I wonder if this is a HAE vs. MSL issue? What is the elevation delta for your location in FL? It's about 18 meters for me in Seattle.
Mark, do you know? /tvb
Hello, TimeNutters-- While we are on a thread about Trimble T-bolts, perhaps someone might expand on why my T-bolt does not ever come up with altitude readings that are even close. After a long fix, the Lat-Lon coordinates are pretty close, but the altitude is always given as around 2 meters. We are pretty low here in Flori-DUH, but not THAT low. My ground elevation here is 28M ABMSL and my GPS antenna is another 8M above that on top of my fireplace chimney. I have roughly 50 ft of RG-59 cable on the antenna, but altering the cable length value does not seem to have any effect. I get these same very low altitude readings with TBOLTMON and Lady Heather v3 beta. Since I know my altitude well withing one meter, should I enter that manually? What is the procedure for doing that? Suggestions...?? Thanks!! Mike Baker
