LinksPoint's GlobalPoint GPS Serial  receiver is designed for use with vehicle docking cradles for handheld computers. The GlobalPoint Serial GPS receiver features an external GPS antenna and a DB9 interface that is connected directly to the vehicle docking cradle. This allows GPS data to be transmitted to the handheld mobile computer when it is docked in the cradle. The GlobalPoint Serial GPS can receive power from the cradle if available, or through a separate power adapter when used with cradles that do not provide power through the DB9 connection. A variety of power cable options is available. See below.

Chipset Architecture

The LinksPoint GPS attachment uses the SiRFstarIII chip set. This chip set uses a 50MHz ARM7 CPU, which has ample throughput to support extensive user application software and peripherals. The internal satellite signal tracking engine provides highly accurate GPS measurements and differential corrections. This chip set architecture also offers an acquisition accelerator, differential GPS processor, multipath mitigation hardware and satellite-tracking engine. This chip set delivers powerful GPS performance, accuracy, computing power and flexibility.
