I present my summer project to the personal of the CASA project.

GPS device

Ambicom usb-gps receiver:

The gps is connected in a computer via serial port.

Our Goal!

We want to always get accurate and real-time location,
location and positioning of the radars.

Through our software, we can manage remotely from
anywhere via Internet the data received.

Today I present my progress report. And a draft of the GPS application. I discuss some important terms of the GPS, like how the GPS receives data.

Using Hyperterminal

Hyperterminal is a windows program that we can use to view the data  that is received by the computer serial port.


Here's an example of how the program is receiving data: 

How a GPS WORKS?

       GPS works through a network of 24 satellites orbiting the globe at 20,200 km, with synchronized paths to cover the entire surface of the Earth . When you want to determine the position, the receiver is used to automatically locate it at least three satellites in the network, which receives a signal indicating the  identification and the hour in the clock  of each one.

NMEA data example

The gps receives data in the NMEA format.
