BC-307 SiRF GPS
Description
This is a very nice CF GPS device, especially suited for Linux hosts. Unlike many recent GPS cards, it is a complete receiver on a card. An increasing number of CF, PCMCIA, USB, Bluetooth, etc devices only impliment part of the receiver system in the device, leaving some(or most) signal processing to be done in the “driver” on the host device like the notorious Winmodems.
