GM SMART is a professional Bluetooth GNSS receiver built for using with agricultural guidance software. Designed for spraying, seeding and field operations, it provides stable 10–15 cm pass-to-pass accuracy using free satellite signals — no subscriptions, no RTK corrections, no hidden costs.
Key Features
GM SMART combines proven hardware, an intelligent coordinate-smoothing filter, and universal NMEA output — everything you need for reliable parallel guidance on any crop operation.
Proprietary coordinate-smoothing filter delivers repeatable relative accuracy for spraying, seeding, and cultivation — without paid corrections.
Simultaneously tracks GPS, GLONASS, Galileo, and BeiDou on L1 — maximum sky coverage for robust signal reception in any field.
Streams standard NMEA sentences over Bluetooth. Works with any Android guidance app — no proprietary drivers, no lock-in.
Supports RTK corrections for centimeter-level accuracy when needed. Compatible with base stations within a recommended 5 km baseline distance.
Why Accuracy Matters
The market is flooded with cheap receivers using technologies that are not suitable for stable work on moving agricultural machinery. GM SMART is engineered differently: its built-in smoothing algorithm was developed specifically for parallel guidance, providing consistent row-to-row accuracy that cheaper alternatives cannot match.
