OmniSTAR is developed and operated by Fugro's global coverage of a
set of high-precision GPS augmentation systems. Through the GPS
satellite to provide enhanced data OmniSTAR is the world market
leader, the system distributed around the world through 70 ground
GPS reference stations to determine the system error, by the
difference in the United States, Europe and Australia, three
control center points on the reference station data analysis and
processing, and confirmed by the analysis of differential
correction data through simultaneous satellite broadcast to users,
to achieve high-precision real-time positioning. OmniSTAR provides
measurement, positioning, environmental and land and offshore,
including satellite services in the application of a new land-based
OmniSTAR services to meet the precision positioning systems.
OmniSTAR provides unprecedented real-time DGPS positioning service.
It can improve the accuracy of GPS receiver by about 100 times.
OmniSTAR system than some other competing systems on the market can
provide greater geographical coverage. At present, OmniSTAR signal
within the coverage of the highest achieving single 10 cm (CEP) in
real-time positioning accuracy.
OmniSTAR differential GPS provides three levels of service: VBS,
HP, and XP.
OmniSTAR VBS is a sub-meter-class service. A typical 24-hour sampling of the
VBS display 2 (95%) confidence level of the horizontal position
error is less than 1m, while the 3 (99%) of the position error is
close to 1m. The new OmniSTAR HP service 2 (95%) of the confidence level of the
horizontal position error is less than 10cm, 3 (99%) of the
horizontal position error is less than 15cm. In the agricultural
machinery guidance and many of the measurement tasks, has its own
unique applications. It is operational real-time, without a local
base station or remote link. Precision in the use of forward
positioning, OmniSTAR HP is certainly a more ahead. The new OmniSTAR XP service providers, a few inches short-term and
long-term repeatability is better than 20cm (95% CEP) accuracy. It
is particularly suitable for agriculture, automation control
systems. And its slightly lower accuracy than the HP, which is
available worldwide, in the measurement, and regional differential
systems (such as WAAS) compared with the precision improved. |
