4 Typical Doppler installations
Pages 1

Doppler principles can either be used in self-

contained navigation systems, or as stand-alone

velocity sensors. An early (1970s) version of a

control display panel used on the MR1 Nimrod

aircraft is illustrated in Figure 15.9. The stand-

alone velocity sensor is in the form of a radar

transmitter-receiver as illustrated in Figure 15.10,

item 1. This sensor has a resolution of less than

0.1 knots and can be interfaced with other avionic

systems and displays using data bus techniques.
