jack Posted December 22, 2006 Report Posted December 22, 2006 Can anyone say if G.P.S. is affected by dense fog.?.If so,looks like chart and compass need to be an essential requisite on board ,and the knowledge of thier use. { a dying art, I suspect these days.].. jack Quote
duncan Posted December 22, 2006 Report Posted December 22, 2006 (edited) Can anyone say if G.P.S. is affected by dense fog.?. no, nor rain, snow, nighttime, or the time of the month there is some debate around sunspots though.............. what's esential has never really changed - compass, chart and radar..............

toerag Posted January 5, 2007 Report Posted January 5, 2007 Yep, GPS is fine in all weathers, I've used mine in dense fog, snow and torrential rain. Rain and snow will affect the radar, but you can adjust that to get rid of it. However it'll probably get rid of any reflections from small GRP craft in the process. Quote
Fugazi Posted January 5, 2007 Report Posted January 5, 2007 Another top tip when caught out in thick fog is to remember that while monitoring your position on the GPS screen you don't motor into something else! Keep a really good lookout. Gordon H Quote
Shropfisher Posted January 29, 2007 Report Posted January 29, 2007 The GPS Signal comes from American military satalites ( we will have our own soon ) They used to scramble the signal on a regulare basis, apparently to confuse terrorists, but they no longer do this, I guess they found it screwed them up more than any one else. Not a difficult task. Quote
