    en.wikipedia.org/wiki/StarFire_(navigation_system)

    StarFire is a wide-area differential GPS developed by John Deere's NavCom and precision farming groups. StarFire broadcasts additional "correction information" over satellite L-band frequencies around the world, allowing a StarFire-equipped receiver to produce position measurements accurate to well under one meter, with typical accuracy over a 24-hour period being under 4.5 cm. StarFire is ...

    The accuracy inherent in the SA however, was too poor to make this realistic. The military received multiple requests from the Federal Aviation Administration (FAA) , United States Coast Guard (USCG) and United States Department of Transportation (DOT) to set SA aside to enable civilian use of GNSS, but remained steadfast in its objection on ...

    Few civilian receivers have ever used the P-code, and the accuracy attainable with the public C/A code was much better than originally expected (especially with DGPS), so much so that the antispoof policy has relatively little effect on most civilian users. Turning off antispoof would primarily benefit surveyors and some scientists who need ...

  7. Starfire Optical Range - Wikipedia

    en.wikipedia.org/wiki/Starfire_Optical_Range

    The purpose of Starfire is to conduct research to use adaptive optics to remove the effects of scintillation (atmospheric turbulence). [1] Turbulence interferes with laser beam integrity over distances. Lasers are being used for long-distance high-bandwidth communications and accuracy in air-to-air laser connectivity is important for data ...

    The actual measured accuracy of the system (excluding receiver errors), with SA turned off, based on the findings of the FAA's National Satellite Test Bed, or NSTB. WAAS Measured 0.9 m / 1.3 m The actual measured accuracy of the system (excluding receiver errors), based on the NSTB's findings. Local Area Augmentation System (LAAS) Specification

  9. GNSS enhancement - Wikipedia

    Greater accuracy may be obtained by processing triple-difference results for additional sets of three independent time pairs. This will result in an overdetermined system with multiple solutions. To get estimates for an overdetermined system, least squares can be used.
