QStarz eXtreme: "World's Most Powerful GPS Receiver"

QStarz has just announced the BT-Q818 eXtreme—the self-proclaimed world's most powerful Bluetooth GPS receiver. The 51-channel chipset and 32 hours of use time are impressive, but it's the adjustable update rate that's their claim to fame. The user can choose between 1 and 5Hz updates, with each Hz good for one update per second. In other words, the QStarz eXtreme can sync your position an impressive five times a second, which should be more than enough to placate the most dedicated of car racers and anvil droppers. No word on price or release date at this time. [product via Navigadget]

What I want to know is what the use of 51 channels is when there are only 24 GPS satellites in orbit, plus something like 3 backup satellites.

@Kim98: Maybe it picks up/will pick up the other systems up there? How many channels do each satellite send out? Perhaps it can get two signals from each satellite so if one freq is getting interference, it can get the second signal?

@Kim98: maybe it likes analog too.

So does this mean it will electromagnetically irradiate your body the best?

Awesome. I want to strap 5 to my head.

There is an I-Blue 737 5hz model that already does this, and has been around for a while.

It might even be the same exact thing, except for the different plastic shell design.

not sure powerful is the right term here...

sensitive? accurate? anal retentive?

They are actually well made units and reasonably priced. I have a BT-Q1000, Bluetooth and logging which I use to geotag photos. Software is a bit sketchy, but it works. 32-hours is actual use, not inflated.

Well, I've worked with GPS for over 3 years, and let it just be said that the GPS system is meant to work at 1Hz. Everything above this is interpolated from past positions.
I've worked with a $30k GPS (DGPS RTK) system that had 2.5cm precision, and could update at max 10Hz. It was done using interpolation.
So basically, the 5Hz is obtained _artificially_, and could be emulated on a PC (we would do it up to 20Hz).

@siwu: Stop being smart, say something witty. Your logical post makes me look bad.

@siwu: so if i installed a PC in my car, then run a max of 20Hz *artificially*, i could sync my position at 20X's per second? who knew?

Wish I could sync this with my iPhone's bluetooth.

Hrm... 5Hz isn't exactly new - there are a number of aviation GPS' that claim 5Hz for a while now, even into the glass displays.

I don't know if it's interpolated or if they're actually doing something real...

Is there any software that can do 5 Hz? I think all software is designed to do 1 Hz or has some kind of dead reckoning system.

as kim98 points out, you can't see more than 12 or 13 satellites at a time, so unless it's firmware-upgradable for Glasnoz(?), there's really no point.
