Quectel - LS550G (00)
Ultra-compact GNSS module
Based on the latest enhanced chipset, the Quectel LS550G (00) GNSS module supports concurrent reception of GPS, GLONASS, Galileo, BDS and QZSS constellations. The SIP (System in Package) technology significantly reduces the module package size, achieving an ultracompact form factor of 5.0 mm × 5.0 mm × 1.05 mm. Additionally, the ultracompact SIP design contributes to lower signal attenuation, reduced interference, and improved resistance to shock, moisture, and corrosion.
Compared with single constellation receivers, the multi-constellation system on the LS550G (00) increases the number of visible satellites, reduces the time to first fix and improves positioning accuracy, especially in dense urban canyons. The integrated LNA delivers high sensitivity, facilitates high accuracy positioning, enables fast signal tracking and acquisition, and enhances module performance even in challenging environments.
By combining enhanced prediction orbit on chip (EPOC) technology—an advanced AGNSS feature — with adaptive low power (ALP) mode, the LS550G (00) module achieves high performance, low power consumption, and compliance with industrial standards. EPOC technology enables the module to calculate and predict satellite orbits automatically by using the ephemeris data (valid up to 3 days) stored in the internal RAM. As a result, the LS550G (00) obtains a position fix quickly, even at lower signal levels, while maintaining low power consumption. With the ALP technology, the LS550G (00) adaptively adjusts its on/off time based on environmental and motion conditions to achieve a balance between positioning accuracy and power consumption.
Enhanced performance makes LS550G (00) well-suited for a variety of consumer and industrial applications, including industrial PDAs. Its ultracompact form factor and low power consumption make it a preferred solution for power sensitive and space-sensitive applications, such as portable and wearable devices.
