The Garmin GPS 18x is an OEM, high-sensitivity GPS sensor for use in automotive, fleet vehicle, and electronics applications that require a small, highly accurate GPS receiver.

Use in Small Spaces

This high-sensitivity, 12-parallel-channel, WAAS-enabled GPS receiver is available in CMOS-level serial or USB 2.0 full-speed versions and comes with an integrated magnetic base. The puck-like receiver is 2.4" (6.1 cm) in diameter and weighs just a few ounces, making it an ideal solution for applications where space is at a premium.

Choose Your Connection Type

The GPS 18x is offered in 3 different cable configurations. All 3 versions of the GPS 18x come complete with non-volatile memory for storage of configuration information, a real-time clock and raw measurement output data for sophisticated customer applications.

  • GPS 18x PC (This Page) has DB-9 pin serial connector with a 12 V cigarette lighter adapter; can output data in NMEA 0183 format (industry standard) or proprietary Garmin format.
  • GPS 18x USB has A-style USB connector, compatible with USB 2.0 and 1.1 full-speed hosts; can output data in Garmin proprietary format only.
  • GPS 18x LVC has bare wire for connection to a variety of applications; can output data in NMEA 0183 format (industry standard) or proprietary Garmin format; provides a pulse-per-second logic-level output with a rising edge aligned to within 1 microsecond of UTC time.

The GPS 18x OEM is a high-sensitivity GPS sensor that replaces the GPS 18 OEM.
