MMQG INS / GPS Instrument Grade Navigation System-1

Miniature MEMS Quartz GPS/INS Ideal for High-Precision Civil & Military Applications: • • • • • • • • Targets & Drones Position & Orientation System Stabilization UAVs & Other Unmanned Vehicles Range Instrumentation Commercial Aviation Navigation Railroads Helicopter Extremely Small Size Integrated INS/GPS Optimized 28-State Kalman Filtered Navigation Solution RS-232 Digital Interface Low Power Consumption (<5W) Accepts External Magnetometer Data for Heading Reference In-Air Dynamic Alignment Capability1 The MMQ™G offers a unique combination of the Systron Donner Inertial solid-state Inertial Measurement Unit (IMU) and the Jupiter PICO™ commercial Global Positioning System (GPS) receiver. The MMQ™G's MEMS quartz rate sensors and MEMS accelerometers make up an IMU system that is tightly coupled with the Jupiter's 12-channel Coarse/Acquisition (C/A) Code GPS engine to provide a highly accurate navigation solution. The MMQ™G also accepts 3-axis magnetometer data, which it uses as a heading reference in order to improve heading stability. This also allows for alignment during low dynamic motion, as experienced in ocean applications. A “heading hold” feature allows delayed takeoffs after alignment is complete. The MMQ™G combines tremendous performance and versatility with an extremely compact size and low weight at a very low price. Leveraging the C-MIGITS® III user-friendly message based navigation outputs, the MMQ™G provides a powerful solution for Guidance, Navigation & Control. 1 In-Air dynamic alignment without magnetometer reference requires system velocity below 95 kts.
