Designed in cooperation with Grand Idea Studio (, the Parallax Global Positioning System (GPS) Receiver Module is a fully integrated, low-cost unit with on-board patch antenna. Using the industry-standard SiRF StarIII chipset, the GPS Receiver Module is a complete GPS solution in a very small footprint (1.93” x 1.42”).

The GPS Receiver Module provides standard, raw NMEA0183 (National Marine Electronics Association) strings or specific user-requested data via the serial command interface, tracking of up to 20 satellites, and WAAS/EGNOS (Wide Area Augmentation System/European Geostationary Navigation Overlay Service) functionality for more accurate positioning results.

The Module provides current date, time, latitude, longitude, altitude, speed, and travel direction/heading, among other data, and can be used in a wide variety of hobbyist and commercial applications, including navigation, tracking systems, mapping, fleet management, auto-pilot, and robotics.
