ТМ4-3 (ТМ4-3/110) tracker

The TM4-3 (TM4-3/110) mobile terminal is designed for mobile objects control systems (MOCS) on railway that provide on-line remote monitoring and control of vehicles. 


  • object positioning based on signals of satellite navigation systems (SNS): Russian Global Navigation System (GLONASS) and US Global Positioning System (GPS)
  • monitoring of object and cargo status via five sensors with high or low output signal level, and three current sensors
  • data reading from fire protection system and KLUB locomotive safety system via CAN interface
  • transfer of object position, sensors status data and telemetry data from locomotive safety system to MOCS control center via GSM cellular network with General Packet Radio Service (GPRS)
  • control of four actuating devices installed on objects under MOCS control center commands
  • internal memory recording of minimum 1000 information frames in case of data transfer channel failure and automatic transfer of frames to the control center when data transfer channel is restored
  • automatic identification of a cellular service provider via SIM-card
