    Gps Module + External Antenna + Waas + Usb

    Just to piggy back off of this post:

    Just purchased Deluo w/external antenna

    This post mentions the Deluo gps unit that has a connector for an external antenna. The only problem with this unit is that it is not WAAS enabled. I would like to use an "all in one" antenna as mentioned in this post:

    All in one GSM/FM/GPS Antenna

    If anybody else is looking, I did find a module that is WAAS enabled, has a connector for an external antenna, and would allow for a serial connection to a pc:

    Can anyone comment on this module or have any recommendations for other modules with similar features?

    (There are many CF and Bluetooth modules that are WAAS enabled and have a connector for an external antenna - I would like to specifically use serial or usb input)

    Thanks

    By the look of it you will need to build a TTL<>RS232 converter, typically based on MAX232 chips. The datasheet says that the GPS output is TTL.

    And of course you will need a +5V regulator, based on 7805 perhaps.

    Ok, found the Garmin one:

    http://www.garmin.com/products/gps15h/spec.html

    It already has serial output. Anybody use this? I'll check on price.


    Lowest price on Froogle - $93.99 (w/o the external antenna)
