The Trimble Placer line of GPS receivers has a proven track record of exceptional reliability and longevity. Continuing the Trimble tradition of high performance and robust GPS receivers for mission critical applications are two state-of-the-art Trimble models: Placer Gold APU and Placer Gold Dead Reckoning Unit Plus.

Trimble Placer Gold models are equipped with two independent, configurable RS232 serial ports (both of which may be used with an RS232 to USB 2.0 adapter), user selectable interface protocols and user selectable port speeds (bps). Each port delivers location information to any in-vehicle device that accepts a GPS data input in a TAIP, NMEA or PPP interface format. This data allows dispatchers or managers to schedule automatic vehicle location reports based on time and/or distance traveled.


  • 12-channel quick start receiver
  • Compatible with most CAD, GPS tracking and workforce management systems
  • User configurable reporting based on time, distance & time or polling
  • Two configurable output ports
  • User-selectable interface protocols, including TAIP, NMEA and PPP
  • Direct connection to mobile computers and select RF data radio
  • Easy to read power on and satellite lock indicator lights
  • Rugged and compact
  • DRU Plus model includes dead reckoning sensor for when intermittent loss of satellite signals is experienced
  • Integrates with the GPS tracking software you already have
  • Configures to your company's needs
  • Flexible reporting options allow you to select the best method for your company
  • DRU Plus calculates data when no GPS signal is available, giving you more complete information about your vehicle's location
  • Wireless laptop or direct RF radio connection capabilities means you're always connected to your mobile workers
