 Fugro AtomiChron® is a global, real-time, precise clock synchronisation and authentication service based on GNSS, for applications that require resilient, accurate and reliable time and frequency. This innovative technology eliminates time drift caused by clocks counting time at slightly different rates and gives users access to extreme frequency stability as well as extreme accurate time references, with levels that surpass high-calibre industrial standard caesium clocks and approaching hydrogen maser performance.

-With AtomiChron, you have the option to use (prefer) the individual GPS or Galileo clock bias from **FugroTimeOffset** over the Fugro composite bias. Please refer to the [ESP32 firmware settings](./software_overview.md#configure-operation) for more details.
+With AtomiChron, the firmware will use the Fugro composite bias reported in **FugroTimeOffset** to discipline the TCXO frequency.

 ### TCP Server (IPS1)
 
-When **TCP Server (IPS1)** is enabled, the ESP32 serial console is diverted from the CH340 (USB) interface to the mosaic-T COM3 UART interface.
-The serial data is then daisy chained from COM3 to the IPS1 TCP server.

-When **TCP Server (IPS1)** is enabled, the configuration menu and debug messages can be accessed over TCP / Telnet on the chosen port. The CH340 (USB) interface is then no longer active.

The configuration menu and debug messages can then be accessed over TCP / Telnet on the chosen port. The CH340 (USB) interface is then no longer active.
 
 TCP / Telnet is supported over both Ethernet and the Ethernet-over-USB connection. Only one TCP2Way connection is supported.
