    Question

    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

    Question Can it be used with high speed railway?

    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.

    Regards

    Sougata
