AeroNav GNSS
A Highly Compact System
AeroNav GNSS is a highly compact system including all the basic features needed for navigation guidance and measurement of X,Y,Z projection centers and can support also EXIF information for the Camera.
AeroNav GNSS is an entrance level device for mission navigation and camera control based on c/a coded L1 GNSS receivers that support refresh rates of 10 Hz. The use of GPS, Glonass, BeiDou and Galileo makes this Device an extreme robust positioning and navigation system. This enables precise navigation for accurate aerial imaging.
A bi-directional RS232 communication with AeroTopoL FMS supports camera trigger and camera event management:
Short Facts
Release of an aerial camera using electronic trigger switch (potential free)
Determining the event signal of the camera on an open collector
Event-based positioning with a 1/100-sec accuracy
