Ivory 4 - A compact GPS module with high sensitivity and low power consumption
Ivory 4 is a compact module based on MediaTek's latest MT3339 engine, offering fast Time-to-First Fix (TTFF) and a high sensitivity (-165 dBm) along with an ultra-low power consumption.
Ivory 4 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 easy integration of module, without the need for external components.
Ivory 4 supports SBAS, Anti-Jamming, AlwaysLocateTM, EASYTM, EPOTM, and logger function, and these features can be further extended with our free customization service.
