I think having an opensource satnav is a great idea and has a large potential to showcase and use OpenStreetMap data. I suspect there are millions of SatNavs out there by now (mostly WinCE based), for which the maps slowly get more and more outdated. As map updates are quite expensive, I would guess a fair few people would be interested in trying up to date OpenStreetMap maps on these device, if there is a good free satnav solution.

However, I was wondering if it might be more fruitful to contribute to one of the existing open source satnav projects already out there, rather than starting a new one? Navit ( for example seems quite promising. It is GPL licensed, fairly active and there seem to have been some ideas on porting it to Android based systems floating around. Navipowm ( might be another possibility as well as gosmore. Just thoughts though.

Navit as an Android option?

Good ideas. Navit looks promising, but at the moment, it only seems available as a tar ball. Without modifying (hacking) the G1, it is not possible to do root stuff with tar balls.

As I say, opensatnav is just an idea, and it's objectives are freedom and portability to the G1 (Android) and Openmoko.

Homebrew hardware

I would like the possibility to port this software to homebrew hardware, i.e. I would like to make my own unit from scratch. --Skippern 14:15, 7 February 2009 (UTC)

projects objectives and requirements

So... what is this Satnav going to do exactly when and if it is finished? --MarcusWolschon 08:48, 23 February 2009 (UTC)

See para's 3) and 16). --Chris debian 15:21, 24 February 2009 (UTC)
They only state that it shall do routing but not if it does the route-calculation on the device, via ORS or via another server, if it does the map-rendering on the device, downloads already rendered tiles to the device or only shows tiles from the web. They also do not state what other devices besides that one smartphone-model it is supposed to run on. If you do route-calculation and/or rendering on the device I may be able to help you with working code to adapt. --MarcusWolschon 08:03, 25 February 2009 (UTC)
In my opinion, the software should be capable of working in a complete offline environment as well as online. --Skippern 11:18, 25 February 2009 (UTC)
So, what kind of storage-space and processing-power are we speaking about? --MarcusWolschon 19:19, 25 February 2009 (UTC)
See next topic. --Skippern 19:33, 25 February 2009 (UTC)

System requirements

We need to look at various systems, and what kind of limits they have in storage capacity, processing capacity and memory (RAM), for homebrew systems, I think most of them can be built with higher specs than most embedded systems, and handheld systems that are in retail at the moment. What kind of processing capacity does the most common GPS cellphones have? PDA? What kind of memory does these units have? Internal storage capacity? What kind of memory cards can be used as external storage? How is external storage accessed? --Skippern 19:32, 25 February 2009 (UTC)

AndNav2 OpenSource

As of Jan 2010 AndNav2 is open sourced. Is there any interest in combining these two projects?

I am very much in favour of there being an OpenSource SatNav. OSM is the obvious route data. I think it would have to come with sync software. I guess the idea is you know where you are going, you go on OSM, modify the route from OS opendata/ Bing maps etc, add points of interest and make the map perfect for you. Then you just drive the route you just did. This would push the 'completeness' of the map a long way. I think it would also be good if the satnav device could also take a GPS trace as it goes, so when you get home you can upload your trace for further improvement of the map. I see this as having some advantage in the UK, Europe, USA, but I think it would have MASSIVE impact in developing and badly mapped regions. One thing though, I support the idea of it running on Android above anything else. Why? Because it would be very easy for independent manufacturers to take some hardware, load Android (free) and then a platform for the satNav would be easily integrated. It also allows the open sat nav software to run on the worlds most popular phone OS. This would have bigger impact than a stand alone device. 12:50, 1 March 2011 (UTC)

Still alive?

Is this project still alive? The server and communication channels look pretty dead as mentioned in this forum thread. --Tordanik 22:50, 8 October 2012 (BST)
