NavCom's StarFire Network is a global satellite-based augmentation system (GSBAS) that provides five centimeter positioning accuracy on a worldwide basis, completely independent of geographical boundaries, allowing users to roam freely while maintaining the most precise positioning information.
 

METHODOLOGY

The StarFire Network is a major advance from earlier ground based augmentation systems because it considers each of the GNSS satellite signal error sources independently. GNSS satellite orbit and clock corrections are calculated from a global tracking network of dual frequency receivers. These corrections are transmitted via geo-stationary satellite links direct to StarFire receivers, resulting in minimal data latency and worldwide operation with a minimum 10° look angle to the geostationary satellites. All StarFire receivers use a multi frequency GNSS receiver that measures the ionospheric delay for each satellite. Tropospheric zenith delays are calculated from a multi-state time and position model aided by redundant satellite observables.

APPLICATIONS

StarFire receivers are available as fully integrated units or modular systems. Applications that can benefit from StarFire performance, accuracy and availability include:

• Land Survey
• Offshore Positioning
• PrecisionAgriculture
• Aerial Photogrammetry and LIDAR

• GIS and Asset Mapping
• Machine Control
• Unmanned Vehicles
• Government & Military
