GPS 101

PrecisionPro uses GPS technology to help measure area and distance but most importantly as a speedometer. PrecisionPro obtains industry standard accuracy with 4.5m (16ft), which is the same as modern day smartphones.

31 operational GPS Satellites provide 95% accuracy for speed, timing and location.

GPS satellites broadcast their signals in space with a certain accuracy, but what you receive depends on additional factors, including satellite geometry, signal blockage, atmospheric conditions, and receiver design features/quality.

Accuracy

This shows how accuracy can be effected by objects

Many things can degrade GPS positioning accuracy. Common causes include:

  • Satellite signal blockage due to buildings, bridges, trees, etc.
  • Indoor or underground use
  • Signals reflected off buildings or walls ("multipath")

Far less common causes may include:

  • Radio interference or jamming
  • Major solar storms
  • Satellite maintenance/maneuvers creating temporary gaps in coverage
  • Improperly designed devices that do not comply with GPS Interface Specifications

PrecisionPro has been designed developed to help you apply granular and seed products more accurately than ever before. Using the built in speedometer to walk the correct speed is vital for optimum distribution, also keeping the spreader at a consistent angle too.

PrecisionPro also allows users to help measure area and distance using modern day GPS capabilities. Although not 100% accurate, the Measure feature is designed to help users understand approximately the size of area being treated. *If you require a more accurate form of measurement we would recommend using a dedicated company providing digital gps and mapping, although this can be costly.
