The LC29H series can track L1+L5 dual-frequency and multi-GNSS signals, reducing multipath effects in urban canyons and improving positioning accuracy while maintaining low power consumption.
General features of the LC29H series include:
- Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards, Jetson Nano.
- Supports simultaneous tracking of L1+L5 dual-band satellite signals, reducing multipath effects in urban canyons and improving positioning accuracy.
- Supports concurrent receiving of multi-GNSS systems (GPS, BDS, GLONASS, Galileo and QZSS) while maintaining low power consumption.
- Built-in low noise amplifier and acoustic surface filter to realize -165dBm high sensitivity and enhance anti-interference performance.
- Supports multi-frequency active interference cancellation, effectively suppressing or eliminating narrowband signal (WiFi/2/3/4/5G) interference to ensure navigation accuracy.
- A-GNSS (Assisted GNSS) support, reducing the time to first fix (TTFF) with cold start when powered on to 5 seconds.
- Support QGNSS software, easy to set various module functions.
- Onboard battery holder, supports ML1220 rechargeable cell, for preserving ephemeris information and hot starts.
