Двухчастотный "сантиметровый" гнсс чип для мобильных устройств

Broadcom Limited (NASDAQ:AVGO), a leading designer, developer and global supplier of a broad range of digital and analog semiconductor connectivity solutions, today announced the world’s first mass-market, dual frequency GNSS receiver device, the BCM47755, designed to enhance location based services (LBS) applications for mobile phones, tablets and fitness wearables. Equipped with the latest GNSS innovations, the device is capable of centimeter accuracy with minimal power consumption and footprint, enabling an entirely new suite of high-precision LBS applications including lane-level vehicle navigation and mobile augmented reality (AR).

Until now, mobile location based applications have been powered by single frequency GNSS receivers operating under stringent battery power and footprint constraints. The expanded availability of L1/E1 and L5/E5 frequencies in satellite constellations enables the use of two frequencies to compute position much more accurately in both urban and open area environments. The BCM47755 delivers this higher level of location accuracy while meeting the rigorous battery power and footprint needs in mobile phones.
