2-12-1-CenterPoint-RTX

Trimble CenterPoint RTX

Trimble® CenterPoint™ RTX™ delivers GNSS (GPS, GLONASS, QZSS, BeiDou) enabled, repeatable 1.5-inch (3.8 cm) corrections to your receiver anywhere in the world. Available via satellite or cellular delivery, CenterPoint RTX Standard converges to the full accuracy in 30 minutes or less. Positions may also be used much sooner at a lower accuracy level—the user decides. CenterPoint RTX corrections can be delivered directly to the built-in receiver of your Trimble BX982™ receiver, BX935-INS® ,Geo 7X hand held, CFX-750™ display, or AG-372 GNSS receiver.

Trimble® CenterPoint™ RTX™ Standard delivered via satellite is the most accurate satellite- delivered correction service available. It doesn’t require an RTK base station or cellular service and is available throughout North America, South America, most of Europe, Russia and the Commonwealth of Independent States (CIS), Africa, Asia and Australasia.

2-12-2-Omnistar-HP

OmniSTAR HP – 10cm High Performance

OmniSTAR HP service is the most accurate solution available in the OmniSTAR portfolio of correction solutions. It is a L1/L2 solution requiring a dual frequency receiver. OmniSTAR HP corrections are modeled on a worldwide network of reference sites using carrier phase measurement to maximize accuracy. The expected 2-sigma (95%) accuracy of OmniSTAR HP is 10cm. It is particularly useful for Agricultural Machine guidance and many surveying tasks. It operates in real time and without the need for local Base Stations or telemetry links. OmniSTAR HP is a true advance in the use of GPS for on-the-go precise positioning.

Delivery: Via Satellite

2-12-3-Omnistar-XP

OmniSTAR XP – 15cm Worldwide Service

OmniSTAR XP is a worldwide dual frequency high accuracy solution. It is a L1/L2 solution requiring a dual frequency receiver. Orbit and Clock correction data is used together with atmospheric corrections derived from the dual frequency data. By utilizing carrier phase measurement, very high accuracy can be achieved. OmniSTAR XP service provides short term accuracy of 1-2 inches and long term repeatability of better than 15 centimeters, 95%. It is especially suited for Agricultural automatic steering systems. While it is slightly less accurate than OmniSTAR HP, it is available worldwide and its accuracy is a significant improvement over regional Differential Systems such as WAAS.

Delivery: Via Satellite

2-12-4-Omnistar-VBS

OmniSTAR VBS – Global Reliable Sub-Meter Accuracy

OmniSTAR VBS is the foundational “sub-meter” level of service. It is an L1 only, code phase pseudo-range solution. Pseudo-range correction data from OmniSTAR’s regional reference sites is broadcast via satellite link to the user receiver. These data are used, together with atmospheric modeling and knowledge of the receiver’s location, to generate an internal RTCM SC104 correction specific to that location. This correction is then applied to the real time solution. A typical 24-hour sample of OmniSTAR VBS will show a 2-sigma (95%) of significantly less than 1 meter horizontal position error and the 3-sigma (99%) horizontal error will be close to 1 meter.

Delivery: Via Satellite

Available worldwide

Provides better than 1m horizontal accuracy

Converges to full accuracy in less than 5 minutes

GPS, GLONASS, BeiDou, and QZSS enabled

No base station required

Ideal for general utility infrastructure, environmental management, road works and

park management.
