thinwing Posted August 9, 2011 Report Posted August 9, 2011 Just saw on av web about the possibilty of GPS signal disruption occuring after last thursdays rather energetic solar flare.Any of you operating amateur radio equipment late fri night and sat saw some amazing propagation...especially on 20 meter band.Anyway it looks like we are coming out of a 10/11 year solar minimum into a maximum.Gps ,especially waas was not widely used 10 years ago during last solar maximum,so who knows???Anybody with wass gps units see any disruption last sat ???I flew Sat morning to get cheap gas...no problems in northern calif...sinc kp couch Quote
HopePilot Posted August 9, 2011 Report Posted August 9, 2011 Yes, on Sunday both WingX and my KLN94 both freaked out on me. Quote
Jerry 5TJ Posted August 9, 2011 Report Posted August 9, 2011 That's funny, my Loran has been acting odd, too. Must be the solar flare. de N6JH Quote
Skybrd Posted August 9, 2011 Report Posted August 9, 2011 I flew last Saturday and my Garmin GPS worked with no difficulity. I read about the solar flares but haven't heard of any disruptions. EMP (electro magnetic pulse) can clobber solid state electronics and it's possible that the GPS satellites have extra shielding for that. I've had my GPS loose satellites for unknow reasons on VFR trips but shortly it cleared up. I think its always a good idea to keep track where your at and have maps accessible. -- 73, wb6dbw Quote
M016576 Posted August 10, 2011 Report Posted August 10, 2011 WAAS shouldn't be affected, as the basis behind WAAS architecture is that the GPS signal is augmented by ground stations near the terminal environment, thus providing a more controlled, more accurate and more reliable signal to the host aircraft... I think.... can anyone tighten me up on this? Quote
thinwing Posted August 10, 2011 Author Report Posted August 10, 2011 Loran,omega,adf...LOL..lots of funny replys and had no idea of the # of Hams onboard.....anydody doing any aernautical mobile ops just for grins???M016576...I will try..the ground stations recieved the some satalite signals as our airbourne equipment...but they insert a correction based on their known precise position.That correction travels thru phone lines to the sat ground station in Virginia and broadcast backup to the original satalite.The Sat in orbit broadcasts that correction factor and our airborne recievers apply it.The solar flare besides containing speed of light photons and xrays and other good stuff puts out a lot of slower moving protons as a residue of atomic fusion.When this cloud of protons hits the atmospere (F layer ionospere)it creates an ionization layer much more reflective than regular sunlight.Result is good propagation of earth generated radio waves(they get reflected and bounce up and down for long distances)radio blackouts from too much ionization..of in case of radio signal from space to ground ,gets reflected back into space .This is highly frequency dependent and gps signals are ultra high frequency...so can pass thru easier...but this last flare was very powerful...m9.3 almost a x(ten) event so scientists didnt really know for sure...kp c ouch Quote
thinwing Posted August 10, 2011 Author Report Posted August 10, 2011 yikes my typing was really stinko in that last post!!!!No wonder I never get a replys using PSK 31!!!..LOL kpc Quote

fantom Posted August 10, 2011 Report Posted August 10, 2011 Has anyone tried this stuff for sunspots? Quote

Vref Posted August 11, 2011 Report Posted August 11, 2011 We have AUGUR in Europe to see if we can fly to Mars http://augur.ecacnav.com/augur/app/home These Nanus remind a lot of Mork & Mindy...nanu nanu...well ain't that Mars...? Quote
