X91+ GNSS
Easy-to-use, efficient and intuitive work flow, designed for advanced network RTK survey, compact and rugged, the X91+ GNSS is the perfect choice for demanding survey applications.
By combining decades of positioning and surveying know-how, the X91+ GNSS is one of the most powerful GNSS RTK solution, with no compromise with quality but at a price point that every surveyors can afford.
The X91+ GNSS RTCM compliance with major GPS brands allow trouble free integration into an existing pool of survey instrument.
