(4) Coarse/Acquisition - Miniature Integrated GPS/INS Tactical System (C-MIGITS). The C-MIGITSTM
III Global Positioning System (GPS) and Inertial Navigation System (INS) provides essential three dimensional po-
sition, velocity, precise time, attitude, heading, angular rate, and acceleration. An Inertial Measurement Unit (IMU)
III operates from +28 Vdc provided by an EGI Power Supply. The CMWS on the RC-12 platform can operate in
the pseudo INS mode without the GPS/INS components by installing a jumper cable that changes the aircraft ID
for the ECU. The aircraft ID jumper cable is installed between the wiring harness PP902 and ECU J2 when not
using the C-MIGITS III. This change in aircraft ID indicates which software will be used by the ECU during startup.
Integral to the C-MIGITS are the RS-232 to RS-422 converter and EGI Power Supply. The RS-232 to RS-422 Data
Converter provides bi-directional data transfer between the C-MIGITSTM III and the ECU. EGI Power Supply, this
Power Supply unit regulates and ilters the +28 Vdc aircraft power and is used to supply power to the C-MIGITSTM
III module and the Data Converter.
