iXblue’s Atlans A7 INS.. (Photo: iXblue) Oceanographic & Geophysical Instruments (OGI) has selected iXblue’s Atlans INS to provide robust and uninterrupted data georeferencing to its newly unveiled mobile-mapping lidar solution dedicated to road assessment surveys. A fully integrated mobile mapping solution, this new vehicle-based system integrates advanced systems to provide highly detailed georeferenced survey data to transportation departments throughout the United States. “Highly accurate and reliable georeferencing of the collected data being crucial for road assessment operations, we were seeking a compact and robust navigation solution for our mobile scanner project,” said Darren Moss, program manager at OGI. “We tested other inertial navigation systems (INS) during mobile surveys in New York City and Boston with poor results, as those INS units relied mainly on GPS signals. Maintaining good GPS signals in the urban canyons of large cities proved to be impossible. This deeply impacted the georeferencing of the acquired lidar data, leading to highly inefficient operations. This is the reason we turned to iXblue’s Atlans A7 INS.” Based on fiber-optic gyroscope (FOG) technology, the Atlans A7 north-seeking INS offers highly accurate and robust data georeferencing. Resistant to GPS outages, it enables continuous acquisition operations within environments lacking continuous GPS signals. The Atlans A7 is a valuable system for high-accuracy data acquisition without interruption. “Working with iXblue in other markets, we were familiar with the high-quality instrumentation they are known for. We were confident their FOG-based INS systems would perform even during GPS outages,” Darren said. “By choosing the Atlans A7, we are assured to get robust and uninterrupted georeferenced data in urban environments, tunnels, forests, and mountainous areas, which is crucial for our customer’s operations. With this INS, iXblue brings high-end FOG performance to the mobile-mapping industry at a very affordable price.” “The Atlans A7 integrates very well within our new mobile lidar solution and, combined with Teledyne Optech Polaris high-resolution lidar scanner and QPS Qinsy display and acquisition software, it brings high-accuracy and efficiency to the core of our Mobile lidar solution,” Darren said.
