GNSS With Antenna
Ladybird 3 - Low-power GPS Patch module
Ladybird 3 is a compact antenna module built based on MediaTek's latest MT3339 engine, offering fast Time-to-First Fix (TTFF) and low power consumption. Ladybird 1 comes embedded with a well-tuned and optimized 16 x 16 mm GPS Patch Antenna that offers excellent performance, and relieves the developer of Antenna integration.
Ladybird 3 incorporates high-quality components that are vital for reliable performance. These include an additional-LNA, SAW-Filter, TCXO, RTC Crystal, and power management design, all of which allows makes module integration easier.
Ladybird 3 supports SBAS, Anti-Jamming, AlwaysLocateTM, EASYTM, EPOTM, and logger function, and these features can be further extended with our free customization service.
