GPS/INS Measurement Unit Suits Aerial Surveying

Inertial Aerosystems has introduced Systron Donner's SDN500, a MEMS-based GPS/INS tactical inertial measurement unit suitable for tactical aerospace, munitions and platform stabilisation applications. It is also suitable for demanding commercial applications such as top-level laser range finding, animation camera control, robotics and aerial surveying. The performance of SDN500 is based on the SDI's proven quartz MEMS inertial sensor technology. The SDN500 is based on the company's proven tactical grade SDI500 IMU, but now it incorporates a GPS receiver into a tightly coupled powerful guidance and navigation system.

It also combines the latest generation of quartz gyros and accelerometers, high-speed signal processing with a single-board 50 channel course/acquisition. The solid-state quartz sensors and sealed construction provide more than 25,000 hours MTBF and a 20-year operating and storage life. Continuous built in test (BIT), configurable communications protocols, electromagnetic interference (EMI) protection and flexible input power requirements, combined with expert applications engineering support, make the SDN500 easy to use in a wide range of higher-order integrated system applications. Operating temperature is -40 to +71C. The SDN500 measures 73.6 x 73.6mm and weighs 589g, making it suitable for use where space and weight are at a premium.
