Consumer electronics and automotive GPS receiver module-GPS, receiver module, Bluetooth – automotive electronics industry-hc360 HC Network
Consumer Electronic Equipment and automotive applications is GPS Receiver module's two largest fields of application. Consumer electronics equipment, power consumption, size and cost is a key demand for GPS receiver module. Especially when the number of portable devices require wireless capabilities, the use of integrated GPS, Bluetooth, FM and other wireless solutions can significantly reduce power consumption and reduced size.
For example, CSR launched the CSR9000 module has a very high level of integration, in less than 60 mm2 of the area to provide GPS, Bluetooth, low-power Bluetooth, Wi-Fi (IEEE802.11a/b/g/n ), FM transceiver functions. CSR9000 contains two chips (UF6000 + BC7820, or UF6000 + BC7830) and the external circuit design. CSR also Murata, Taiyo Yuden, Samsung Electro-Mechanics Co., Ltd. to jointly develop solutions based on CSR9000 ultra-compact integrated module.
U-blox's AMY module is the preferred space of compact equipment, which can be further integrated GPS functionality to more devices. AMY module based on u-blox5GPS engine, measuring only 6.5 × 8 × 1.2mm, the first positioning time is only 1s, sensitivity up to-160dBm. AMY module is a stand-alone receiver, in addition to the antenna and Power supply Outside does not need any external components, so the GPS receiver module based on the size of almost single-chip GPS receiver using existing chips and external circuits occupied half the space. In addition, the modules can greatly reduce the use of the products to add GPS functionality within the design work required, thereby reducing the overall cost.
Relative to the consumer GPS applications, GPS applications due to special circumstances, require not only locate and track high sensitivity and high accuracy position information, re-positioning time is short, also called the city, canyons and other harsh environments maintain a high Navigation Quality. In addition, GPS modules and components must be designed in a more wide temperature range.
U-blox u-blox5 provide chipset-based vehicle GPS receiver module. u-blox5 with 50-channel GPS architecture, more than 1 million correlators and separate acquisition and tracking engines, capable of a large number of parallel search, it has a high capture rate. u-blox5 chips and modules capture rate of less than a second satellite signal. In addition, because of its unique design and technology can inhibit human interference and reduce the multipath effect, u-blox5GPS receivers GPS device can make the most challenging environments (such as shopping malls, train stations and urban canyons) carried out operation. For example, based on u-blox5 the LEA-5 module is not only versatile, but also provides a flexible connection interface, its ease of integration features greatly shortened Car Applications to market.
Filter performance is critical to the performance of GPS products are the target, TriQuint Semiconductor, Inc. for the GPS global positioning satellite navigation system design of the new highly integrated RF modules TQM640002, in a small package will filter and low noise amplifier functions rolled into one . TQM640002 strong anti-interference ability, and size of only 3 × 3mm, very suitable for next generation mobile GPS portable devices as well as industrial and automotive and other applications.
