Description

OmniSTAR is a world leader in providing high accuracy positioning data via satellite, and is at the forefront in the design and development of Differential GNSS (DGNSS) positioning technology.

Using over 100 reference stations, 6 high power satellites and 2 global network control centers, OmniSTAR delivers real-time and highly reliable positioning services for land and air applicaions worldwide, 24hrs a day 365 days a year.

В зависимост от нуждите и изискванията на потребителя се предлагат следните услуги:

• OmniSTAR VBS - global sub-meter: it 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.

• OmniSTAR XP - 15 cm worldwide: it 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 HP - 10 cm high performance: it is the most accurate solution available in the OmniSTAR portfolio of correction solutions. It is a L1/L2 solution requiring a duel 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 - GPS+GLONASS: this service 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 G2 service 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..

One- and three-month, as well as 1-,  2-, 3- and 5-year terms of subscription to any of these services are available.
