Basics

  • Up to 20 times per second update rate [1]
  • Resolution drops to a few centimeters once base station is 10km from moving node [2].
  • A Method of Satellite Navigation/Survey that utilizes one or more constellations, and a Base Station
  • This allows for 1cm Level Accuracy
  • Refresh Rate Typically Can Be ~1hz, but 20hz Models Exist (According to SparkFun, further looking around can be done if need be)
  • Useful mainly for Surveying and Precise Remotely Operated / Autonomous Vehicles
  • Low cost cm accuracy in GPS using GLNS module with android - [3]

How Are Boundaries Recorded

  • There is a legal description like [Sec 32, T8N, R1E, E 1/2 of NW 1/4 Ex Com at NW Cor of Sd E 1/2 of NW 1/2, Th E Alg N Ln of Sec 140 ft, S Parl with N&S 1/4 Ln of Sec 311 Ft. W Parl With N Sec Ln 140 ft, N 311 Ft to Beg)] [4]
