Cables and Connectors

A multitude of cables and connectors are needed for GNSS installations, whether for permanent or campaign sites. Generally, for campaign sites, the cables used are proprietary cables that come from the GNSS equipment manufacturer. For permanent sites, however, some cables are customized based on length.

Cables

  • Antenna (GNSS antenna to GNSS receiver) - coaxial cable, typically RG58 from the manufacturer; LMR-200 or greater for permanent installations (see the Times Microwave Systems Coax Selection Guide )

  • Download/data transfer/communications (GNSS receiver to a computer or communications device) - most commonly serial cable, typically RS232; also Ethernet cable for newer receiver models

  • AC Power (GNSS receiver to an AC power source) -proprietary from the GNSS equipment manufacturer

  • DC power (GNSS receiver to a DC power source) - proprietary from the GNSS equipment manufacturer

  • Radio cables (power, communications)
