For growers interested in the ability to receive RTK correction from either a radio base station and a cell modem connection to CORS or TopNET, Topcon offers the new AGI-3 receiver.

Topcon Precision Agriculture (TPA) has released a new Real Time Kinematic (RTK) module for the Topcon AGI-3 receiver that includes the capability of receiving data from a radio base station or cell modem connected to GSM networks. The new AGA3928 module replaces the current AGA3677 module.

This new RTK module includes both an internal, spread-spectrum 915 MHz modem for receiving data from a radio base station and a US GSM cell modem for receiving data from cellular data networks such as CORS or TopNET.

CORS networks provide a tremendous cost saving alternative for operators needing RTK correction and the number of available networks is increasing. Since these capabilities are now built into the AGI-3 RTK system, users do not have to purchase additional hardware or modules in order to use CORS networks or GSM.

GSM functionality can be activated by purchasing a data plan and SIM smart card from a GSM service provider.

Existing AGA3677 RTK modules cannot be upgraded to include GSM support. For current users choosing to upgrade by replacing with the new AGA3928 module, firmware installed on the GX-45 console must be version 2.02.18 and version 3.3A5 on the AGI-3 receiver.
