GPSr Units / WAAS problem with Garmin 62s
« on: November 02, 2010, 03:54:41 AM »
I have discovered what I think is a problem with the (or maybe just my) Garmin 62s, and I'm wondering if anyone else has noticed this.
If my 62 looses the WAAS satelite signal, it will attempt to find another WAAS satelite if available.  If it is unable to locate another WAAS signal, it NEVER attempts to use WAAS satelites again, for the rest of that "power up" sesion. What I mean is, say I enter an area with no WAAS coverage, loose the signal, then after a few minutes return to an area with WAAS coverage.  The 62s will not regain the WAAS signal no matter how long it tries, until I shut it off and back on (at which point it IMMEDIATELY reaquires the signal).

General Discussion / A question about accuracy for the gurus
« on: October 28, 2010, 08:26:46 PM »
I'm using my new garmin 62s gps to do a "rough" survey of my 40 acres....basically, I'm marking (and re-marking/averaging) all four corners of my property.  Then I plan to put in the four to a route, and use the routing lines as a rough property line guide to post some "No Trespassing" signs.  To be on the safe side, I'll post them 10 feet or so in from the route line.
My question is:  would it matter, for utmost accuracy, which "position format" I use?  ie. hddd mm.mmm, vs hddd mm ss.s, vs hddd.ddddd?  Does the gps carry decimal places beyond what it displays?  If not, it would seem to me that the last choice (hddd.ddddd) would hold the most accuracy for the following:
hddd mm ss.s ......this carries minutes to 1/600, or degrees to 60,000th
hddd mm.mmm....this carries minutes to 1/1000, or degrees to 600,000th
hddd.ddddd..........this carries degrees to 1 millionth

or are my figures wrong?  (i'm no math major!!!)

GPSr Units / Can not get waypoints off of Garmin 62s
« on: October 27, 2010, 05:17:47 AM »
Hi all,
I've got a new GPSmap 62s, and I'm having a problem getting waypoints from it.  I'm using mapsource.  It will accept waypoints (send to device) but when I try to "receive from device" it always says there are no waypoints on the unit when there actually are....why?

Oh, and btw, although this 62s is new, I'm no stranger to garmin or mapsource...I've had about a half dozen previous garmin gps, marine units, aviation units, etc.
