Sony GNSS receivers. (left) CXD5610GF, (right) CXD5610GG. (Image: Sony) Sony Corporation plans to release a high-precision GNSS receiver for use in internet of things (IoT) and wearable devices. The new receivers have low power consumption for dual-band positioning operation — as little as 9 mW. Increasing use of IoT and wearable devices that utilize location information has resulted in growing demand for GNSS receiver LSIs. Precise positioning and reliable communications must be ensured to maintain proper operation of IoT and wearable devices, which are being used even in difficult communication environments and unstable conditions, such as multipath propagation situations caused by reflection off the ground or nearby buildings or the effects of the swinging of the arms when attached to a person’s wrist. Additionally, device size constraints necessitate a compact battery, whereas satellite signal reception and positioning when using GNSS functionality typically consumes a lot of power, resulting in poor battery life. The new LSIs support not only the conventional L1 band reception, but also L5 band reception, which is currently being expanded across GNSS constellations, thereby making them capable of dual-band positioning. Sony’s original algorithms enable stable, high-precision positioning even under the difficult conditions unique to wearable devices. Also, the use of Sony’s original high-frequency analog circuit technology and digital processing technology delivers low power consumption during continuous positioning for dual-band reception operation. The new LSIs will drive greater opportunities to develop new products and services such as smartwatches and other wearable devices that cannot use external power supplies, as well as IoT devices used for applications such as trackers. They also show promise in a wide variety of applications which require precise positioning and stable communications, such as automotive services. High-precision, stable positioning via dual-band operation Compared with the L1 band, the new signal method used in the L5 band employs signal units that are 10 times narrower to measure the range between the GNSS satellite and receiver, improving positioning precision and amplifying the transmission power from the satellite, resulting in high-precision, high-sensitivity positioning. Quick, accurate GNSS signal reception via Sony’s original algorithms enables positioning that is more stable than conventional products even in changing reception environments, such as obstructing from buildings when on the move and acceleration of wearables due to swinging of the arms. This also leads to quick positioning time even from cold starts, which require more time. Additionally, Sony’s original digital signal processing technology enables countermeasures against the performance degradation caused by radio interference from aircraft communications as well as spoofing attacks and other issues, thereby improving resistance to interference. Low power consumption and high sensitivity are delivered by Sony’s original analog circuit technology, which enables low-voltage operation, as well as digital circuits and software algorithms that enable software processing via low clock frequencies. This innovative design keeps power consumption to only 9 mW, the lowest in the industry, when simultaneously receiving signals in both the L1 and L5 bands. Built-in memory The new LSI’s feature built-in non-volatile memory for storing firmware, etc. This design makes it possible to update the firmware without adding externally mounted memory and contributes to a more compact design for IoT and wearable devices by saving space. It also makes it possible to complete data-processing in the products, resulting in low power consumption and improved access speed. Key specifications Power Consumption 1.5 GHz/1.2 GHz simultaneous reception 9 mW 11 mW 1.5 GHz reception 6 mW 7 mW 1.2 GHz reception 7 mW 8 mW Hot Start Sensitivity: –163dBm Tracking Sensitivity: –167dBm Hot Start Initial Positioning Calculation Time: Less than 1 second (at -130dBm) User Interface: UART, I2C, SPI Package: XFBGA 54 pin, LFBGA 72 pin External Dimensions (LWH): 3.2×3.7×0.5 mm; 7.0×8.0×1.4 mm
