With 33 tracking channels, 99 acquisition channels, and 210 PRN channels, the module provides fast time-to-first-fix and high positioning accuracy even in challenging urban canyon environments. The integrated LNA (Low Noise Amplifier) achieves industry-leading -166dBm tracking sensitivity and -147dBm acquisition sensitivity. EASY (Embedded Assist System) technology automatically calculates and predicts orbits using up to 3 days of stored ephemeris data for quick fixes at lower power. ALP (Adaptive Low Power) technology dynamically adjusts on\/off time based on environmental conditions. The module is footprint-compatible with Quectel L26 and L26-LB, enabling easy migration.","working_principle":"The LC26G module operates by receiving L-band GNSS signals through an external active or passive antenna connected to the RF input. The integrated LNA amplifies weak satellite signals before they reach the RF front-end, which downconverts and digitizes the signals. The baseband processor then correlates the received signals with locally generated PRN codes to identify and track visible satellites across GPS L1 (1575.42MHz), GLONASS L1 (1602.5625MHz), Galileo E1 (1575.42MHz), BDS B1I (1561.098MHz), and QZSS L1 (1575.42MHz) bands. The navigation processor calculates position, velocity, and time (PVT) solutions using trilateration from multiple satellites. EASY technology stores up to 3 days of ephemeris data in internal RAM, enabling quick position fixes without full satellite data downloads. The multi-tone active interference canceller detects and mitigates jamming signals, ensuring reliable operation in noisy RF environments.","pin_description":"
