Hi Folks
Is anyone implementing any form of lightning protection for their
GPS-attached equipment?
If my antenna gets struck or we have a nearby hit (nearest strike to
ground since we moved here was about 470m away, IIRC), I would like to
limit the damage to the GPS module.
My thought was to stick an optoisolator or similar between the serial
and PPS pins and the level converter (MAX232 equivalent) and power the
GPS module itself with one of those little Meanwell high-isolation DC/DC
converters. This is very similar to what I am planning to do with the
outside components of my 1-Wire weather system.
I'd be interested to know what everyone else is doing in this respect
(if anything).
Cheers
M
