Pre-GO PPP with SMA Connector
High precision GPS
The Pre-GO PPP (Precision Geolocation) uses U-Blox Precise Point Positioning algorithm to give high accuracy geolocation without external computational burden. The antenna is not onboard: attach an external antenna. Use with a Raspberry Pi running rtklib, the u-blox NEO 7P GPS/GLONASS receiver provides the raw data output required for centimeter-level accuracy.

Pre-GO PPP: High precision GPS with SMA antenna connector
Featuring the u-blox Neo-7P GPS/GLONASS module, the Pre-GO PPP SMA board offers a PPP (Precise Point Positioning) solution for your location-aware project, delivering centimeter accuracy. RTKLIB-compatible output makes this product ideal for surveying, cartography and geodetic applications. Precision geolocation in a 30x24mm form factor.
This model includes an SMA connector for an external antenna (not included).
Pre-GO modules can connect to any host board with an available UART connection. Logic levels are at 3.3V, and the board is powered by the 5V supply; however, by removing and replacing a jumper resistor, the board can be powered by a 3.3V source.
A Geppetto designer has the choice of including a header on a custom-design that connects via 5-pin cable to one of these PreGO boards as shown by these examples. Alternatively, the GPS module can be placed directly on a board.
