Built for India's Survey Professionals
FOIF instruments combine precision manufacturing with global-standard accuracy — and ANRI backs every unit with local expertise.
Channel GNSS
The FOIF A90 tracks all major constellations simultaneously — GPS, GLONASS, BDS, Galileo, NavIC — for faster, more reliable RTK fixes.
Angle Accuracy
FOIF total stations like the RTS-102 deliver 2-second angular precision, meeting the demands of cadastral, construction, and deformation surveys.
Field-Ready Build
Dust and water-resistant housings ensure FOIF instruments survive India's monsoon conditions, construction sites, and remote terrain.
After-Sales Support
ANRI offers Annual Maintenance Contracts, instrument calibration, repair, and on-site support — so your equipment stays productive year-round.
Solutions by Sector
FOIF instruments are deployed across India's most demanding survey environments.
Roads, Bridges & Railways
Use FOIF A90 DGPS and RTS-102 Total Station together for complete construction survey workflows — from alignment to as-built verification.
Cadastral & Land Records
FOIF A90 RTK with NavIC/GAGAN support makes it ideal for government land demarcation, DILRMP projects, and village boundary surveys.
Mining & Quarrying
FOIF total stations handle the demanding geometry of open-cast mines — highwall profiling, blast-hole layout, and volumetric stockpile surveys.
Deformation Monitoring
The FOIF RS10 Robotic Total Station enables automatic, continuous deformation monitoring for bridges, dams, slopes, and high-rise structures.
