Ublox Antaris 4

I have Ublox AEK-4P and an AEK-4T development kits. These consist of a GPS module (LEA-4P or LEA-4T respectively) in a small case with a USB interface, a serial port adapter and a patch antenna on a really long coax cable.

I will put more information here as I collect it...

I am looking at using the AEK-4P as a GPS data source for a Kenwood TM-D710A.

Here is the serial port datasheet. File:Ublox serial port adapter.pdf

The AEK-4T is based on the LEA-4T module. The interesting thing about the 4T is that it can output raw data that can be processed to achieve centimeter level accuracy at low cost. See more at Low-cost RTK

Reading data on the Mac

Plug it in and then run a copy of the "screen" program.

Device is currently showing up as /dev/tty.usbmodem1411 so this works:

% screen -U /dev/tty.usbmodem1411

The output looks good! Need a new button battery for the Ublox too, it's been on the shelf a few years.

How about a nice program to read NMEA data and display it on my Mac? QGIS is not currently an option.
