Z15 Posted October 30, 2003 Posted October 30, 2003 Anyone notice poor GPS solutions today. I was out looking for a old USGS mark (prim trav sta from 1907) today, had 11 SV'S locked including WAAS SV35 and the best solution was 37 feet? SPACE WEATHER Mike Survey Tech (Retired) Quote
+porterhill gang Posted October 31, 2003 Posted October 31, 2003 I have an old Eagle Expedition that I bought back in 1996-97....no WAAS functionality. I found a benchmark yesterday and checked the GPS and it was measuring 83 feet off. Quote
CallawayMT Posted November 1, 2003 Posted November 1, 2003 On Wednesday the 29th I was using a Trimble 5800 Receiver to finish tieing some section corners, set 3 aliquot land corners and then do a small 10 acre topo map. This RTK receiver is one of the newest survey grade receivers out on the market right now. It was running great in the morning, but around 1PM I had 8 satellites all fixed on the L2 frequency and a good configuration; I could not get the unit to initialize(which means it can not work out the amiquities to get down to survey grade accuracies). I had a known point in the field and forced initialization which did work, but the unit lost init within seconds. Normally with the circumstances involved I would have init within 10-20 seconds. As I watched the satellites being tracked, they would go up to 8 and down to 3, continuously going up and down. I was in a place where obstructions such as trees and mountains would not have been causing this. I had work to do and so I used a total station to finish out the day. I did leave my GPS running and checked on it later and it was still having proplems. So I did figure that the Solar storm was actually affecting my GPS. Quote
+Barefoot Posted November 4, 2003 Posted November 4, 2003 Thought I was the only one. I was out for a cache Oct 31st and managed to get within 100 yards before my GPS would acquire a signal. Something like 20 minutes. I thought it was a Halloween thing. Thanks for letting me know I'm NOT nuts. Not totally anyway. Quote
Kerry. Posted November 4, 2003 Posted November 4, 2003 It may only get worse. Today the GOES-12 satellite recorded the most intense flare ever measured and simply went past the max measuring capability. The associated solar radiation storm is following. Cheers, Kerry. I never get lost everybody keeps telling me where to go Quote
