Epoch-by-Epoch™ Positioning and Navigation

The fundamental characteristics of Geodetics' technology for static, kinematic and dynamic positioning and navigation are implemented in real-time or post-processing of previously collected data.

Positioning Characteristics

  • Integer-cycle phase ambiguities are resolved independently at each epoch for a network of GPS receivers
  • Relative site positions estimated to centimeter-precision with only a single epoch of GPS data from 5 or more satellites
  • Special treatment of atmospheric effects allows extended-range several times the maximum distance achieved by RTK systems

Navigation Characteristics

  • Absolute real-time (autonomous) determination of attitude & heading of moving platform with 2-3 receivers/antennas
  • Integer-cycle phase ambiguities are resolved independently at each epoch
  • Precision of about 0.01 degrees in attitude and heading (2 meter baseline)
  • Precise relative positioning of moving platforms (no base station required)

Single Epoch Positioning: Horizontal Components, ~15 km Baseline


Single Epoch Positioning: Horizontal Components, ~40 km Baseline
