What's new in version 6.43/5.83 (September 2025)

We recommend that you carefully review this information for any possible impacts to workflows and take appropriate action to avoid disruptions.

CAUTION – All data files in the receiver are deleted when you install new firmware. Before you start, ensure that you first download any data files from your receiver to your computer.

For information about software compatibility, see Supported software.

Main changes and improvements

Cybersecurity enhancements. For new R780 / R780-2 receivers activated after 1 August 2025 or R780 / R780-2 receivers upgraded to v6.43/5.83 and later, the following enhancements have been made:

  • Temporary failed password lockout. On the receiver Login page, you have five attempts within ten minutes to log in. If the login fails, the account is locked for 10 minutes. See Security / Config.

  • Bluetooth pairing. Bluetooth legacy pairing has been disabled and PIN codes are no longer supported. See Bluetooth / Configuration.

  • HTTP Secure. By default, HTTPS is now enabled and HTTP is disabled. See Network Configuration / HTTP.

  • Install new firmware via web interface. By default, firmware installation via the web interface is disabled. See Firmware / Install New Firmware.

  • Secure File Transfer Protocol. SFTP is now the default transfer mode for the FTP Push feature. See Data Logging / FTP Push.

  • TCP/IP ports. See I/O Configuration / Port Configuration / TCP/IP port settings.

    • New output only options have been added to the TCP/IP port configuration settings.

    • TCP/IP ports 5017, 5018, 28001, and 28002 have been removed.

  • Wi-Fi access point encryption. See Wi-Fi / Access Point.

    • WPA2-AES is now the only available encryption type for the WiFi access point.

    • For receivers that have the Wi-Fi feature. The default password (encryption key) is now the serial number of the receiver, not abcdeabcde.

  • Zeroconf. By default, the Enable Zeroconf service discovery is disabled. If you depend on this to locate a new receiver connected to a network, select this check box to turn it on. See Network Configuration / Zeroconf/UPnP.

Issues with corrupt firmware or frequent crashes. You can now access the boot monitor of the receiver to reinstall or upgrade firmware in the rare event that the firmware is corrupt or there is repetitive restart issue. See Network Configuration / HTTP.

Update to TIP tilt compensation performance specification

Firmware version 6.43 includes enhancements to Trimble TIP™ tilt compensation technology for supported receivers. As a result of these enhancements, the horizontal positioning performance specification for TIP compensated surveying has been improved.

New TIP compensated surveying horizontal positioning performance specification:

  • RTK/RTX precision + 3 mm + 0.15 mm/° tilt (up to 40°) RMS

Requirements to achieve the specified performance by receiver model:

Receiver model

Minimum firmware version

Additional requirements

Trimble R780

6.43

  • Pole Bias Adjustment must be performed

  • No use of Quick Release adapter

Trimble R780-2

6.43

  • Pole Bias Adjustment must be performed

  • No use of Quick Release adapter

NOTE – Correct surveying techniques should be followed to reduce multipath error and maintain a good line of sight to the sky for satellite tracking. At greater than 40° of tilt, horizontal position precision at the rod tip may decrease more than specified.

New Trimble RTX Fast Coverage for the Republic of Korea (South Korea)

Trimble has announced a new regional area network providing CenterPoint® RTX Fast services for the Republic of Korea. In this area, regional atmospheric models to mitigate ionospheric and tropospheric biases are available from a dense network of Trimble RTX® reference stations via the internet on the RTXKR mount point. L-band users can continue to use the RTX Pacific-Asia (RTXPA) beam with global ionospheric models.
