NAVCOM STARFIRE
Five Centimeter Global, Real-Time Accuracy - Without a Base Station
The first of its kind, this global satellite-based augmentation system (GSBAS) 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.
REAL-TIME GLOBAL ACCURACY
Less than 5 cm one-sigma per horizontal axis (10 cm vertical) using NavCom algorithms and receivers
No local base station / radio comm. link required
Global availability
All orders for StarFire service require a completed StarFire Signal License Instrument sent to info@westlat.com.
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
