in linux, AP, is it possible to do some kind of filtering, like "clients connected with SNR < 70dB, don't connect"?
14:14
<
whitequark >
I don't think that there is a builtin feature for that
14:14
<
whitequark >
it should be reasonably trivial to add though
14:14
<

also, 70 dB SNR is... a lot :D

kristianpaul: I read about GPS:
15:24
<
viric >
"GPS signals receivers - as could be used in mobile phones - are required
15:24
<
viric >
to shut-down when the device realizes itself to be moving faster than 1,200
15:24
<
viric >
mph and is at an altitude higher than 60,000 feet."
15:25
<
viric >
(to avoid they being used in intercontinental missiles)
15:27
<
whitequark >
sparkfun sells gps modules without altitude lock, though I believe they still have speed lock
15:27
<
viric >
wasn't kristianpaul making a gps for intercontinental missiles?

do you need to compensate for velocity when receiving a gps signal?
18:11
<
kristianpaul >
well you always neeed to compensate dopplet and others variables
18:12
<
kristianpaul >
so i think yo do

s/dopplet/doppler/g

but satellites moves faster than your actully could?..
18:15
<
larsc >
yea, i was wondering if you local velocity matters at some point
18:19
<
kristianpaul >
for rtk aplications it matters for sure, but then we have alternative navigation
18:19
<
kristianpaul >
i dont think you can let just gps or glonass do the fix, for that accuracy in real time

at least you are just mapping and can afford post-processing

yes i was (hold) working on an embedded gps receiver inside a fpga (m1)
18:31
<
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.
18:32
<
viric >
I also had in mind north corea
18:32
<
kristianpaul >
also i think Artyom (from gnss-sdr.ru )get something to work but had troubles with locking
18:33

but of course sdr driven by python seems not that efficient..
18:33

portable and etc :)
