resetting the time reference in the American GPS system, which will occur on the night of April 7, will not affect the vital consumers and owners of new navigation equipment, told RIA Novosti in the All-Russian Research Institute of Physical-Technical Measurements, which stores the Russian time standard. On the night of April 6-7, 2019, the American GPS system will "reset" its watch. The system uses a counter that is able to track a maximum of 1024 weeks, that is, it works for about 19 and a half years. The previous countdown began in August 1999. In connection with the reset of the countdown on the old navigation devices, the wrong date will start to be displayed, since the week number is received by the navigation equipment as part of the message from the satellite. The next such time reset will happen on November 20, 2038. "Modern receivers of all global navigation satellite systems, as a rule, are initially equipped with software with an automatic system for updating data upon reception of a signal. Consumers, in whose work it is vital to track accurate data of signals from global navigation satellite systems and synchronize over time, update their technical equipment and They know in advance about the capabilities of their devices, "the institute said. They clarified that problems with obtaining incorrect time may arise for the equipment of a very old generation, which is already practically in few places used and applied. Alexey Smyatskikh, Director General of the Russian navigation holding SpaceTim, adheres to a similar position. “We don’t think that the“ failures ”in the work of GPS will somehow affect the work of modern navigation equipment made in Russia,” he said. According to him, the owners of GLONASS / GPS navigation receivers or more modern multi-system receivers receiving data from GPS, GLONASS, European Galileo and Chinese BeiDou will not notice the problem, they will continue to receive stable navigation data and an accurate time signal. The other day, the Public Relations Directorate of the 50th Wing of the US Air Force Base, Shriver, issued an appeal to GPS users. In connection with the upcoming “zeroing” of the date, civilian consumers were advised to report possible problems with the system to the Coast Guard Navigation Center, civil aviation pilots to report GPS abnormalities to the Federal Aviation Administration, and military users to contact the GPS Operations Center. In turn, the Department of Homeland Security published a memorandum in which it warned GPS users about possible malfunctions in the work of even that user equipment that is manufactured according to modern standards.
