Gps Module + External Antenna + Waas + Usb

**e_z_street** · 10-05-2004, 08:54 PM

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.

Also check the garmin GPS modules, they are WAAS enabled.

Ok, found the Garmin one:

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

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