Chapter 4: Differential Correction Types
Using e-Dif
The patented e-Dif correction method uses only the standard GPS satellites and does
not require an external correction signal of any type.
e-Dif works by analyzing the error trends from the GPS satellites and projects new
correction values into the future. This technique is stable and accurate within short
time frames making it perfect for progressive pass-to-pass guidance. As long as each
pass is within a few minutes of the last pass, the accuracy performance is excellent.
Selecting e-Dif
To configure S-Lite for use with e-Dif: select e-Dif as the
correction type on the Service menu.
To then use S-Lite with e-Dif: follow the general directions in
this manual, but review the following section first regarding
power on initialization and DGPS lock.
Power On Initialization and DGPS Lock
After powerup, S-Lite must track GPS satellites for up to 10 minutes before generating
differential corrections. The vehicle may be moving or stationary during this time.
• While tracking, the yellow GPS LED
illuminates and the display shows the
number of satellites being tracked
(‘Tracking 8 Sats’ shown at right).
• When S-Lite is finished tracking, the
green DGPS LED illuminates and the
display indicates ready (‘Ready - 9
Sats’ shown at right).
