The LC76G is a dual-band L1+L5 GNSS receiver module from Quectel, offering a compelling balance of precision, power efficiency, and cost-effectiveness for UAV navigation. Built on the AG3335M dual-band engine, it provides concurrent reception across GPS, GLONASS, Galileo, and BeiDou on both L1 and L5 frequency bands. The L5 band's advanced signal structure enables improved ionospheric error correction and stronger multipath rejection compared to single-band L1 receivers, yielding a standalone accuracy of 1.0 meter CEP — a notable upgrade for mid-range drone platforms.
Packaged in the industry-standard LCC-24 form factor (12.2 × 16.0 mm), the LC76G is pin-compatible with popular u-blox NEO-series modules, making it a drop-in alternative for existing flight controller designs. The module delivers up to 20 Hz navigation update rates while consuming only 32 mA during continuous L1+L5 tracking — an efficient power profile that extends flight endurance on battery-constrained UAVs. The default 115200 bps UART interface ships ready for immediate connection to common autopilot GPS ports.
A standout feature of the LC76G is its built-in jamming detection and anti-jamming capability. The module continuously monitors the RF spectrum for continuous wave (CW) interference and reports jamming status via standard NMEA messages. Combined with multi-tone active interference cancellation, this makes the LC76G particularly valuable for UAV operations in contested RF environments — a capability that single-band L1 receivers typically lack. The module also supports A-GNSS through Quectel's EASY self-generated ephemeris and server-based EPO data, achieving sub-5-second TTFF on aided cold starts.
