In 2003 CAST developed a product that has the capability to test and evaluate an EGI unit either on the flight line or in the back shop. We called this product line the EGI Maintenance Tester (EMT). This product line allows the end-user to validate proper operation of the GPS receiver, perform inertial testing on the IMU sensors, up/download almanac data, run BIT testing, validate EGI interfaces and load OFP software. This capability provides our military customers an alternative to sending the units back to the manufacturer for an RTOK status thus saving both time and money.
