wow, GREAT lesson, Paul.... recorded 8 years ago. Today, (26 Jan 2023 ) as I started to research all things, GPS.. specifically looking to understand the data streams.. I backed into your lesson!! How fortuitous. thanks for a most excellent explanation of NMEA Sentences .. God bless you, Brother...
Paul, you are by far the best teacher I have came across so far. I really like how you take the time and effort to explain whats going on, especially on the confusing topics. Thank you!
Thank you for your series of lessons. Whilst you may have the intensions of training high school students, I am aware of several electronic engineers including myself, that learned so much in a short time from all your modules. I live on my yacht, and your lessons on NMEA, GPS and arduino are helping me to connect all my devices together, one i work out the NMEA hardware side of things. Thank you again for your time.
Does not Latitude always and only have 2 digits (90 degrees is North- or South Pole; single digits get leading zero), and Longitude always 3 digits (max 180 degrees, not 200 as you said somewhere half way ;) )? Or is that a different version of the NMEA protocol definition that I'm looking at? A fixed format makes decoding a good step easier... By the way: compliments on your GPS lessons! Easy and clear, even for a "nuts and bolts" mechanical guy like myself :)
I am using a GPS and for a project I'm working on I only need the $GPRMC sentences. I've been able to get rid of all the other sentences available at boot up. Fine. Now my question is: In the $GPRMC sentence I can get 'A' or 'V' as acquiring fixes or not. My project is a clock and only needs the actual UTC time (hour/date). no GPS position needed. So Could I use the 'A' or 'V' conditions to get the UTC time or I must have a fix with the 'A' letter showing ? If the 'V' worked fine for the time/date only I could use it even if I'm having a hard time to get a fix waiting for the 'A' letter to be received.. So 'A' needed or 'A' & 'V' can do ? Thanks.
Hello. A great set of videos but not quite what I'm looking for. I realize this is a few years old now, but I'm trying to set up a simple conversion of NMEA 0183 strings coming from a GPS mapping program that I'm trying to set up a guidance Light bar that will help me with the mobile mapping of an event I set out with way points, roads etc. I have previously just tried to follow the arrow on my map (Tablet) but often it is not very accurate. I thought it would be simple enough to build a light bar similar to what is used in the agricultural industry & us an Arduino to convert the NMEA 0183 strings that my mapping system out puts for autosteer. Surely it can't be that hard, but I think I'm missing something ?? Any wisdom towards this would be greatly appreciated. I will watch this video again I I make sure I am understanding the data but converting it into simple LED's is where I am getting lost. Cheers!!
Hi.Mr paul...I wish all the Good thing in the wold happen to you..may I ask you Sir a question.bugging me since I started watching you lessens .how we can used these converted coordinates from NEMA sentence to control a robot based on arduino here on earth?? thanks alot in advanced
Hi Paul. Thanks for the informative video. I have a question about assisted GPS? Not sure if you would know but I thought I'd give it a shot. Is it possible to get that feature in any GPS such as the ultimate GPS or is that more of a software stack thing enabled with the GPS receiver? I'm guessing it would not be possible in ultimate GPS but wanted to make sure. If I am buying a cellular module and GPS module, I would have to make sure that both these modules have software to enable assisted GPS right?
So, the only reason, for your use of both, the GPRMC, GPGGA sentences, is for the amount of, satellites count, speed, and altitude; everything else is redundant, for your purposes, correct? I am really enjoying your lessons, and only wish they had something more than Estes, like this, back in my day! $GPRMC, $GPGGA $GPRMC, $GPGGA
You're pronouncing it wrong. NEMA is the National Electrical Manufacturers Association. NMEA (The National Marine Electronics Association) is pronounced "Enemy Aye"

Best explanation I've heard in decades!
Excellent video. Gives a great overview of NMEA

thank you for such useful information
Good work!
It helped me with a job using a Arduno Nano and a old Holux GPSlim236, there is still some work to do on my quadopter.
Thank you.

Hi doctor, do you know why everyone pronounce NMEA as "NEMA" ???? this really confuse me

I know I'm writing still the same but this is amazing and perfect work.
Thank you!
@dzeykop, I appreciate the kind words. Glad you are finding these lessoons useful. Thanks.
can i plug out microchip from arduino and connect it outside an external circuit
10 minutes in, how could you be at a latitude greater than 90 degrees?
Can you give us a tutorial about making a speedometer from gps?
Outstanding!!
I know this is an old series but I'm going to do this one. Hardware on the way.
Sir, Can we get the name or id of satellite that sent the gps data ?
please reply its urgent
do you have tutorial of this using android studio?
Valeu
I can contact you privately to ask you some questions about the gps world
