Hallo
Wer weiss wann , wo und zu welchem Preis es die GPS Card gibt/geben wird?
Wen es interessiert, ich habe hier ein paar Meldungen zu der Card:

After more than a month with the Xtrac technology, I've come to the conclusion that while the sensitivity is truly amazing, unless you live or travel in an area where the reception is very difficult, I wouldn't recommend it for GPS assisted navigation due to the latency inherent to this technology. It might be a case of adapting the existing software solutions, but for now the slow map rotations and delayed turn notification are problematic in a city environment.

SiRF Technology Announces SiRFXTrac High Sensitivity Software to Deliver Accurate Location-Awareness in Challenging Environments
Innovative new software extends operating range of GPS by enabling signal acquisition and tracking in previously inaccessible environments for mobile users
SAN JOSE, CA (October 28, 2002) SiRF Technology, Inc. today unveiled a new high sensitivity GPS software that will extend the operating range in which GPS can be used, dramatically increasing the versatility of GPS-enabled consumer products such as personal digital assistants (PDAs). The result is that mobile consumers can continue using their GPSenabled products in far more locations than ever before possible.
The SiRFXTrac software enables the highly popular SiRFStarIIe/LP chipset to acquire, and continue tracking GPS signals at far lower signal levels than is currently possible with competitive autonomous GPS solutions. For the user, this means that GPS can now be used in environments previously deemed inaccessible environments such as urban canyons, parking garages, dense foliage, multi-level freeways, and, in some cases, indoors. By expanding the number of areas in which GPS can get a position fix, SiRFXTrac will improve existing location-based applications and enable new ones that have been impractical until now.
