The art of getting good answers lies in asking good questions. Quote from: mwangilbert on Sep 21,pm. Quote from: jurs on Sep 21,pm. Yes, which GPS device are you using with that antenna?

And, like jurs suggested, start with a simple echo program to see what data is being emitted by your GPS device. It's also faster and smaller than the other libraries, which may be important if you are at the limit of your Arduino's RAM or processing speed. It is more complicated "under the hood", but it comes with several example programs and configurations. Is there a way I can do it without libraries? Code: [Select]. Quote from: mwangilbert on Sep 22,am.

I will be trying your tips libraries I am now trying the libraries. First, I would suggest that you decide what information you really need: fix status none, time only, standard, differential [really good! Satellite count and DOPs can tell you how your antenna is doing, though. I can't think of a reason to know the Talker ID. Or any of the other combinations?

I suppose there could be some programmer, somewhere, who thinks he can use it to improve the fix. I'm skeptical. And there's always one guy that shows a text list of satellites being tracked. So I'm not sure why you would save and display this information with an Arduino Whatevs, NeoGPS can parse it all for you.

Deciding what you really need will help keep the RAM, program space and processing time as small as possible. This will also determine which sentences have to be enabled. For example, if you only need time, you would only have to enable the ZDA sentence. Great explanation, thanks! SA means "Selective Avoidance"?Firmware Stream:. This log contains time, position and fix related data of the GNSS receiver.

Instead, it uses a UTC time, calculated with default parameters. When a valid almanac is available, the receiver uses the real parameters.

Here is an example of a NMEA sentence describing time, position and fix related data:. Log header. See Messages for more information. OM v15A. Skip To Main Content. All Files. Submit Search. You are here:. May be different to the number in view xx 10 9 hdop Horizontal dilution of precision x.

OM v15A March Latitude DDmm. Longitude DDDmm. Number of satellites in use. May be different to the number in view. Horizontal dilution of precision. Undulation - the relationship between the geoid and the WGS84 ellipsoid.

Age of correction data in seconds The maximum age reported here is limited to 99 seconds. Differential base station ID.This board is designed for applications that use a GPS connected via the serial ports to the Raspberry Pi such as timing applications or general applications that require GPS information.

NMEA / GPS messages - GPGGA or GPRMC? And what to do in a tunnel?

It is possible to stack additional HAT's on top of this board with a suitable header. GPS's can output a 'pulse per second' for synchronizing the time. We have a breakout for this and aclosed jumper that connects it to GPIO5. However, if you want to place your project in a box, it might not be possible to have the antenna pointing up, or it might be in a metal shield, or you may need more sensitivity.

In these cases, you may want to use an external active antenna. Then connect the GPS antenna to the cable. This tutorial assumes you are using an up-to-date Raspbian install, have access to either LXTerminal or SSH and have an internet connection!

By default, the Raspberry Pi serial port console login is enabled. We need to disable this before we can use the serial port for ourselves. Keep in mind that it can take a long time for the HAT to get a lock, so be patient. For best results make sure the aerial is outside and has direct line of sight to the sky. You can change this or create a new folder if you wish.

Is there any formula? The format for NMEA coordinates is d ddmm. This is for small devices where double values are a problem.

It is done in c code but can be changed to another language easily:. Learn more. How to convert latitude and longitude of NMEA format data to decimal? Ask Question. Asked 4 years ago. Active 2 months ago. Viewed 22k times. NajLinus NajLinus 1 1 gold badge 3 3 silver badges 10 10 bronze badges.

Active Oldest Votes. Yes, NMEA format is ddmm. Thank you Ros Hartigan. Not quite NajLinus, you have the longitude correct, but have not the latitude. The conversion for latitude yields 0. Thank youappreciate you help.

Email Required, but never shown.The sentences were created as a means for marine electronics to all speak the same language, thus enabling digital communication between different devices. They look like this:. Each sentence is referred to as a message and tells useful information about the receiver and its positioning. The output above was obtained from a u-blox CM8P.

Note the contents of each field will be the same for all GGA sentences but minor variations may occur from one GNSS receiver to the next. The first two letters denote the Talker ID, identifying the source of the information. The next three letters define the message content. Some common messages are listed below. Lower numbers indicate a higher confidence level.

Thus, the Blank when DGPS is not used. However, other sentences may be useful, depending on your navigation needs. Below are some great resources I used in compiling this information.
