OmniSTAR L-Band is a subscription-based differential signal.
An SLX receiver using OmniSTAR can operate throughout 95%
of the world, wherever OmniSTAR coverage is available. An
SLX receiver with an active OmniSTAR subscription will
automatically lock onto the differential satellites necessary to
improve accuracy to within one meter, and will automatically
choose the correct frequency, depending on what part of the
world you are operating in. Different parts of the world may
have different OmniSTAR subscriptions.
• e-Dif: ~ < 6 feet (2 meter) accuracy
e-Dif is a differential correction, designed by Hemisphere GPS
for use with the SLX receiver. Hemisphere GPS developed e-Dif
for our customers who are not able to receive other types of
differential signals due to location or budget.
e-Dif can be used anywhere on the globe where a GPS lock can
be achieved. Once you receive e-Dif differential, you can
operate for 1 hour or longer using the initial corrector. During
the first hour, position accuracy is typically within 2 meters,
relative to the original location. See
http://www.hemispheregps.com for more information on e-Dif.
