Thank you for your interest.
iSpace is based on iGPS - or infrared GPS - technology. It is an optical technology that allows you to track moving objects in a space of virtually unlimited size.The technology is called iGPS, because it 'imitates' the standard GPS functionality: however, in stead of satellites, one uses laser transmitters that are installed in a room (or outdoors) and that send out infrared light. With iGPS one can determine the position and orientation of an object with a static accuracy down to 0.2 millimeters. The technology is suited for static, quasi-static and dynamic measurements.
With iSpace one creates a true 'metrology enabled workspace', in which all kinds of objects (also e.g. another measuring device, a robot,...) can be tracked.
How it works:
A number of laser transmitters are installed in a room (or outdoors). They send out infrared light. Sensors are attached to the moving object(s). These sensors capture the light signals from the different transmitters. Based on these signals and based on the (known) position of the transmitters, the position of the sensors is calculated (analog angular data). Amplifiers convert the analog data into digital data. Receivers process these data and send them to the software, who converts the angular data into positions and orientations.
The number of needed transmitters depends on the required accuracy and on the size and shape of the required measurement volume. iSpace is a modular system: transmitters and sensors can be easily added (e.g. to enlarge the work space) or removed.
What if a person or object temporarily interrupts the 'line of sight' between a transmitter and a sensor? No problem! As long as 2 transmitters 'see' the sensor, there is no interuption in the tracking data. This results in a excellent system robustness.
Key benefits:
* a virtually unlimited work space
* parallel tracking of a large number of objects
* robustness
* the system takes little or no floorspace
* static accuracy down to 0.2 mm (0.008 inch)
* can be used indoors and outdoors
A few example applications:
Tracking of ship models in a basin
iSpace transmitters are installed on tripods around the basin.Sensors are attached to the ship models.
The exact movements of the models are tracked.

Automated assembly of aerospace components
Sensors are installed on the wings and on the fuselage. iSpace transmitters are attached to the walls.
The position and orientation of the different parts is monitored. These data are used to 'guide' the different parts to their correct position.
