OMNISTAR
OmniSTAR is a wide-area differential GPS service, using satellite broadcast techniques. OmniSTAR offers GPS correction
services that improve the accuracy of a GPS receiver alone. The OmniSTAR services include dual frequency (L1/L2) carrier
phase solutions. The accuracy depends on satellite geometry, local conditions, receiver capability, and other variables.
Typically, the L1/L2 solutions from OmniSTAR XP provide horizontal accuracies of +/- 3.1 to 3.9 inches (8.0 to 10.0 cm) and
OmniSTAR HP provide horizontal accuracies of +/- 2.0 to 3.9 inches (5.0 to 10.0
cm). By using L1/L2 atmospheric corrections and carrier phase techniques, these services can achieve higher levels of
accuracy than WAAS or EGNOS.
The OmniSTAR signals are transmitted on different beams around the world. The GPS receiver must be configured to listen
to the correct beam for its location.

OmniSTAR can usually provide a subscription over the phone with a credit card and you can see the subscription status
change. OmniSTAR offers a quick, efficient subscription initialization and renewal service available 24 hours a day.
GeoSteer systems support two levels of OmniSTAR service:
OmniSTAR XP
—XP is defined as better than 7.9 inches (20 cm).
OmniSTAR HP
—HP is defined as better than 3.9 inches (10 cm)
The selection of XP or HP in your receiver is determined by the subscription sent to a receiver when it is activated by
OmniSTAR. Be sure to tell OmniSTAR which subscription to activate.
