Operating several base stations on one radio frequency

In an RTK survey you can reduce the effects of radio interference from other base stations on the same frequency by operating your base station with a different transmission delay.

When you use multiple base stations, you set the transmission delay for each base when you start the base survey. Each base must broadcast with a different transmission delay and station index number. The delays allow the rover to receive corrections from all of the base stations at once on one frequency. The station index numbers let you select which base station to use at the rover.

 

  • You can set the base radio transmission delay only when using Trimble GNSS receivers or the Spectra Geospatial SP100 GNSS receiver.

  • When you carry out surveys using different base stations in one job, make sure that the coordinates of the base stations are in the same coordinate system and are in terms of each other.
