Quectel Wireless Solutions is pleased to launch the LS550G, an ultra-compact multi-constellation GNSS module designed for fast and accurate positioning. With a 5mm x 5mm x 1.05mm form factor, the solution is well-suited for power- and space-sensitive applications, particularly those that need very thin modules, such as for portable and wearable devices.
The LS550G GNSS module supports concurrent reception of GPS, GLONASS, Galileo, BDS, QZSS and SBAS constellations, enhancing satellite visibility, reducing time to first fix, and improving positioning accuracy, particularly in dense urban environments. Equipped with dual integrated LNA, TCXO and RTC, the module offers high sensitivity, enabling accurate positioning, fast acquisition, and reliable performance even in challenging conditions.
The System-in-Package (SIP) technology helps to minimise the module’s size, delivering an ultra-compact form factor of just 5.0mm × 5.0mm × 1.05mm. This design not only saves space but also reduces signal attenuation, minimises interference, moisture ingress and corrosion and enhances shock resistance.
“The LS550G exemplifies our commitment to innovation in GNSS technology, offering exceptional performance in an ultra-compact form factor,” said Norbert Muhrer, President and CSO, Quectel Wireless Solutions. “With its multi-constellation support and advanced SIP design, the LS550G is the ideal solution for applications requiring high accuracy, low power and compact form factor even in the most challenging environments.
The module also features a -165dBm tracking and -147dBM acquisition sensitivity without an external LNA. It supports anti-jamming functionality with an embedded multi-tone active interference canceller, ensuring the module can mitigate or resist interference from unwanted signals that could disrupt its ability to accurately determine location.
The Enhanced Prediction Orbit on Chip (EPOC) technology allows the module to automatically calculate and predict satellite orbits using ephemeris data stored in internal RAM, valid for up to 3 days. This enables the LS550G to achieve fast position fixes, even under low signal conditions, while maintaining energy efficiency.
Its ultra-compact form factor and low power consumption features make it well-suited for applications such as wearable devices, sport and asset trackers, and elderly care products.
