Correction Services

CenterPoint® RTX, Trimble RTX's premier correction service, provides accuracy better than 4 cm (1.5") via satellite or cellular. No other satellite delivered correction service performs better.


  • Availability: Worldwide
  • High Accuracy: Provides  < 4 cm (1.5") horizontal accuracy*
  • Quick initialization: CenterPoint RTX converges to full accuracy in 1-5 minutes in select regions, and less than 30 minutes worldwide,** see coverage map for details
  • Multi-constellation support: GPS, GLONASS and QZSS enabled
  • More uptime: Continue working through correction signal interruptions for up to 200 seconds
  • No base station required: No longer worry about losing radio signal connectivity since a base station is not required for Trimble RTX-based correction services
  • Cost Effective: No additional data or cellular plans required
  • Fast Restart (Agriculture) and Quick Start (Survey): Decrease the standard** initialization time to less than 5 minutes at the beginning of each day by starting your tractor in the same place you shut it off the night before
  • Benefit for farming:  Achieve greater productivity in the field when planting, spraying or spreading.  High accuracy, Trimble CenterPoint RTX, can reduce overlap by 90% - 95%.  This equates to up to a 5% savings on input costs.***

* All horizontal accuracy specifications are based on in-field performance 95% of the time.


** Receiver convergence time varies based on GNSS constellation health, level of multipath, and proximity to obstructions such as large trees and buildings.


*** As compared to planting using a guidance system or guidance system with SBAS corrections with a 40 ft planter.  Results may vary based on equipment, field size and other conditions.

Type of Subcsription

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.

 

OmniSTAR G2 represents the most recent advancement in OmniSTAR subscription service offerings. It is a worldwide dual frequency high-accuracy solution which uses Orbit and Clock correction data. OmniSTAR G2 includes GLONASS satellites and GLONASS correction data in the solution. The addition of GLONASS to the solution significantly increases the number of satellites available which is useful when faced with conditions that limit satellite visibility, such as terrain, vegetation or buildings. OmniSTAR G2service provides short-term accuracy of 1-2 inches and long term repeatability of better than 10 centimerers, 95%CEP. It is especially suited for operations in areas where trees or buildings may block the view of the sky and in areas affected by scintillation during times of high sunspot activity.

 
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 10 centimeters, 95%CEP. 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.
 
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.
