| GPS adalah singkatan bagi Global Positioning System. GPS Receiver adalah alat yang memberikan maklumat kedudukan dan masa di mana-mana sahaja berada di atas muka bumi.
Di atas adalah pandangan atas dan di bawah adalah pandangan bawah GPS Receiver SKGPS-53.
GPS Receiver memberikan data UART dalam bentuk NMEA 0183 Protocol. NMEA protocol memberikan setiap data bermula dengan simbol ‘$’. Kod selepas ‘$’ adalah ‘GP’ untuk GPS kemudian diikuti kod-kod seterusnya. Antara kod-kod yang terdapat dalam GPS adalah:
| GGA | Global Positioning System Fix Data |
| GSA | GNSS DOP and Active Satellites |
| GSV | GNSS Satellites in View |
| RMC | Recommended Minimum Navigation Information |
| VTG | Course Over Ground and Ground Speed |
| GLL | Geographic Position – Latitude/Longitude |
| ZDA | Time & Date |

Haryn, to transmit gps data you need another UART pin. Can use PIC with more than 1 UART or use multiplexer/demultiplexer. After you get it, you can connect to any wireless ex gsm, xbee, bluetooth and wifi. I have done combine GSM and GPS.
Hi there shahrul..great explanation.tq..1 gt a doubt, is there any way we can transmit the gps data through a wireless device?..for example using a Bluebee and interface it with computer so that we can view the gps coordinate in the computer?if yes,could you please explain a bit detail? thanks in advance friend..good day.
yc, I don’t know your problem. Do more.
Im doing similar project. When I try to display the NMEA data onto the LCD it only give me rubbish value. Initially I tot its the fault of my gps module so I checked using RS232 and discover that there was no problem at all (with gps module). What could be my potential problem? What I tot is my microcontroller canot syncronize with my gps. My GPS is 9600bps. I set my SPBRGH to match 9600 using the formula given. Do I need to measure the real baud rate of my crystal and put it into the equation?
w/salam, Khai. Saya pun x tahu, belum cuba lg.
Assalamulaikum, En.Shahrul.. Sy nak cuba calculate jarak pergerakan (straight line) dlm 2km, so GPS receiver ini boleh x diprogram untuk kira jarak tersebut n klu bleh kita kena guna data ape GGA @ VTG or ape?.. Tq
muizz, arduino guna serial je. Saya akan tunjukkan menggunakan chipKIT saja nanti.
bagaimana pula jika tidak menggunakan pic spt yg ditunjukkn sebaliknye menggunakn arduino. boleh beri sedikit tunjuk ajar?
Jack Hu, the schematic is easy. Just connect 5V, GND and TX. Refer to the GPS Manual.
