In this tutorial we will learn how to get GPS data using 3G, 4G/LTE shield.
GPS(Global Positioning System) also known as NavStar indicates the position of an individual on the earth. The Satellites orbiting around the earth sends precise details of their positions at a regular interval of time. Once information are received by a GPS receiver, a GPS receiver can pinpoint the location.
There are also navigation systems which support in their in specific regions like GLONASS provided in Russia.
For this tutorial we will need
a. Raspberry Pi
b. 3G, 4G/LTE Shield
c. 3G, 4G/LTE module (for 3G UC20 and for 4G EC25 is used)
d. PCB Mobile Antenna (2x)
e. GPS Antenna
Here it goes
Previously we have used GPRS shield to establish internet connection. Now we will use 3G, 4G/LTE shield for PPP internet connection. In order to make a 3G and 4G connection we will need to use Quectel UC20 and Quectel EC25 modules respectively.
As this tutorial is for 4G PPP Internet connection, we will use Quectel EC25, which is a series of LTE category 4 module optimized specially for M2M, IoT and multimedia applications. Due to rich set of protocols, industry-standard interfaces and abundant functionalities extend the applicability of the module ti a wide range of M2M and IoT applications such as industrial router, industrial PDA, rugged tablet PC, video surveillance and digital signage.
