TinyGPS

A Compact Arduino GPS/NMEA Parser

TinyGPS is designed to provide most of the NMEA GPS functionality I imagine an Arduino user would want – position, date, time, altitude, speed and course – without the large size that seems to accompany similar bodies of code. To keep resource consumption low, the library avoids any mandatory floating point dependency and ignores all but a few key GPS fields.

Usage

To use, simply create an instance of an object like this:

#include "TinyGPS.h"
TinyGPS gps;

Feed the object serial NMEA data one character at a time using the encode() method. (TinyGPS does not handle retrieving serial data from a GPS unit.) When encode() returns “true”, a valid sentence has just changed the TinyGPS object’s internal state. For example:

#define RXPIN 3
#define TXPIN 2
SoftwareSerial nss(RXPIN, TXPIN);
void loop()
{
  while (nss.available())
  {
    int c = nss.read();
    if (gps.encode(c))
    {
      // process new gps info here
    }
  }
}

You can then query the object to get various tidbits of data. To test whether the data returned is stale, examine the (optional) parameter “fix_age” which returns the number of milliseconds since the data was encoded.

long lat, lon;
unsigned long fix_age, time, date, speed, course;
unsigned long chars;
unsigned short sentences, failed_checksum;

// retrieves +/- lat/long in 100000ths of a degree
gps.get_position(&lat, &lon, &fix_age);

// time in hhmmsscc, date in ddmmyy
gps.get_datetime(&date, &time, &fix_age);

// returns speed in 100ths of a knot
speed = gps.speed();

// course in 100ths of a degree
course = gps.course();

Statistics

The stats method provides a clue whether you are getting good data or not. It provides statistics that help with troubleshooting.

// statistics
gps.stats(&chars, &sentences, &failed_checksum);

chars – the number of characters fed to the object
sentences – the number of valid $GPGGA and $GPRMC sentences processed
failed_checksum – the number of sentences that failed the checksum test

Integral values

Values returned by the core TinyGPS methods are integral. Angular latitude and longitude measurements, for example, are provided in units of millionths of a degree, so instead of 90°30’00″, get_position() returns a longitude value of 90,500,000, or 90.5 degrees. But…

Using Floating Point

…for applications which are not resource constrained, it may be more convenient to use floating-point numbers. For these, TinyGPS offers several inline functions that return more easily-managed data. Don’t use these unless you can afford to link the floating-point libraries. Doing so may add 2000 or more bytes to the size of your application.

float flat, flon;

// returns +/- latitude/longitude in degrees
gps.f_get_position(&flat, &flon, &fix_age);
float falt = gps.f_altitude(); // +/- altitude in meters
float fc = gps.f_course(); // course in degrees
float fk = gps.f_speed_knots(); // speed in knots
float fmph = gps.f_speed_mph(); // speed in miles/hr
float fmps = gps.f_speed_mps(); // speed in m/sec
float fkmph = gps.f_speed_kmph(); // speed in km/hr

Date/time cracking

For more convenient access to date/time use this:

int year;
byte month, day, hour, minutes, second, hundredths;
unsigned long fix_age;

gps.crack_datetime(&year, &month, &day,
  &hour, &minute, &second, &hundredths, &fix_age);

Establishing a fix

TinyGPS objects depend on an external source, i.e. its host program, to feed valid and up-to-date NMEA GPS data. This is the only way to make sure that TinyGPS’s notion of the “fix” is current. Three things must happen to get valid position and time/date:

You must feed the object serial NMEA data.
The NMEA sentences must pass the checksum test.
The NMEA sentences must report valid data. If the $GPRMC sentence reports a validity of “V” (void) instead of “A” (active), or if the $GPGGA sentence reports fix type “0″ (no fix) then those sentences are discarded.

To test whether the TinyGPS object contains valid fix data, pass the address of an unsigned long variable for the “fix_age” parameter in the methods that support it. If the returned value is TinyGPS::GPS_INVALID_AGE, then you know the object has never received a valid fix. If not, then fix_age is the number of milliseconds since the last valid fix. If you are “feeding” the object regularly, fix_age should probably never get much over 1000. If fix_age starts getting large, that may be a sign that you once had a fix, but have lost it.

float flat, flon;
unsigned long fix_age; // returns +- latitude/longitude in degrees
gps.f_get_position(&flat, &flon, &fix_age);
if (fix_age == TinyGPS::GPS_INVALID_AGE)
  Serial.println("No fix detected");
else if (fix_age > 5000)
  Serial.println("Warning: possible stale data!");
else
  Serial.println("Data is current.");

Interfacing with Serial GPS

To get valid and timely GPS fixes, you must provide a reliable NMEA sentence feed. If your NMEA data is coming from a serial GPS unit, connect it to Arduino’s hardware serial port, or, if using a “soft” serial port, make sure that you are using a reliable SoftSerial library. As of this writing (Arduino 0013), the SoftwareSerial library provided with the IDE is inadequate. It’s best to use my NewSoftSerial library, which builds upon the fine work ladyada did with the AFSoftSerial library.

Library Version

You can retrieve the version of the TinyGPS library by calling the static member library_version().

int ver = TinyGPS::library_version();

Resource Consumption

Linking the TinyGPS library to your application adds approximately 2500 bytes to its size, unless you are invoking any of the f_* methods. These require the floating point libraries, which might add another 600+ bytes.

Download

The latest version of TinyGPS is available here: TinyGPS13.zip

Change Log

initial version
<< streaming, supports $GPGGA for altitude, floating point inline functions
also extract lat/long/time from $GPGGA for compatibility with devices with no $GPRMC
bug fixes
API re-org, attach separate fix_age’s to date/time and position.
Prefer encode() over operator<<. Encode() returns boolean indicating whether TinyGPS object has changed state.
Changed examples to use NewSoftSerial in lieu of AFSoftSerial; rearranged the distribution package.
Greater precision in latitude and longitude. Angles measured in 10^-5 degrees instead of 10^-4 as previously. Some constants redefined.
Minor bug fix release: the fix_age parameter of get_datetime() was not being set correctly.
Added Maarten Lamers’ distance_to() as a static function.
Arduino 1.0 compatibility
Added satellites(), hdop(), course_to(), and cardinal()
Improved precision in latitude and longitude rendering. get_position() now returns angles in millionths of a degree.

Acknowledgements

Many thanks to Arduino forum users mem and Brad Burleson for outstanding help in alpha testing this code. Thanks also to Maarten Lamers, who wrote the wiring library that originally gave me the idea of how to organize TinyGPS. Thanks also to Dan P. for suggesting that I increase the lat/long precision in version 8. Thanks to many people who suggested new useful features for TinyGPS, especially Matt Monson, who wrote some nice sample code to do so.

All input is appreciated.

Armand Aanekre- have you tried going into SoftwareSerial and up your buffer to 128?

Mikal- RE: Locosys ‘s LS20031 GPS unit everybody has had trouble with- I finely got it working with no check sum errors– I did have to use a logic Voltage level converter to talk to the 3.3V part from my 5V Uno. I am using the I2C Level Converter from http://www.dsscircuits.com/i2c-level-converter.html with no problems. Don’t let the I2C spook you, it works great with Serial Communication- see Wayne Truchsess comment at the bottom of that last HTML page.

What I did was to write the following >>

#define PMTK_SET_NMEA_OUTPUT_RMCGGA “$PMTK314,0,1,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0*28\r\n” // turn on GPRMC and GPGGA —– TinyGPS only uses these two, all others can be turned off

#define PMTK_SET_NMEA_UPDATE_1HZ “$PMTK220,1000*1F\r\n” // Every 1000ms (1Hz)

#define PMTK_Q_RELEASE “$PMTK605*31\r\n” /* Query FW release information — MTK-3301s send firmware release name and version – Note: not sure of accuracy of this information */

void setup()
{
Serial.begin(115200);
nss.begin(57600); // LS20031 baud- 57600
while (!nss.available()){}
nss.print(PMTK_SET_NMEA_OUTPUT_RMCGGA); // $GPxxx Messages
nss.print(PMTK_SET_NMEA_UPDATE_1HZ); // messages 1 times a second
nss.print(PMTK_Q_RELEASE); // ——————————————————This is not necessary for things to work
Serial.print(“Testing TinyGPS library v. “); Serial.println(TinyGPS::library_version());

I am not showing all the #define examples here do to I just want to show what I did to get things working. I set up a full test bed of all the NMEA_OUTPUT types and sent the output directly to the Arduino’s IDE Monitor. It gave me a better over view of how the LS20031 works. I also learned that a lot of these sentences will work for other GPS’s too.
In addtion to that, I learned when you are starting to get bad check sums and NMEA sentences, look to see if your /n/r is getting overwritten. Also when you see that, most of the time it has to do with the end of the NMEA being overwritten.
One other thing I have discovered is when you are running I2C (Pin 4, and 5 on the Uno) for some other part using I2C with SoftwareSerial (2, and 3 on the Uno) talking to the GPS (two different programs, with two different parts- on the same Uno), it can cause timing issues with SoftwareSerial’s rx &tx. NO- I am not talking about hooking the GPS up to I2C or the Serial to a I2C part. I am talking about internal timing issues with SotwareSerial and the I2C timing hardware can cause random check sum errors. Also people who are using DHT Temperature and Humidity sensors can also wind up with problems do to cli() and sei() disabling global interrupts. There is a work around for these people but right now I am not sure how to do it.

Oh- the preceding modification to your TinyGPS example worked like a charm at 57600 baud- I have had it working for over 8 hours with no check sum errors.

Hi there,

I’m using your TinyGPS library in a car tracking project. I’ve noticed that sometimes it leaves the negative sign off the latitude (I’m the Northern hemisphere so I don’t know if it would do the same for the longitude)

Any ideas?

Thanks!!

Hello, Mikal. I want to try out your library without any GPS device. Could you give me some example command to feed the code for “simple_test”? I am trying to input some proper NMEA commands but the response goes just like that

CHARS=0 SENTENCES=0 CSUM ERR=0
CHARS=0 SENTENCES=0 CSUM ERR=0
CHARS=0 SENTENCES=0 CSUM ERR=0
CHARS=76 SENTENCES=0 CSUM ERR=0
CHARS=76 SENTENCES=0 CSUM ERR=0

So could you please tell me what am i doing wrong?

I just want to test your “simple_test” sketch without any real gps device. Thanks

Thanks for the great work on tinyGPS! This saved me much time with parsing and course/distance. I would make a suggestion to change the floating point methods to doubles instead of floats. Most newer GPS units have accuracy (CEP50) down to 2-3m. The long in get_position has enough precision to get to 0.185m (1/10,000th of minute). But, the float with arduino only goes to 4 positions right of decimal depending on your longitude location. So, you get max accuracy to 11.1m with decimal degrees in a float (1/10,000 of a degree). AVR-based arduinos will still be limited to this because double=float. But, the new Due and ARM-based arduino-like boards implement a true double. Using double would let the floating point side achieve the same accuracy while only costing only a few more bytes of mem.

Firstly thank you for such a great help.
Iam trying to link postcode to this code. the idea behind is i have a file(csv) of the postcodes of a specific area with their long/lat. I want to include those postcodes when the gps get a fix that specific long/lat.

Postcode can be written in StringArrays, this might eliminate the use of sd card.
If you can help, would be highly appreciable.
thanks you
Mikal

@Faaz,

Does your postcode database show the boundaries of each postcode area, or just a single central point? How important is it to precisely map a given point to the correct (and not just a nearby) postcode?

Hi Mikal, I am trying to make an NMEA to SeaTalk protocol converter for GPS specifically, and started using your excellent library. I understand the present version decodes GGA and RMC sentences. I need to get “Fix Quality” from the GGA sentence, how do I do that?

I also need GSV and MSS sentences, so I kindly ask if you can consider to include those in the next release..
Thanks!

@Göran,

I’m working on a new version of TinyGPS now that will allow you to access an arbitrary field in an arbitrary sentence. Thanks for the prod. That will help me get it done fast.

I have an Arduino UNO R3 and an Adafruit GPS shield (their latest version). I used their data logger example and everything works but the data is sent to the SD card as a continuous text file. I like the Tiny GPS code and I’ve been trying to get it to work but I cannot read a sentence. I’m using software serial and this shield sets up a serial port on pins 8,7 of the R3. I’m changing the pin designation to 8,7 in your test_with_gps_device and never get data. The receiver does have a lock indication and works great with Adafruit code. Any hints would be appreciated.

I have a wise clock 4 board w/ atmega 1284p, gpsBee and dual 32×16 sure LED boards. I’m having a problem getting data from the gpsbee. I believe it’s a pin assignment or baud rate problem. The static example runs fine but when I try the test_with_GPS_device I get not data from the gps. Any thoughts or help would be greatly appreciated I’m new arduino but been programing along time.

Hi..Is there any problem if I want to use only the RMC sentence,the other one been stopped for transmission by the GPS unit itself? Also, another question for you…I want to integrate the Tiny in a sketch containing also the Time library and a DS1307 (DS3231 most probably…).In fact, is about a clock build around GPS,but having a DS as backup for the “blackout” receptions of GPS…This clock drives a finite state machine, so I want to be “time-lost-proof”..But I want to know how to manipulate the variables declared in both libraries for time and date, to be able to load the correct time into DS..? Needless to say that I’m total newbie in C++,assembler beeing my “native” language and this only for Microchip…Best regards…

Yes it shows the boundaries from the lag/lat.

Postcode Latitude Longitude Easting Northing

AL10 0AA 51.764308 -0.226194 522507 208780

AL10 0AD 51.773475 -0.218732 522997 209812

it shows like this, now can i get the postcode from the fix i get from the gps? and i dont want big file just few post codes, less than 5 even.

Mikal

11 years ago

Phil, are you sure any data is getting to TinyGPS? Can you prove that you’re calling tinygps.encode()? If not, there’s probably a wiring problem. If so, then I would guess that there is too much delay in calling encode and the serial buffer overflows.

@Mr.C,

While TinyGPS does process both the RMC and GGA sentences, it does not depend on having both. That is, if your device is transmitting only RMC sentences, that’s ok. If you are just using the RMC sentence, you’ll lose fields like HDOP and Altitude, but it sounds like that’s ok since you’re just using the time/date components, right?

I would just repeatedly encode() the serial stream and call crack_datetime() to extract the date and time. Make sense?
Peter

Thanks for a very nice Library, this is very easy to understand and every think works so easy.
but can you maybe tell me how to chance the updating time from the GPS, its only update every second, but can you gets the GPS updating every 0.1 second

Mikal

11 years ago

@Peter,

I suspect that most modules that update once per second by default cannot increase their update rate. 10 Hz modules probably have this capacity, but in any case, such a feature is well beyond the purview of TinyGPS. TinyGPS is agnostic to device-specific details; its goal is strictly to parse NMEA sentences. You might consult your device manual.
Mikal

11 years ago
@Vinnie,

I’m afraid TinyGPS only understands universal time — the “music of the spheres”. :) If you want to calculate UT+4:00, you’ll have to do it manually. If you’re just interested in the time part, it’s not too hard:
```
hour = (hour + 4) % 24;
```
It gets a little more complicated if you also want to calculate the correct date.
flegmatoid

great library. Couple observations / requests:
- allow configuration of “distance_between”. One might want setting earth radius to also include elevation above the sea level, resulting in 10-20 cm difference. One might also like to include altitude in this calculation, resulting in 10-20 meter difference at 10km – 20km altitudes. Or maybe it would make more sense to automatically include GPS data to adjust the accuracy of calculations?

I use Tiny GPS for a long time and everything goes well.
I would like to know how to decode the following information with this library:
(1) The number of satellites.
(2) The meaning of coordinates North or South.
(3) The quality of the signal.
I have test with the Adafruit_gps.h library and is easily obtained this information.

Mikel,
It would be very handy to include maidenhead GRID locator built into TinyGps. I am a ham radio operator and use grids during my contact. I’m new to Arduino and have read a lot on GPS with the Arduino but parsing to grid “square” (as we call them) is not explained so I can understand it. Normally the grid square is something like EM96ft which is my grid locator. You are probably familiar with them. It would invaluable to hams that operate mobile during contests.
Thanks,

My gps returns valid info at $GPRMC, but gps.encode() returns false…
Is there any solution you might think?
Also I have one question, gps.encode() takes one by one character, so how the hell does it check if it is valid?From the letter “V” that comes in NMEA info?
