LC79H Evaluation Board Description
Quectel LC79H is an ultracompact dual-band, multi‑constellation GNSS module that concurrently receives GPS, GLONASS, Galileo, BDS, and QZSS signals. It integrates AGNSS and can receive SBAS broadcasts to deliver fast time-to-first-fix (TTFF) and reliable, high‑performance positioning.
LC79H Evaluation Board Features
- Dual‑band reception (L1 + L5): Concurrent tracking on both bands mitigates multipath effects in deep urban canyons and improves positioning accuracy compared with L1‑only modules.
- Multi‑constellation support: GPS, GLONASS, Galileo, BDS, QZSS for enhanced satellite availability and robustness.
- Integrated AGNSS and SBAS support: Faster TTFF and improved performance in challenging environments.
- Embedded LNA and SAW filter: Allows direct connection to onboard patch antennas for lower cost and lower power design.
- Advanced low‑power management: Optimized for power‑sensitive and battery‑powered applications.
