How to set up Coban / TK103 on Navtrix

Coban trackers from the GPS103 family — such as the TK103B, TK303 and TK403 — and other TK103-protocol devices work on Navtrix, including the logon and heartbeat that keep the connection open.

Step by step

  1. Create your Navtrix account — 7 days free, no credit card.

  2. In the dashboard, open Devices and add the tracker with its identifier (IMEI or device ID) and the TK103 protocol.

  3. Text the tracker the APN, GPRS mode and server commands with the Navtrix IP number (example below; 123456 is the factory default password).

  4. Start the vehicle (or move the tracker) and wait for the first position on the live map. Your free trial starts counting at that moment.

Server address

Server IP recommended
34.26.86.4
Alternative: server name (DNS)
ip.navtrix.app
Port
5000 (TCP or UDP)

Most trackers only accept the IP number — use it. Use the server name (DNS) only if your model's manual asks for a domain.

SMS commands — by IP (recommended)

apn123456 <apn>gprs123456adminip123456 34.26.86.4 5000

Alternative — with the server name (DNS)

adminip123456 ip.navtrix.app 5000

Commands vary between models and firmware versions: check your tracker's manual. Replace <apn> with your SIM carrier's APN; some firmware asks for a password before the command.

Use the IP number in the adminip command — every Coban firmware accepts it. Many units also take the server name (DNS) in the same command. Power-cycle the tracker after configuring.
