Complete GPS/INS Integration Testing
All army and government aircraft require efficient CNS or communications, navigation, and surveillance equipment to effectively and safely operate in both the military and civil airspace. At CAST, we bring you the CAST-3000 embedded GPS inertial navigation system EGI, which supports complete GPS/INS integration testing. With this embedded GPS/INS system in place, the GPS receiver and the inertial sensor are tightly coupled. Similar to other systems, the CAST-3000 produces GPS RF signals, but with simulated inertial measurement unit (IMU) sensor data. This makes dynamic, controlled testing in the laboratory possible for the government and the military. To develop this product, we have worked closely over the past decade with highly reputed names in the industry, such as Northrop Grumman and Honeywell. We have incorporated ammunition and high performing fighter aircraft dynamics to the proprietary laboratory test interfaces to the aerospace and defense technology companies’ inertial navigation products.
How the CAST-3000 Works
The CAST GPS/GNSS satellite 3000 provides real-scenario inputs for both GPS/INS of EGI systems, assuring the GPS/INS navigation solutions do not diverge. The blended solution is exactly what it would be in the real-life scenario. In addition, because it optimally combines GPS and INS features, it provides a tightly integrated solution for enhanced velocity, position, attitude, and pointing performance, as well as improved GPS signal acquisition and anti-jam capabilities. The optimal combination of GPS and INS provides position and angle updates at a quicker rate than just GPS as well. This is especially suitable for high dynamic aircraft and missiles, as INS fills the void between GPS positions. It continues to calculate the angle and position when the receiver loses the GPS signal.
