    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. As an alternative to delivery of corrections via satellites - NavCom offers a StarFire Over IP software option that allows users to access StarFire corrections over the Internet, giving them access to the same reliable five centimeter global positioning accuracy without the need for a base station. Users are able to access StarFire corrections in those situations when satellite delivery might be unavailable, such as deep urban canyons or very high latitude locations.

  • Subscription plans
    StarFire™ five centimeter positioning is available on a subscription basis to end users of our SF Series GNSS receivers. There are two types of StarFire™ subscription licenses: Land Only (excludes all oceans/offshore), All Areas (global coverage). Licenses can be purchased for the following time increments: Monthly (30 days), Quarterly (90 days), Semi-annually (180 days), Annually (365 days)
  • Distinguishable features
    As a Global Satellite-Based Augmentation System (GSBAS), the StarFire™ Network holds a significant advantage over differential GNSS (dGNSS) systems. Since no base station is required, the StarFire™ user is free to roam, with no limitations on range. StarFire™ provides one set of corrections for the entire world, as opposed to dGNSS systems' baseline-dependent regional corrections, which are geographically limited.
  • Typical applications
    Land Survey, Offshore Positioning, Precision Agriculture, Aerial Photogrammetry and LIDAR, GIS and Asset Mapping, Machine Control
