Argo Navis firmware update v3.0.1 on Linux

Since the end of last year, there is a new firmware for the Argo Navis Digital Telescope Computer available. I'm using an old laptop running on Linux with a serial port to connect the Argo Navis. As I couldn't find a lot of information on how to do the upgrade using Linux on the Internet, I wrote down the procedure I followed to do the upgrade.

The upgrade to version 3.0.1 offers a lot of interesting new features:

• Support for multiple telescope setups.
• The moon is added to the list of objects, including lunar phase and time of phases.
• Horizon filter added.
• Updated object catalogs.
• Updated ServoCAT protocol. I don't own a ServoCAT, so for me, this is not really useful.
• ...

Steps to upgrade the Argo Navis firmware to version 3.0.1.

• Download the new firmware from http://www.wilcard-innovations.com.au/firmware.html
• Note down the settings of your Argo Navis in the SETUP tab.
• Put the serial cable in the 'Serial 1' port.
• Start up your Argo Navis while pressing the EXIT button. You should see 'BOOT LOADER 1.0.x' on the screen of the Argo Navis.
• Start the firmware upgrade by typing :

sgzload -s /dev/ttyS0 -f navis_app300.sgz

• The Argo Navis upgrade should start. Both on the screen of the Argo Navis and on the computer screen you can follow the progress.
• After finishing the upgrade, re-enter the settings and add your location in SETUP LOCATION.

Adding comets to your Argo Navis

• Download the latest orbital elements from http://www.minorplanetcenter.net/iau/Ephermides/Soft06.html
• Check the visibility of the comets on http://cometchasing.skyhound.com/ or http://www.aerith.net/comet/weekly/current.html
• Rework the list from the Minor Planet Center to only contain the visible comets (don't use more than 10 comets).
• Start up the Argo Navis and select the 'SETUP LOAD CAT' mode. 
• Upload the comet database to the Argo Navis using the following commands:

catload -s /dev/ttyS0 -c comet -p
catload -s /dev/ttyS0 -c comet -f Comets201502.txt -w 

• To make your life easier, I will put my monthly list of comets in a file on Google Drive.
