space (UNCOPUOS), International Civil Aviation Organisation (ICAO) and International Maritime Organisation (IMO).

    In addition, ISRO will provide technical support for academic institutions in GNSS research and applications.

    “Unacceptable! Never again!”: EC Deputy on Galileo outage

    Responding to a suggestion about the Galileo outage this past summer to the effect of “these things happen,” a senior European Commission (EC) official pushed back strongly, calling the event “Unacceptable!” and vowing “Never again!”

    The comments by Pierre Delsaux came during a question-and-answer session at breakfast hosted by the European Union on “EU Space Policy: Trends for the Future.” The breakfast was held as a parallel event to this year’s International Astronautics Conference in Washington, D.C.

    Delsaux is the European Commission Deputy Director General in charge of space and defense industries. In his presentation, Delsaux described the success of a number of European space initiatives, stressing civilian use and applications and how they have benefited the world.

    His comments highlighted a principle difference between Galileo and other GNSS systems including its being built and operated by an entirely civilian organization. With an accuracy of 20 centimeters, it exceeds other GNSS, he said. Also, that Galileo signals can be authenticated and trusted.

    Delsaux’s remarks were especially pertinent and timely being made this week in the United States. A strategy document recently made public by the U.S. Department of Defense states that civil dependence on GPS has limited its use as a military tool. Because of this, new military PNT technologies will be “increasingly classified,” which is understood to mean “not shared with civil users.”

    During the question-and-answer period, Delsaux was asked about criticism in the press this summer related to Galileo’s multi-day outage. European media outlets commented about poor communications and a lack of transparency during the outage, and the absence of a terrestrial backup system for when space is not available.

    Rejecting the idea that such outages might be expected in such a difficult undertaking, Delsaux said that the event was unacceptable and “never again!”

    While admitting things can always be done better, he thought that, given what was known with certainty at the time, a reasonable amount of information was made available.

    Subsequent investigation has shown that the primary cause was an initial human error compounded by that person not taking the right corrective action.

    Even with these compounded errors Galileo service would still not had been impacted, but for the mischance that this happened when a backup site was temporarily out of service.

    Going forward, the European Commission is committed to being as transparent as possible about the results of the investigation, given security constraints.

    Reinforcing the transparency message, other EC officials mentioned separately that Galileo personnel had given presentations about the outage at a recent Institute of Navigation Conference in Miami.

    Delsaux did not respond to press criticism over a lack of a backup system (the title of a Der Spiegel article about the Galileo failure translates as “Who relies on a single system is stupid!”).

    Later, other EC officials observed that that the European Radionavigation Plan recognizes that for critical applications, it is broadly accepted that GNSS, even multi-constellation and multifrequency, should not be the unique source of PNT information. For those applications, a complementary, alternative or backup solution should be maintained or developed.

    The EC is still developing its approach to this issue.
