These low power and low cost modules are 20 channel GPS receivers in compact (18mmx18mm) SMD form.
<p>With a few external components, GPS capabilities can be added to electronic devices at low cost.
</p>
<p> <ul><li>New Enhanced Power saving modes</li>
<li>Improved Tracking capabilities</li>
<li>Low cost</li>
<li>18mm x 18mm</li>
<li>Integrated RF connector supports external active antenna</li>
<li>RF signal may also be routed to pin 1</li>
<li>Low Power</li>
<li>High Sensitivity</li>
<li>FCC /CE approved</li>
</ul>
</p>
<p>
Capable of 18,000m altitude, and 515m/sec maximum measurements, accuracy is to within 2.2m horizontal. Horizontal velocity accuracy is within 2.0m/s.
</p>
<p>
Output is in NMEA -0183 ASCII, baud rates of 4800, 9600 and 19200, with protocols including GGA, GSA, GSV, GGL.
</p>
<p>Typical applications are Hand-held Devices for Personal Positioning and Navigation
PDA, Pocket PC and other computing devices
Fleet Management / Asset Tracking
AVL and Location-Based Services.

<br><br>Benefits claimed by Atmel include:
<ul> <li>Offers hardware security, which is superior to any software solution
<li>Combines hardware security with key diversification, therefore delivering a superior security solution
<li>A hardware security solution makes attacks non-trivial
<li>Key diversification scheme limits any attack to only one unit
<li>Shorter application development cycle time
<li>Atmel is #1 in hardware security
</ul>
<p>The underlying radio system is based on ISO1443-B, and is royalty free. A range of up to 10cm is typical.
</p>
<p>For example, an AT88SC02040CRF can have a range of 8-10cm implemented as a smart card, 1-3cm implemented as a 17mm diameter RFID tag, and 10-15mm as a 10x20mm RFID tag.
</p>
Typical applications are:
<ul>
<li>Production Authentication
<li>Public Transportation
<li>Anti-Cloning
<li>Driving License
<li>Track and Trace
<li>E-Purse
<li>Energy Meters
<li>Health Cards
<li>Campus Cards
<li>Logistics Management
<li>Secure Access Control
<li>Anti-counterfeiting
<li>Identification
<li>Insurance Cards
</ul>
