Lassen SQ

The SQ is a module slightly larger than a quarter which has pretty good specs. Low power and pretty good accuracy. The pin-compatible IQ is even better but I got this SQ from eBay awhile back so it's what I am playing with. If this is too much fun to handle I will get an IQ later.

Launch

I obtained a developer board with USB from SparkFun.com and I have plugged the SQ into the board and powered up by connecting a USB cable.

To get it going, I installed Windows 2000 drivers from Silicon Labs and am now running the iQ_Monitor.exe program which SparkFun has on their website. It's running on com port 8. iQ_Monitor is a dandy free program.

The other program iQ_Chat wants to talk on funny serial ports that I don't have -- com1 and com2. :-) I am running W2K in VMware right now.

iQ_Monitor

I am in my house right now and the Trimble antenna is in my window. I doubt it has a good view! The Magnavox (with the antenna on the roof sees these satellites: 01,02,04,13,16,20,23,24,27

Here is a screen shot of the program right now.

Linux

Linux 2.6.12 finds the right driver and I can see it via minicom on /dev/ttyUSB0 but I think it defaults to TSIP mode so I can't find the right baud settings. (I think it's in binary mode)

I want to put a GPS Almanac into the board manually. Have to download one,

I need to get a 12mm battery for the developer board to keep the almanac around when the computer is powered down.
