The GPS module WD-G-ZX4120 is a high sensitivity ultra low power consumption cost efficient, compact size, plug & play GPS module board designed for a broad spectrum of OEM system applications. This product is based on the proven technology found in other our 16 channel GPS receivers and NEMERIX chipset solution.

The GPS module receiver will track up to 16 satellites at a time while providing fast time-to-first-fix and 1Hz navigation updates. Its far reaching capability meets the sensitivity & accuracy requirements of car navigation as well as other location-based applications, such as AVL system. Handheld navigator, PDA, pocket PC, or any battery operated navigation system.

The WD-G-ZX4120 design utilizes the latest surface mount technology and high level circuit integration to achieve superior performance while minimizing dimension and power consumption. This hardware capability combined with software intelligence makes the board easy to be integrated and used in all kinds of navigation applications or products. The module communicates with application system via RS232 (TTL level) with NMEA0183 protocol.

Hey Lester,
What is power consumption in low power mode, and reacquisition time? I see full power specs @ 27 mils, but no data on power save mode. I don't to want power down totally, because I can't afford to wait 90 seconds.

Thanks,
Ron

Hi,

I would just like to know if it would be reliable and practical to use this GPS module in a train with an average speed of 150Kms / hour. What about external antennae ? Finally, would you ship it to India.
