GPS & GLONASS

Digi XBee GPS Daughter Board for use with XBIB-C Development Boards (XBee module and XBIB-C Development Boards not included) This tool is an expansion module for the Digi XBIB-C board. Based on the leading U-blox CAM-M8 GPS receiver, the Digi XBee GPS Daughter Board allows developers to quickly and easily add GPS location tracking to applications incorporating Digi XBee modules. Digi provides developers with complete reference design resources, including schematics, gerber files and code, as well as a MicroPython library with code examples for incorporating GPS.

L76, the extremely compact GNSS module, is a concurrent GNSS receiver with multiple GNSS systems. It provides simultaneous GPS, GLONASS, Galileo, BDS and QZSS open service L1 reception capability. With 33 tracking channels, 99 acquisition channels, and 210 PRN channels, L76 can acquire and track any mix of multiple satellite signals. Compared with using GPS only, enabling multiple GNSS systems generally increases the number of visible satellites, reduces the time to first fix and increases positioning accuracy, especially when driving in rough urban environments. Combining advanced AGNSS called EASY™ (Embedded Assist System) and proven AlwaysLocate™ technology, L76 achieves the highest performance and fully meets the industrial standard. Additional feature of embedded logger function called LOCUS allows L76 to log position information to internal flash memory at default intervals of 15 seconds and provide typically more than 16 hours log capacity without adding cost. Its super performance makes L76 ideal for automotive, industrial PDA, consumer and industry applications. Extremely low power consumption makes it easier to be applied to power sensitive devices, especially portable applications.

Features

The L86 is a POT (patch antenna on top) GNSS module with 99 acquisition channels and 33 tracking channels. It is designed to be compatible with Quectel’s GPS L80 module to provide a flexible and scalable platform for migrating from GPS to GNSS. With an LCC package, integrated patch antenna and new generation MediaTek MT3333 GNSS chipset, the L86 has exceptional performance both in acquisition and tracking, and its space-saving design makes the module ideal for miniature devices. The L86 combines EASY (Embedded Assist System for self-generated orbit prediction) with LOCUS (internal logger) and AlwaysLocate to achieve excellent accuracy with low power consumption. The EASY allows the module to calculate and predict orbits automatically using up to 3 days of ephemeris data stored in the RAM, so it can fix position quickly and with low power consumption, even when signal levels are lower. The LOCUS allows the module to log position information to the internal flash memory at default intervals of 15 seconds, typically providing more than 16 hours log capacity without extra cost. AlwaysLocate allows the L86 to adjust the on/off time adaptively to achieve balance between positioning accuracy and power consumption, according to environmental and motion conditions. The L86 also supports automatic antenna switching, switching between internal patch antenna and external active antenna while maintaining positioning. The L86’s ultra-compact design, low cost and low power demands, combined with its excellent precision and high sensitivity, make the L86 suitable for a broad range of IoT applications such as portable devices, automotive, personal tracking, security and industrial PDAs. The module is especially suitable for special applications like GPS mouse receivers and on-board diagnostics.

Features

Based on the latest enhanced chipset, Quectel’s new LC76G GNSS module supports concurrent reception of GPS, GLONASS, BDS, Galileo and QZSS. The LC76G is designed to be compatible with Quectel L76 and L76-LB modules, allowing for smooth migration between them. Compared with single constellation receivers, by enabling multiple GNSS constellations, the LC76G module increases the number of visible satellites, reduces the time to first fix and improves positioning accuracy, especially when driving through dense urban canyons. The integrated LNA that delivers high sensitivity effectuates high accuracy positioning, fast signal tracking and acquisition and better performance even in challenging environments. By combining EASY™ (Embedded Assist System), an advanced AGNSS feature, with GLP* (GNSS Low Power), a low-power mode, the LC76G achieves high performance with low power consumption and fully meets the industrial standards. EASY™ technology allows the module to calculate and predict orbits automatically by using the ephemeris data (duration of up to 3 days) stored in the internal RAM. As a result, the LC76G acquires a position fix quickly, even at lower signal levels with low power consumption. Moreover, with the GLP* technology, the LC76G can adaptively adjust the on/off time based on the environmental and motion conditions to achieve a balance between the positioning accuracy and power consumption. Due to its enhanced performance the LC76G is ideal for consumer and industrial applications, and extremely low power consumption makes it a preferred solution for power-sensitive applications such as portable devices.
