Fully integrated ARPA radar

K-Bridge ARPA radar display unit
K-Bridge ARPA radar operator station with 23" high resolution TFT display. The alphanumeric keyboard is concealed within the console when not in use.

K-Bridge ARPA radar is our latest series of type approved ARPA radars. It is provided as a stand alone ARPA radar or as a fully integrated part of the K-Bridge integrated navigation system. It provides superior target tracking and has advanced navigation integration with multi-sensor input. K-Bridge can include electronic chart functions and automatic navigation and track steering when part of a K-Bridge integrated bridge system. The colour display presents a square radar picture, which gives an increased active radar display area for better traffic surveillance. A dedicated operator panel gives ease of operation
