New (14.07.2010) : Sirf-3 chipset instead of MStar.
The CTFGPS-4 GPS receiver features the new well known and reliable Sirf-3 chipset and can be used with any PC/MAC with an USB connector. The receiver has USB-stick shape and because of his shape he is perfectly useable with eg. UMPC or display USB-HUBs. The integrated highly sensitive GPS Aaerial gives you a maximum receiption quality.
The integrated USB-to-Serial bridge eases usage. For installation you only need a small USB driver.

Das Produkt konnte ich leider gar nicht verwerten, weil es zwar als für den Mac tauglich beschrieben war, aber keine Installationsbeschreibung dabei war und auch im Internet nicht zu entdecken war, dass ich es hätte nutzen können. Ich muss Ihnen das Produkt leider zurückschicken mit der Bitte um Gutschrift.
Vielleicht finde ich ja demnächst etwas Passendes.
Viele Grüße
