CAST EMT3500-3 EGI Diagnostic Tool
According to research conducted by the US military about Embedded GPS Inertial (EGI) maintenance actions, most of the EGIs returned to the manufacturer are actually functioning well. These fully functional EGIs are squawked off aircrafts, which often leads to high rates of RTOK or Re-Test OK. There is a lack of troubleshooting equipment, unfortunately, and the current process is to return the EGI to the depot for evaluation. This is where the CAST EMT3500-3 EGI diagnostic tool comes in. This revolutionary embedded GPS and INS test equipment is specifically designed to help identify errors and failures, ensuring that that EGIs returned to the depot indeed needed repair.
Advantages of the CAST EMT3500-3
CAST Navigation’s GPS/GNSS 3500-3 is user-friendly and easy to operate, making the field equipment ideal for maintenance personnel. It also has a graphical interface that minimizes keystrokes, as well as CDNU-like inputs and outputs that reduce the learning curve. The EGI troubleshooting tool loads and verifies GPS Embedded Module (GEM) and Operational Flight Program (OFP) via 1533, and draws out receiver data through RS-422. Its operating system is Windows or Lynx and is a rack mounted system. The EMT3500-3 also comes with appropriate cabling, a laser printer, and an inertial rate table. With dimensions of 55″ x 24″ x 32″, the tool is lightweight and portable, allowing operators to respond fast to diagnostic requirements. Other key features include OFP Load and Verify, Data Reporting, Almanac Functions, Reprogram GEM, and BIT Read and Initiation.
