Using i73 with tilt

Surveying Cadastral boundaries

Cadastral boundary pegs are easy to survey in new greenfield subdivisions, but brownfield redevelopment projects in older established environs present many surveying "obstacles". Corner boundary peg, right against brick gate pillar and under a tree. CHCNAV i73 mounted on pole, stake directly onto peg and tilted slightly away from pillar and from tree. PDOP, HDOP & VDOP all < 1; Excellent position RMS (EN 13mm, Z 21mm)

Measuring drain asset for GIS (including drain depth)

Modern road water drains are now purposely designed to minimise access by children - which presents a challenge for depth measurement. No problem with CHCNAV i73; simply tilt, lower, measure; DONE! Efficient, accurate, easy.

Recording high-rise building corner

High-rise developments are rapidly increasing. The height and density of such buildings means reduced "visibility" to the GNSS sky - hence possibly reduced measurement accuracy. Maybe for other GNSS systems, but not for the CHCNAV i73! With RTK-IMU tilt; plus full GNSS constellation support (824 signal channels); advanced RTK engine; Adaptive anti-interference & multipath mitigation = Fast, Accurate, Reliable

Promptly validate concrete slab dimensions

No need to waste time concentrating on the bubble! Promptly move the pole to every corner and press "Enter". Validate the whole slab pour dimensions within 1-2 minutes. mm to cm accuracy thanks to CHCNAV advanced RTK algorithm.

Use CORS RTK or for even higher accuracy, set up your own RTK Base station.
