Garmin GPS 18x LVC
5+ $69.50

The GPS 18x is a small, highly accurate GPS sensor featuring a 12-parallel-channel, WAAS-enabled GPS receiver and an integrated magnetic base. The receiver is 2.4 inches in diameter and weighs just four ounces (115 grams), and unlike many other receivers in its class, it can operate at extremely high altitudes, making it a favorite of high-altitude balloon experimenters.

The unit defaults to output data in the industry standard NMEA 0183 data format, but may also be user programmed to output data in the GARMIN proprietary format. It also provides a pulse-per-second logic level output whose rising edge is aligned to the UTC second within 1 microsecond.

The 15 foot (5 meter) cable is terminated in bare wires, with a 6-pin connector installed for factory testing. This connector can be removed and replaced with another connector, or it can be used to mate with JST part number BM06B-SRSS-TBT or SM06B-SRSS-TB connectors.
