how to separate two GPS signal in one COM Port

[Brian_Beal]

The filter I was thinking of would consist of averaging a certain number of readings.  You could also ignore certain points if you know it is not possible that they are correct.  You could determine that by the location of a reading being outside of the travel abilities of your crane.  You could also ignore adjacent readings if the distance moved is not possible within a certain timeframe.  You will truly want to do as much filtering in the Novatel unit as possible.  This is the easiest place to do it.

I just want to share the reply from the GPS maker,

" Even if the antenna is in the stationary mode, the position will still wobble inside the certain accuracy radius. This movement is unpredictable and will not stay on the same point over time. This is due to atmospheric error, orbital error, receiver clock error etc. The spec sheet of each receiver shows the accuracy of horizontal position (CEP) which equivalent to the accuracy radius."

For my GPS receiver the accuracy radius is 0.45m. That means the data i am seeing are the update unpredictable data within the 0.45m radius.

I was wondering if anyone would mind reposting the llb files that Jason posted in a previous post in LV 7.0?  I can't seem to open them, since they are for 7.1. 

I'm just interested in looking over the vi's to see if they can give me further ideas to explore with my own GPS.

Thanks...

Have a nice day.

Hi Bong,

Can you re-up these one more time in 7.0?  They seem to be 7.1 and I can't open them.

Thanks again.

I am up to 8.0 now, but send me an email, and I can send some screen captures for you to look at.

Hi I'm new to labview. I would like to know if it is possible to add a function to garmin comm.vi such that by pressing a button, a text file will be created with the current time, altitude, latitude and longitude. Thanks

[Wiebe@CARYA]

If you have the current time, altitude, latitude and longitude, simply convert it to string with the format into string function.


Then, use the file I/O functions (Write Text File) to save the string.


You can also use format into file, but it's a bit more complicated.


Regards,


Wiebe.
