iGPS - Factory-wide measuring, positioning and tracking system
iGPS is a modular large scale metrology solution that transforms large production facilities into accurate metrology-enabled areas. Within the facility, an unlimited number of handheld measurement probes or tracking sensors can operate concurrently.
Unique iGPS capabilities in terms of scalability, robustness and concurrent use provide quick return on investment as well as a solution that grows along with expanding manufacturing operations.
Supports factory-wide deployment (iGPS)
Easily deployable for measuring the dynamic positioning of handheld probes, articulated arms, laser radars and other measurement equipment
Uniform accuracy throughout the entire workspace
Point localization accuracy down to 200 µm
Concurrent use of an unlimited number of handheld probes and tracking sensors
Large scale positioning and tracking suited for aerospace, shipbuilding, train, etc.
Part joining and assembly
Dynamic tracking of parts, tools, robot positions, AGVs and ship models in water tanks
Handheld large volume inspection in automotive (engineering lab, racing workshop), aerospace and other industries like casting and turbine blade production
Automatic annotation of handheld NDT measurements with positional information
The operation of an iGPS system is comparable to a global positioning system (GPS) in a car, but it is designed for industrial applications on a facility-wide scale. GPS satellites are replaced by infrared iGPS laser transmitters that activate a measurement field as large as an entire room or facility. iGPS features accuracies that are roughly a hundred thousand times higher than consumer GPS systems.
Ideal for measuring, positioning and tracking applications
Specific points on tools and parts can be measured using iGPS receivers in the form of touch probes. Similarly, the wings and fuselage of an aircraft can be equipped with tracking sensors that dynamically follow their individual positioning during aircraft assembly, for example.
Open solution that grows along with your metrology needs
The measuring volume can be scaled by just adding more transmitters. There are no limitations as to the number of transmitters, always providing 360 degrees part coverage.
Uniform accuracy for industrial large scale application
The typical accuracy of an iGPS system is 200μm. Where traditional metrology equipment accuracy decreases with distance and as a result of leapfrogging-related measurement errors, iGPS accuracy is uniform across the entire measurement volume, regardless of the size of the metrology enabled area.
Continuous health monitoring
Continuous health monitoring including on-line compensation in case of transmitter displacement and drift, guarantees optimum system performance without user intervention.
Unlike traditional laser-based metrology tools, iGPS offers 360° part coverage without line-of-sight issues thanks to transmitter redundancy.
Multi-user for concurrent applications
iGPS has the unique ability to serve multiple users simultaneously without performance loss. Once a work cell is iGPS-enabled, additional users and new applications can be added with minimum additional investment. Next to supporting a range of handheld metrology devices, iGPS positions tools or tracks multiple objects simultaneously, such as automated guided vehicles (AGVs) in a manufacturing environment.
Easy to deploy and straightforward to use
Installing iGPS on the shop floor is easy and straightforward: just set up the transmitters on their portable tripods and calibrate the system by walking around in the measurement volume while holding a calibrated scale bar. As such, shop floor measurement eliminates the need to transport large heavy parts to/from the measurement room.
Nikon Metrology iGPS helps LASR Lab research advanced trajectory following for space applications.
Engineers at the Texas A&M University’s LASR Laboratory use iGPS to provide the HOMER robot with sub-millimeter trajectory following. Space applications cover experiments involving a 1:10 scale model of the Hubble Space Telescope.
