Overview
About the PointSky
PointSky is CHC Navigation L-Band satellite-based GNSS correction service for high-accuracy real-time positioning without a local base station or cellular network connection. Designed for remote, offshore, agricultural, surveying, and network-limited environments, PointSky uses PPP-based correction technology to model and correct key GNSS error sources, including satellite orbit, clock, hardware bias, and atmospheric delays. Corrections are broadcast via geostationary satellites to help compatible CHCNAV receivers maintain reliable centimeter-level positioning in supported service regions.
