On January 28, 2013, MediaTek, Inc., a global leader in wireless communication and digital multimedia IC design, today released the world's first SoC solution for the 5-in-1 global satellite navigation system receiver compatible with China's Beidou satellite Scheme MT3332 / MT3333. The Chinese Beidou satellite navigation system has been in operation since the end of 2012. Currently, 16 satellites provide positioning, navigation and timing services to the Asia-Pacific region. The positioning accuracy can reach 10 meters in plane and 10 meters in height; the accuracy of speed measurement is 0.2 meters per second. One-way timing accuracy is 10 nanoseconds. It is expected that its satellite signals will cover the whole world in 2020 and become one of the most important satellite navigation systems.
MediaTek's five-in-one global satellite navigation system receiver SoC MT3332 / MT3333 can support the signals of five global satellite navigation systems such as US GPS, Chinese Beidou, Russian GLONASS, EU Galileo, and Japanese QZSS. With the mutual assistance of multiple systems, it can Significantly improve the accuracy and reliability of navigation and positioning, and avoid the accumulation of errors with time and travel. MT3332 / MT3333 also has superior signal acquisition (AcquisiTIon) and tracking (Tracking) sensitivity, effectively improve the navigation system signal is blocked by the environment, whether in densely built cities, tunnels, or in multi-storey car parks , Can bring users more accurate and rapid navigation and positioning. MT3332 / MT3333's high system integration, low external component cost (BOM cost) and ultra-small layout (layout) area characteristics, allowing customers to complete the design of receivers of different systems on the same development board, suitable for each Mobile devices, industries and in-vehicle applications.
Cai Shouren, general manager of the Unicom Wireless Unicom Division, said: "With the use of wireless network and user location-based services (locaTIon-based services), such as social network check-in (check-in), find the nearest service point (nearby service recommending) and other popular applications, users have high standards for the accuracy and coverage of navigation system positioning. In the future, more smart phones and tablets with multiple global navigation satellite system (mulTI-GNSS) receivers will appear in the market Computers and in-vehicle electronic systems, because navigation and positioning applications have become an indispensable medium for people to interact and share each other ’s geographic information every day. MediaTek believes that the multiple global navigation satellite system receivers that support Beidou satellite system will be in the Chinese market in the next few years. Shipments will increase dramatically. MediaTek will also continue to improve positioning and navigation technology through product innovation, so that mobile users can transfer data more smoothly whenever and wherever, indoors or outdoors. "
MT3332 / MT3333 is equipped with MediaTek's unique "AlwaysLocate" software technology, which can determine the satellite signal receiving mode according to the user's state (such as when sleeping or driving), which makes navigation and positioning more accurate and reliable, and can effectively save navigation. The power of the system.
MediaTek MT3332 / MT3333 is now in mass production and is used in major satellite navigation system products and mobile communication platforms for global market sales.

A new rule from the Drug Enforcement Administration (DEA) threatens to upend the American hemp industry, and could even result in criminal prosecutions for manufacturers of CBD and delta-8 THC products.
The DEA says the [interim final rule," issued Aug. 20, is simply a matter of adjusting its own regulations to account for changes to the Controlled Substances Act that were mandated by the 2018 Farm Bill (or Agricultural Improvement Act) that legalized hemp and CBD production. The new rule [merely conforms DEA`s regulations to the statutory amendments to the CSA that have already taken effect," says the agency. The new rule doesn`t break any ground, according to the DEA.
But many experts on cannabis and hemp law say the DEA rule creates a potential pathway the law enforcement agency could use to prosecute hemp processors and producers of CBD (cannabidiol) and delta-8 THC (or Δ8THC) products. There are two issues: partially processed CBD, and [synthetically derived" delta-8 THC.
