1. I am interested in making a project in which data received from the GPS is transmitted to distant end using a radio. Please also let me know how I can interface it with Atmega32 and further with radio.

Welcome to the board,

First of all you need a GPS module, and RF module for communication, both comes with Serial USART communication as well as I2C support depend upon module, You have two connect these odule with Microcontroller.

If you are using I2C Communication than ATmega32 will be enough, as you have to make ATmega32 as I2C master and both module as Slave I2C device. However if you are using USART module than one thing is need to be remember. ATmega32 has one hardware USART and ATmega324 has two hardware USART. Its better to use two seperate hardware USART. But you may use ATmage32 as well, for this you have to use one hardware USART and one Software USART by using Interrupt function.

Hope this may help you

You will need a GPS module, microcontrollers, Max232, RF modules and some general purpose components. First Receive data from GPS module and then using the RF transmitter send it to receiver at the other end. To interface GPS with microcontroller, made ground pin of max 232 and serial o/p of GPS modem common. Connect Pin2 of MAX232 to pin 3 of GPS modem and pin 3 of max 232 to pin 2 of modem. you can get a circuit diagram for the same **broken link removed**
 

please search and choose GPS module and RF module as you want. Read the manual and make your design with its. Just for example, in my application, i usually use to RXM-GPS-SR for GPS module, TRM-433-LT as transceiver module and ATMega88. All chips are low power and can be operated by 3VDC battery. If you only want to transmit GPS data, please use transmitter module.
