Topic: willing to pay for solution- Save initial GPS data in order to compare with sub  (Read 1 time) previous topic - next topic

Hello,

I am trying to write a code that saves the first good fix (if sats are 6+, hdop is < 1.5 etc) in order to compare it with subsequent location in order to measure the distance between two points.

I am willing to pay for the solution or pay for a tutorial on how to do this on my own.

All the best,

Yannis

Parse GPGGA and save data if conditions are met? Is that it? I may actually have code that does that already IIRC.

I cannot understand what BESTPOS is
I am willing to pay for the solution.
Please see my code here: https://forum.arduino.cc/index.php?topic=706894.msg4771384#msg4771384

Kind regards,

IMO it's a question of what your GPS/GNSS receicer supports - just like any other "standard", YMMV :)

Dear community, is there anyone out there willing to help me with my project?

Doing what you're asking here isn't difficult. You mentioned in your other thread though that you're looking for centimeter accuracy, which you won't get with regular GPS hardware. Is it still worth doing if the accuracy is in the three to fifteen meter range?

cedarlakeinstruments

OK. Let's nail this down.
Is your only requirement to record the first GPS lat/long position from a serial NMEA sentence stream when either the number of satellites locked is greater than or equal to 6 or the hdop is < 1.5?

If so, where do you want this data saved to?

Hello,

I am new to arduino and coding.
With the help od Idahowalker (user) from the forum I managed to write some code.
I want to create a device that measures the distance with gps.
First thing I have to do is to save a good fix and then compare it with the lat/lon from the raw readings in order to calc the distance in meters.

Please see code:

This is what you want to do:

This is you saying how you want to do it.

If you're asking for help, it's best to stick with "this is what I want to do." As soon as you start saying how you think it should be done, that muddies the waters. e.g., I have no idea what you mean by "the raw readings."

OK,

I am sorry about that. I would like to create a distance measuring device that uses gps for measuring.

Hello,

I would like to use it for distances up to 10 meters if possible with the best possible accurancy. 
I know about ntrip (I dont know if there is a better way) but since I have invested in buying the ublox neo 6m module its fine to go with the 2.5 m accurancy for now.

And you are sure that a measuring tape won't solve your problem?
