Centre county Pennsylvania, USA | We've not experienced any problem this week with EZ steer using Trimble's EZGuide-500 with WAAS corrections. We do have the EZ-500 configured to use WAAS satellites 135 and 138, and all visible GPS satellites, in the position fix. That seems to give best performance (lowest HDOP and lowest "dropped calls").
Trimble's planning software is showing brief periods when GPS satellites are providing poor (very high) HDOP here this month. We don't see those poor HDOP periods on EZ-500 guidance screen's DGPS overlay when that overlay is showing that WAAS (SBAS) satellites are being used in position fixes. WAAS satellite usage in position fixes shows on EZ-500 guidance screen overlays as a star after each of the two WAAS satellite numbers. |
