Northern Indiana | I think SF1 just doesn't have the weather modeling that SF2/SF3/SF-RTK use (where as radio and modem RTK use local RTK base stations thus not needing weather modeling)
That's why SF1 somedays performs just fine and others now - when cloud cover or lack of cloud cover is consistent in and around a region performance is more consistent with SF1

WAAS will sometimes hold within 12 inches for a few hours, and at times it will move 2-3 feet in less than a minute. There is no way to know when it will do the big jumps.
SF1 was (I'm pretty sure) just SF2 with some artificial noise added in to make it move around more. It behaved in a much more stable way than WAAS.
The ITC receivers can no longer get SF1, so it is running on WAAS, and the bridge module just changes the data messages coming from the receiver to say that the signal is SF1 instead of WAAS. It will perform like a receiver on WAAS because that's what it's using.
RTKx and SF3 will have a little more drift than a RTK base. Does this matter? Depends what you're doing. If you're just running a chisel plow, it doesn't matter. If you're doing strip till, it might be an issue. |
WAAS vs SF1 are they the same accuracy?
