Description

The ATR0640 GPS chipset is based on GPS technology licensed from Thales Navi­gation, a market leader in the GPS industry.

To ensure the ATR0640 chipset is right for your application, Atmel offers a low cost
evaluation kit. The ATR0640-EK evaluation kit comes in a sturdy carrying case and
provides all the tools necessary to evaluate the capabilities and performance of the
ATR0640 chipset.

Preliminary

5105A–GPS–06/05

The GPS evaluation board is housed in a ruggedized plastic enclosure that can easily be used
for bench characterization or driving over the road. LEDs are visible to monitor the current sys­tem state. Data is transferred via an RS232 serial cable from the evaluation board to the serial
port on your PC via NMEA formatted messages. Every system comes with firmware already
loaded into the receiver, ready to plug and play. A 12V DC input is all that is required to power
the system.

Evaluation Board with Cover Removed

To evaluate the performance of the system, software is provided to monitor all aspects of the
system operation in real-time or by reviewing a data-logged file of a previous trip for later analy­sis. The graphic display shows information such as satellite tracking, strength of signal, position,
velocity and time.
