Why Choose an i73+ Base Station?
No RTK Network Subscription Required
Operate your own local RTK base and transmit corrections directly to your rover via UHF radio. This makes it ideal for contractors and surveyors working in locations where cellular coverage or RTK network access may be limited.
Built-In UHF Radio
The i73+ features an integrated 410–470 MHz Tx/Rx UHF modem, removing the need for a separate external radio modem for standard base operation.
Long-Range RTK Corrections
The internal UHF radio provides an operating range of up to 3Km.
Survey-Grade Centimetre Accuracy
Deliver the accuracy required for professional surveying, construction set-out, earthworks, drainage, and general positioning applications.
Full-Constellation GNSS
With 1,408 GNSS channels, the i73+ tracks multiple satellite constellations including GPS, GLONASS, Galileo, BeiDou, QZSS and SBAS, providing strong satellite availability and positioning performance.
