<viric> in linux, AP, is it possible to do some kind of filtering, like "clients connected with SNR < 70dB, don't connect"?
<whitequark> I don't think that there is a builtin feature for that
<whitequark> it should be reasonably trivial to add though
<whitequark> also, 70 dB SNR is... a lot :D
arossdotme has joined #qi-hardware
<viric> I meant -70dB :)
<viric> and I thought I was asking at #openwrt ;)
<larsc> that's not so much
bikepunk-Work has quit [Remote host closed the connection]
<viric> kristianpaul: I read about GPS:
<viric> "GPS signals receivers - as could be used in mobile phones - are required
<viric> to shut-down when the device realizes itself to be moving faster than 1,200
<viric> mph and is at an altitude higher than 60,000 feet."
<viric> (to avoid they being used in intercontinental missiles)
<whitequark> yep
<whitequark> sparkfun sells gps modules without altitude lock, though I believe they still have speed lock
<viric> wasn't kristianpaul making a gps for intercontinental missiles?
pcercuei has joined #qi-hardware
<larsc> the only thing missing are the IVMs ;)
<larsc> ICMs
<viric> :)

<wpwrak> viric: so, Dr. Strangelove Jr., how is your project today ? ;-)
<viric> hehe
wolfspraul has joined #qi-hardware
wej has joined #qi-hardware
<kristianpaul> viric: misil? no
<kristianpaul> but yes thats posible
<kristianpaul> ah wait
* kristianpaul finishing reading backlog
<larsc> do you need to compensate for velocity when receiving a gps signal?
<kristianpaul> well you always neeed to compensate dopplet and others variables
<kristianpaul> so i think yo do
<kristianpaul> s/dopplet/doppler/g
ffio has joined #qi-hardware
MistahDarcy has joined #qi-hardware
<kristianpaul> but satellites moves faster than your actully could?..
<larsc> yea, i was wondering if you local velocity matters at some point
<kristianpaul> for rtk aplications it matters for sure, but then we have alternative navigation
<kristianpaul> i dont think you can let just gps or glonass do the fix, for that accuracy in real time
Freemor has left #qi-hardware [#qi-hardware]
<kristianpaul> at least you are just mapping and can afford post-processing
<kristianpaul> viric: second, looking wikipedia article about the subject
ffio has quit [Quit: WeeChat 0.4.1]
<kristianpaul> viric: yes all becuse then http://en.wikipedia.org/wiki/CoCom
<kristianpaul> yes i was (hold) working on an embedded gps receiver inside a fpga (m1)
<wpwrak> step 1: design GPS system without speed and altitude restrictions. step 2: sell it to north korea. a major difficulty may be to find something north korea could give you in return, though.
<viric> I also had in mind north corea
<viric> :)
<kristianpaul> also i think Artyom (from gnss-sdr.ru )get something to work but had troubles with locking
<kristianpaul> wpwrak: no need http://www.gnss-sdr.org/
<kristianpaul> but of course sdr driven by python seems not that efficient..
<kristianpaul> portable and etc :)
<larsc> a rocket has enough energy
wej_ has joined #qi-hardware
<kristianpaul> and the key is the correlator, piski guys did what seems a great job releasing and what seems to a fresh libraries (in c) for some glue gnss-gps processing
<wpwrak> wow. catalunya has the tld .cat ? didn't know that. and of course, someone snatched lol.cat :-(
<kristianpaul> but the fpga model is not in their plans las time i asked
<kristianpaul> :-( <- :-(

<lkcl_> hi folks looking to get the kicad source for the nanonote,
<lkcl_> isn't working
<lkcl_> although.... i thiiiink.... that name gave me a lead
<lkcl_> and i've already got it :)
<wpwrak> avt2 is not quite the ben. it's basically an improved ben design. has usb and i think twice the RAM.
<wpwrak> usb host i mena
<pcercuei> twice the RAM?
<pcercuei> 64MB? :p
<lkcl_> ooo 64mb woow
<lkcl_> i'm looking for a DDR1 or SDRAM part
<lkcl_> it's for a GPL EOMA68 project, a router/NAS using the RTL8189
<lkcl_> that P3V56S.... that's what i need, right?
