Product overview

The ZHTAERO Z Rtk is a positioning and heading component for UAV integration. Its physical architecture combines a single module with two antennas, placing its function within the aircraft’s navigation system. The product is identified as a module rather than a complete flight platform or airframe kit. Its centimeter-level positioning capability relates to the RTK figures; the GPS and DGPS figures describe separate levels of positioning accuracy under their respective modes.

GPS positioning accuracy is specified as 1.5m horizontally and 2.5m in elevation. DGPS assisted positioning reduces those figures to 0.4m + 1PPM horizontally and 0.8m + 1PPM in elevation, while RTK specifies 0.8cm + 1PPM horizontally and 1.5cm + 1PPM in elevation. Maximum satellite search capability is GPS: 28+ and RTK: 50+. Acquisition time also depends on the starting condition, with a cold start below 30s and an assisted start below 5s.
