Earth Scientists React to Possible Loss of Russian GPS Stations

first_imgA Russian government threat to disconnect 11 GPS receivers used for geophysical research and to fine-tune the satellite navigation system is drawing concern from scientists—and questions from the country’s minister for industry.The threat is just one element of the tit-for-tat diplomatic and rhetorical firefight that has broken out between Russia and the United States in the wake of Russia’s annexation of Crimea in Ukraine. Last week, senior Russian officials said they were considering an array of moves aimed at U.S. space programs, including pulling out of the International Space Station in 2020 and barring the use of Russian rocket motors by U.S. firms. Officials also threatened to turn off 11 land-based GPS receivers on Russian soil by 1 June unless the United States agreed to install similar units for Russia’s GLONASS satellite navigation system on U.S. territory.Experts say the shutdown—if carried out—would have little impact on GPS. The passive stations, which only receive GPS signals, are primarily used to ensure correct tracking of GPS satellites. “As these stations are very few, their impact on the accuracy of the positional measurements is insignificant,” says Konstantin Kuimov, head of the Moscow State University department of astrometry and time service. “The accuracy of the positioning at present is the question of decimeters. Now, it would worsen a little bit.” GPS users won’t notice any change, he says.Sign up for our daily newsletterGet more great content like this delivered right to you!Country *AfghanistanAland IslandsAlbaniaAlgeriaAndorraAngolaAnguillaAntarcticaAntigua and BarbudaArgentinaArmeniaArubaAustraliaAustriaAzerbaijanBahamasBahrainBangladeshBarbadosBelarusBelgiumBelizeBeninBermudaBhutanBolivia, Plurinational State ofBonaire, Sint Eustatius and SabaBosnia and HerzegovinaBotswanaBouvet IslandBrazilBritish Indian Ocean TerritoryBrunei DarussalamBulgariaBurkina FasoBurundiCambodiaCameroonCanadaCape VerdeCayman IslandsCentral African RepublicChadChileChinaChristmas IslandCocos (Keeling) IslandsColombiaComorosCongoCongo, The Democratic Republic of theCook IslandsCosta RicaCote D’IvoireCroatiaCubaCuraçaoCyprusCzech RepublicDenmarkDjiboutiDominicaDominican RepublicEcuadorEgyptEl SalvadorEquatorial GuineaEritreaEstoniaEthiopiaFalkland Islands (Malvinas)Faroe IslandsFijiFinlandFranceFrench GuianaFrench PolynesiaFrench Southern TerritoriesGabonGambiaGeorgiaGermanyGhanaGibraltarGreeceGreenlandGrenadaGuadeloupeGuatemalaGuernseyGuineaGuinea-BissauGuyanaHaitiHeard Island and Mcdonald IslandsHoly See (Vatican City State)HondurasHong KongHungaryIcelandIndiaIndonesiaIran, Islamic Republic ofIraqIrelandIsle of ManIsraelItalyJamaicaJapanJerseyJordanKazakhstanKenyaKiribatiKorea, Democratic People’s Republic ofKorea, Republic ofKuwaitKyrgyzstanLao People’s Democratic RepublicLatviaLebanonLesothoLiberiaLibyan Arab JamahiriyaLiechtensteinLithuaniaLuxembourgMacaoMacedonia, The Former Yugoslav Republic ofMadagascarMalawiMalaysiaMaldivesMaliMaltaMartiniqueMauritaniaMauritiusMayotteMexicoMoldova, Republic ofMonacoMongoliaMontenegroMontserratMoroccoMozambiqueMyanmarNamibiaNauruNepalNetherlandsNew CaledoniaNew ZealandNicaraguaNigerNigeriaNiueNorfolk IslandNorwayOmanPakistanPalestinianPanamaPapua New GuineaParaguayPeruPhilippinesPitcairnPolandPortugalQatarReunionRomaniaRussian FederationRWANDASaint Barthélemy Saint Helena, Ascension and Tristan da CunhaSaint Kitts and NevisSaint LuciaSaint Martin (French part)Saint Pierre and MiquelonSaint Vincent and the GrenadinesSamoaSan MarinoSao Tome and PrincipeSaudi ArabiaSenegalSerbiaSeychellesSierra LeoneSingaporeSint Maarten (Dutch part)SlovakiaSloveniaSolomon IslandsSomaliaSouth AfricaSouth Georgia and the South Sandwich IslandsSouth SudanSpainSri LankaSudanSurinameSvalbard and Jan MayenSwazilandSwedenSwitzerlandSyrian Arab RepublicTaiwanTajikistanTanzania, United Republic ofThailandTimor-LesteTogoTokelauTongaTrinidad and TobagoTunisiaTurkeyTurkmenistanTurks and Caicos IslandsTuvaluUgandaUkraineUnited Arab EmiratesUnited KingdomUnited StatesUruguayUzbekistanVanuatuVenezuela, Bolivarian Republic ofVietnamVirgin Islands, BritishWallis and FutunaWestern SaharaYemenZambiaZimbabweI also wish to receive emails from AAAS/Science and Science advertisers, including information on products, services and special offers which may include but are not limited to news, careers information & upcoming events.Required fields are included by an asterisk(*)The impact on science, however, could be a bit greater. That’s because earth scientists use data from the receivers to track the slow, subtle movements of continents and land surfaces. “The situation with geophysical measurement is much worse” because the receivers are vital to providing “a serious set of statistical data,” Kuimov says. “The statistical data makes it even possible to measure the variations in the rotation of the Earth and the seismic activity of the planet. It is only the positioning satellites that make it possible to measure the [movements] of the surface in millimeters.” Researchers use both navigation systems—GPS and GLONASS—to make such measurements, Kuimov notes. So he and other researchers would like to see GLONASS stations on U.S. territory (a move that has been under negotiation). Ideally, he says, such stations ultimately would be evenly spaced around the world.If Russia follows through with the threat, the impact will depend on how long the base stations remain inaccessible, says Jeffrey Freymueller, a geophysicist at the University of Alaska, Fairbanks. “If the Russians eventually share the data, we’ll be able to reprocess everything and eventually recover full precision results, but if they actually remove the equipment for the long term then over time it will become an increasing problem, as it will compromise the global coverage,” Freymueller says. “Before there were these stations in Russia, for example, it was difficult to do large-scale tectonic studies in China because we could not define what was the stable Eurasian plate well enough to express motions relative to stable Eurasia. Eventually, we will slip back toward that situation if there is no continuing data from Russia, although we still have the past data so it will never be as bad as it was.”The threat to turn off the receivers “is a purely political decision,” Kuimov says. “No one needs it except politicians. In fact, it just demonstrates Russia’s disloyal attitude [toward] the U.S., in response to the disloyal attitude of the U.S. [toward] Russia.”The threat also appears to have sown discord within the Russian government. On 13 May, the day after the threat surfaced, Denis Manturov, Russia’s minister of industry and trade, suggested that it didn’t make sense. “Technically, it can be done,” he said. “But what is the purpose of that?”With reporting by Vladimir Pokrovsky, Andrey Allakhverdov, and Yudhijit Bhattacharjee.last_img read more

FCPA Flash Podcast – A Conversation With James Noe Regarding FCPA Issues

first_imgThe FCPA Flash podcast provides in an audio format the same fresh, candid, and informed commentary about the Foreign Corrupt Practices Act and related topics as readers have come to expect from written posts on FCPA Professor.This FCPA Flash episode is a conversation with James Noe (special counsel with Jones Walker LLP who previously served in various in-house counsel and executive roles with several oil and gas companies). During the podcast, Noe discusses: the easiest and most difficult aspects of FCPA compliance in the oil and gas industry; the extent of facilitating payments in the industry; whether oil and gas companies are too risk averse when it comes to FCPA issues; and civil actions by industry participants when business is lost because of a refusal to make bribe payments.FCPA Flash is sponsored by Kreller Group.For the past 30 years, Kreller has distinguished itself as a best-in-class enhanced due diligence provider.
