Anyways, I waited and then my GPS module started giving me the exact latitude and longitude values. GSM and GPS interfacing with Arduino: All the electronics are powered up using a 5Volts regulated power supply, make sure the power supply is around 2A. The RXD and TXD pins of the GSM Sim900A module are connected with the Arduino pins D8 and D7. I too would like a dedicated GPS module or even the ability to pair with a dedicated bluetooth GPS unit, as well. The phone apps, both android and iPhone, mostly sorta work, but will stop working randomly, and need you to do various annoying procedures to get it working again, etc. 708 gps module mobile phone products are offered for sale by suppliers on Alibaba.comAbout 5% % of these are gps tracker, 2%% are wireless & rf modules, and 1%% are navigation & gps. A wide variety of gps module mobile phone options are available to you, You can also choose from odm, gps module mobile phone, Armed with the drive test results, Antenova set out to go one step further and design a complete GPS navigation module suitable for use in a mobile phone handset. One of the major problems was to keep GSM and UMTS transmissions from the handset out of the GPS receiver because the signals may only be 10% apart in frequency (GPS signals are Circuit diagram of the GPS- and GSM-based vehicle tracking system is shown in Fig. 2. It is built around Arduino Uno board (BOARD1), 16×2 LCD (LCD1), GPS module, GSM module and a potmeter (VR1). Working of the circuit is very simple. To operate the circuit, you need to follow the steps given below: Fig. 2: Circuit diagram of GPS- and GSM-based I'm working on some GPS tracking apps on Android tablets. We found out that depending on the type of phone / tablet we use, we can have results ranging from really accurate to really bad. Those tests were conducted on the same track, with GPS only location - so I'm pretty sure the GPS chip quality is of great importance in those results GPS Definition and How GPS Works. GPS, aka Global Positioning System, is a satellite-based system consisting of a minimum of 24 satellites. These satellites orbit Earth at an altitude of about 12,500 miles (20,000 km). It works 24*7 across the globe regardless of the weather conditions. Several researchers have produced their works on vehicle security by using microprocessors, ARM processors [9] Arduino board as a control circuitry and communication using GSM/GPS module [10]- [15 .
