OmniSTAR: Differential Global Navigation Satellite System (GNSS) Solutions
The entity known as OmniSTAR, now a part of Trimble Inc., is a long-standing and recognized global provider of high-accuracy differential Global Navigation Satellite System (GNSS) correction services. The company's core function is to deliver reliable, accurate GNSS positions to its customers worldwide, significantly enhancing the precision and productivity of positioning-reliant applications. OmniSTAR operates as a Satellite-Based Augmentation System (SBAS) service provider, utilizing a proprietary network and geostationary satellites to broadcast correction signals.
The primary business of OmniSTAR is to overcome the inherent inaccuracies of standard satellite navigation by providing correction data. This data is derived from a worldwide network of ground reference sites that monitor GNSS signals, calculate real-time errors, and then transmit these corrections via geostationary communications satellites to users??? GNSS-capable receivers. This system allows for precise, real-time positioning without the necessity of setting up local base stations or relying on expensive telemetry links, making the service especially valuable for companies operating in remote locations.

OmniSTAR???s services are foundational to many industry sectors requiring high-precision field operations and reliable geospatial data collection. The service provides global coverage across most of the world's inhabited landmasses through its network of geostationary satellites, ensuring instant access to accurate positioning data.
Key Application Areas:
- Agriculture (Precision Farming): OmniSTAR services support the implementation of precision farming techniques, helping growers optimize all aspects of the crop production cycle through highly accurate machine guidance, which in turn helps reduce costs and increase yield.
- Mapping & GIS (Geographic Information Systems): The services offer convenient and reliable positioning solutions for data collection activities anywhere globally. This ensures that plotted survey data is reliable and accurate, aiding in tasks such as boundary surveys, data acquisition, resource mapping, and mapping utilities lines and assets.
- Mining: The high-precision coverage is used to simplify operations, providing mining companies with reliable, precise, and accurate positioning data for their complex activities.
- Railways: OmniSTAR services are deployed to manage fleet operations, significantly improving efficiency, safety, and overall railway operations.
- Aviation: Providing worldwide coverage for aerial applications where instant and reliable positioning is critical.
Products and Services Portfolio
OmniSTAR offers a tiered portfolio of Differential GNSS solutions, each designed to meet varying levels of accuracy and application requirements. These services are accessed via a subscription and require an OmniSTAR-capable receiver, which is available from a number of major GPS manufacturers. The company's offerings include both single-frequency and dual-frequency solutions:
1. OmniSTAR HP (High Performance)
* Accuracy: Up to 10cm (0.1 meter) horizontal accuracy (2-sigma, 95% of the time).
* Technology: This is the most accurate solution in the OmniSTAR portfolio. It is an L1/L2 dual-frequency solution that utilizes carrier phase measurement. The corrections are modeled on a worldwide network of reference sites to maximize precision.
* Primary Use: Agricultural Machine Guidance and various surveying tasks demanding high precision.
2. OmniSTAR XP
* Accuracy: Horizontal accuracies of less than +/- 15 cm (95% of the time).
* Technology: An L1/L2 dual-frequency solution that makes use of precise orbit and clock corrections of the GPS satellites, often leveraging data purchased from entities like NASA JPL.
3. OmniSTAR G2
* Technology: A high-accuracy service similar to XP. It uses orbit and clock corrections calculated from OmniSTAR???s own network of global reference stations, a distinction from the XP service.
4. OmniSTAR VBS (Virtual Base Station)
* Accuracy: Horizontal accuracy of less than +/- 1 meter (95% of the time).
* Technology: This is a single-frequency (L1-only) code phase DGPS solution. It offers a more accessible entry point for DGPS accuracy.
The range of services ensures that customers can select a subscription level that perfectly matches their required accuracy, from sub-meter differential GPS for general mapping to sub-decimeter carrier-phase-based solutions for advanced machine control and surveying.
