Enough... I want 5hz

Dwaine · 12-08-2007, 06:22 PM

Is anyone else getting tired of waiting for a pc based gps application to support 5hz updating?

Come on.... This should finally be included in all the software out there.

GPS's sent out typical 1 location (till 3 lines of asci text : possition, speed, sat info, ...) per second.

Serial speed off a GPS is only 2400, doesn't permit more data in a second.

So it's not due to the software but to the hardware (and it need for all vendors to be the same)

They make 5Hz GPS no problem. Thing is nobody need that. Even car manufacturers use 1Hz GPS because it is cheap. They make the images smooth by using speed sensors and turn sensors as well which is all doable via the PC, but then the software would need to support it. And I am sure PC navigation software is mostly used by people who just lug a laptop in there car when driving cross country, not for people with dedicated carpcs, so hooking up a gps puck, speed sensor, turning sensor is a lot more for the average joe, then plug-n-go usb puck.

I want a billion dollars in small, unmarked, non-sequential U.S. bills.

Looks like we're both wanting, aren't we?

I think you mean Canadian bills. They are worth more now.

Make that £'s they are worth far more

But we dont have a GBP key on our keyboards.

And on a laptop without a numpad, ascii codes are of little help.

And why is it the british pound? Shouldn't it be the "british kilogram"? GBKG!

A billion of anything except maybe Mexican Pesos or Italian Lira.

Thank goodness US currency isn't the complete worst on the planet.

Arn't they using the euro € in Italy ?

2k1Toaster · 12-15-2007, 03:00 AM

Yeah they have used euros for a few years. 2002/2003 I think.

But the Venezuelan Bolivar is around 1usd to 2500 bolivar.

I think the turkish lira (old style) used to be 1:1000000 or even 1:1500000

Why settle for 5Hz? "...It estimates the vehicle position and orientation 60 times per second and uses this real-time data, together with the 3-D geographical (route) data, to re-calculate and re-draw..." http://www.laptopgpsworld.com/hardwa...on-system.html

I'm using ALK CoPilot Laptop 10 with a 5Hz BT GPS without any problems. I agree that for navigation, 1Hz is sufficent. I use my 5Hz as part of my datalogging setup during autox and track events where 1 second updates is too slow.

I've recently upgraded to a 10Hz receiver and CoPilot has been working fine with that too.

We have local navi software, wich can update onscreen image as many times per second as hardware can recalculate. Looks helpful, because while driving I cannot look directly to the monitor, but using high fps I can "feel" right turns, distances, work of "autozoom" realtime option etc.

There are some problems in programming such software due to 1Hz gps sygnal. For missing frames we use interpolation and a little bit extrapolation algorythms. Later fps was limited by 5 because streets naming flips too often. Their position was not blocked to leave nice effect of "names follows the streets". It looks like liquid texts dynamically bends along the viewable fragment of the street while driving with closest zooms.

That was good idea (2k1Toaster) to use gyro-odometer sygnals to avoid extrapolation in real-tame navigation software. For example in ublox DR chipsetst you can set custom period of calculation speedimpulses, gyro is sampled by 40Hz and their UBX-protocol is not ASCII, its binary, with flags, crc's etc. The question of adequate navi-software, supported such things is opened for most areas.
