Gps on ubuntu

I'm trying to get a cheap, generic USB GPS receiver to work on Ubuntu Hardy Heron.

I'm not sure what software to use and I'm not sure if how to configure the device. Here's what happens

Connect gps device

Sep 14 17:39:50 stinkerbelle kernel: [ 3692.418097] usb 4-1: new full speed USB device using uhci_hcd and address 3
Sep 14 17:39:50 stinkerbelle kernel: [ 3692.445968] usb 4-1: configuration #1 chosen from 1 choice
Sep 14 17:39:50 stinkerbelle kernel: [ 3692.447559] pl2303 4-1:1.0: pl2303 converter detected
Sep 14 17:39:50 stinkerbelle kernel: [ 3692.447726] usb 4-1: pl2303 converter now attached to ttyUSB0

A blue LED blinks constantly inside the receiver when it is connected: on for one second, off for one second.
