12017-06-22. Компания Spirent обнародовала свои планы.
Разработчик приемников и имитаторов сигналов глобальных навигационных систем обнародовала данные, согласно которым к 2020 году точность определения координат при помощи его устройств составит несколько сантиметров. Технической основой для подобного прогноза было заявлено окончание этапа развертывания основных навигационных группировок КА, что должно будет позволить использовать их возможности в рамках одного изделия. В Spirent также связали дальнейший рост продаж с темпами роста сектора Интернета для Вещей. Тэги: SpirentНавигационные

SPIRENT GSS6300 GNSS SIGNAL GENERATOR The GSS6300 GNSS Signal Generator from Spirent has been designed specifically for high volume production test applications for devices that use commercial GPS/SBAS/QZSS, GLONASS, BeiDou and Galileo receivers. Key Features n n Single channel GPS/SBAS/QZSS L1 C/A and/or GLONASS L1 C/A and/or BeiDou-2 B1 and/or Galileo E1 signals in one chassis Easily field upgradable to add GLONASS and/or BeiDou and/or Galileo and/or QZSS to existing GSS6300 chassis n IEEE-488, USB or RS-232 control interfaces The GSS6300 GNSS Signal Generator can be configured with one channel of GPS only, or with multiple constellations. It is easily upgradable in the field to add QZSS and/or GLONASS and/or BeiDou and/or Galileo test capabilities to an existing GSS6300 unit. Typical configurations include: n GPS only, GLONASS only, BeiDou only, Galileo only n GPS and GLONASS n GPS and BeiDou n GPS and Galileo n GPS and QZSS n GPS, GLONASS and BeiDou Equivalent GPS performance to Spirent’s proven GSS6100 n GPS, GLONASS and Galileo n Alternative “instant start” continuous run mode n GPS, QZSS, GLONASS, BeiDou and Galileo n Supplied with Spirent SimCHANTM software n Industry leading accuracy, fidelity and reliability To support varying test requirements, the GSS6300 can be controlled remotely via standard interfaces including IEEE-488, USB or RS-232. Alternatively, Spirent SimCHANTM software is provided to enable real-time user control of the GSS6300 as precision laboratory GPS/SBAS/QZSS, GLONASS, BeiDou and/or Galileo test equipment. n n A GSS6300 configured with GPS supports L1 SBAS messages n Comprehensive remote command set for easy ATE integration n Rack mount 2U chassis n In-rack annual calibration n Interactive run time control over power level, Doppler, PRN, GPS time and data message for each GNSS signal n The GSS6300 GPS/SBAS performance is equivalent to Spirent’s proven GSS6100 Single Channel Production Test System. In addition, the GSS6300 offers QZSS, GLONASS, BeiDou and Galileo test capabilities to support your evolving GNSS testing needs May be synchronized to external systems via 1PPS/Trigger, reference frequency input/output and 1PPS output Please contact us for further information. We will be pleased to discuss your specific requirements.
