Stonex S990+ GNSS Receiver

The S990+ is Stonex's proven, survey-grade workhorse receiver, trusted by professionals who demand the full package of precision, connectivity, and reliability on demanding RTK and static applications. Equipped with 1408 channels tracking all major constellations including GPS, GLONASS, BeiDou, Galileo, and QZSS, it delivers consistently accurate positioning in even the toughest environments. The advanced IMU system enables tilted measurements up to 60° with fast initialization, accelerating fieldwork by up to 40% and eliminating the need to perfectly level the pole on difficult terrain. A dual-frequency UHF radio covering both 410-470 MHz and 902.4-928 MHz makes it the ideal base-rover solution across international deployments, while an integrated 4G modem keeps network RTK corrections flowing wherever cellular is available. The onboard color touch display and Web UI give operators direct, intuitive control of the receiver in the field, and the 1PPS port adds precision timing capability for multi-instrument synchronization workflows. With a 10,200 mAh battery delivering up to 12 hours of operation and an IP67 rating, the S990+ is built to go the distance.
