NEO-6M(GPS)

NEO-6M is a GPS module(GPS-Global Positioning System), is one of the good design modules and it has high sensitivity in indoor applications. It is used to find out the location(Latitude and Longitude) which means it does not give the area names, just provides latitude and longitude values if you search these values in Google maps you can find out the location, or else you need to design a URL with these readings.

GPS module has an inbuilt battery, a memory unit (EEPROM), an external ceramic antenna and its dimensions are 16 x 12.2 x 2.4 mm package. It is configured with UART serial communication with a default baud rate of 9600 bits/sec. The 50-channel u-blox 6 positioning engine boasts a Time-To-First-Fix (TTFF) of under 1 second. The dedicated acquisition engine, with 2 million correlators, is capable of massive parallel time/frequency space searches, enabling it to find satellites instantly.

If you connect this module to the computer with the help of a USB-TTL converter with PUTTY software you can get the latitude and longitude readings, otherwise, you need to interface with the microcontroller and develop a bit of scratch then you can get the readings.

GPS module gives a different type of data formats as shown below, which include location, speed, time, and date.

How to use NEO-6M GPS Module

Requirements:

GPS module(neo-6m) with antenna,
TTL to USB converter
computer.

Software:

Putty / Flash magic

Make the connections as follows
