Re: Miniature GPS module with 10Hz update rate

Un bel giorno Mook Johnson digitò:

> Do you guys thin that a 5 or 10Hz GPS module exists?

As I've written, u-blox (www.u-blox.com) sells low-cost 4-Hz GPS modules,
they cost around 100$. If you need more speed, be prepared to spend a lot
more (ten times minimum). Look for example Thales Navigation
(www.thalesnavigation.com), they have GPS modules up to 20 Hz.

Other links (but I haven't used their modules - by the way, someone has?):

www.navtechgps.com: modules up to 25 Hz (or 50-Hz raw data);
www.novatel.com: modules up to 20 Hz.

No, reacquisition time is the time needed to restart the acquisition after
a "short blackout" (10-30 s), e.g. when you enter a tunnel.

It looks like a 1 Hz model.
