Chapter 4: Differential Correction Types
Differential Corrections Overview
The differential correction type used by S-Lite is selected from the two GPS
applications loaded into the receiver. You can change the correction type from the
CORRECTION TYPE item in the Service menu (see “Service Menu” on page 15). Select
SBAS, e-Dif, or other field-installed correction option(s).
• For North American distribution, SBAS (WAAS) is the factory installed
option. WAAS is free and is available throughout most of North America.
• For European distribution, SBAS (EGNOS) is the factory installed option.
EGNOS, like WAAS, is also free and is available throughout most of Europe.
• For all other locations that do not have access to SBAS corrections like
WAAS or EGNOS, e-Dif is the factory installed option. Use of e-Dif requires
no additional hardware.
Note: e-Dif, as factory installed, is pre-activated with a one-time primary subscription
for use anywhere in the world. The use of e-Dif on Outback Guidance equipment as a
GPS differential correction is intended only for relative guidance applications and is
not recommended for data recording and subsequent comparative analysis. Relative
positional accuracy will typically drift at a rate of 1-2 meters (3-6.5 feet) per hour;
however, absolute positional accuracy errors may approach ±10 meters (±33 feet).
