Frequently asked questions

While exact specs may vary, iGPS systems typically operate at 40 Hz, meaning they can update position data 40 times per second—suitable for real-time applications like robotic guidance and dynamic part tracking.

iGPS is infinitely scalable in theory. You can expand the measurement volume by adding more transmitters, with no degradation in accuracy as long as proper calibration and coverage are maintained.

Each sensor collects timing data from laser sweeps, identifies the source transmitter, and sends this information to a central processor. The processor then computes the sensor’s 3D position using geometric algorithms.

The system is designed with redundant coverage—multiple transmitters can see each sensor from different angles. If one line of sight is blocked, others can still provide data, ensuring continuous tracking in complex environments.

Synchronization ensures that all transmitters operate in a coordinated manner, preventing signal overlap and enabling accurate time-stamping of laser sweeps. This is critical for precise triangulation and real-time tracking.

iGPS uses multiple synchronized laser transmitters that sweep modulated beams across the workspace. Sensors detect these beams and calculate their position based on timing and angular data. The use of multiple transmitters allows for redundancy and error correction, maintaining sub-millimeter accuracy over tens of meters.

iGPS is powered by a network of rotating laser transmitters and wireless sensors that use time-of-arrival and angle-of-arrival data to triangulate precise 3D positions. It’s a distributed, scalable system designed for large-volume metrology.

Yes, by adding more transmitters

Surveyor is built using Dot Net technology, so the Surveyor has to run on a Windows PC, but we do have a solution to create a very thin and simple data provider software to relay the data from Windows PC to a Linux PC.

iGPS’s max tracking speed depends on the transmitter layout, especially how far away from detectors to transmitters. From a single transmitter point of view, it is measuring angular velocity. iGPS has been tested by tracking cars moving at 90Km/h outdoors.

Several factors to consider the dynamic tracking capability:

• Typical Update Rate: iGPS systems often operate at 40 Hz or higher, meaning they can update position data 40 times per second.
• Latency: Usually in the range of 10–100 milliseconds, allowing for near real-time tracking.
• Motion Tracking: Capable of tracking objects moving at several meters per second with high accuracy, depending on the number of sensors and environmental conditions.

These capabilities make iGPS suitable for:

• Real-time robotic guidance
• Dynamic tool tracking
• Monitoring large structures in motion (e.g., aircraft components during assembly)

Based on the general principles of laser-based metrology systems like iGPS (Indoor Global Positioning System), here are some typical environmental considerations:

Typical Environmental Requirements for iGPS:

Temperature Stability:

Sudden temperature changes can affect measurement accuracy due to thermal expansion of structures and air refractive index changes.
A stable temperature environment is ideal, often within ±1–2°C.

Humidity Control:

High humidity can affect laser transmission and cause condensation on optics.
Recommended relative humidity is typically between 30%–70%, non-condensing.

Air Quality:

Dust, smoke, or airborne particles can scatter laser beams and reduce accuracy.
Clean environments or filtered air systems are preferred.

Vibration and Movement:

Vibrations from nearby machinery or foot traffic can interfere with measurements.
Systems are best used in low-vibration environments or with vibration isolation.

Lighting Conditions:

While iGPS uses active laser emitters and sensors, excessive ambient light (especially direct sunlight) can interfere with optical components.
Controlled indoor lighting is ideal.

Line of Sight:

The system requires clear line-of-sight between transmitters and sensors.
Obstructions or reflective surfaces can cause signal loss or measurement errors.

The amount of equipment is heavily affected by the size of the measurement volume and the occlusion of the environment, typically, the bigger the volume the more equipment will be required to cover it. Also the more occlusions at the site will also require more equipment especially the transmitters.

iGPS is manufactured in Cambridge Ontario. We also have R&D activities in Québec. It is a full Canadian product.

Yes, both indoors and outdoors although it is not waterproof

No. This is a line-of-sight system although one or two transmitters can be blocked when more that three transmitters are used in a system.

Yes. iGPS is designed for real-time tracking, making it suitable for dynamic applications like robotic guidance, tool movement monitoring, and live assembly verification.

iGPS performs best in stable indoor environments with controlled temperature, humidity, and minimal vibration. Clear line-of-sight between transmitters and sensors is essential for accurate tracking.

iGPS is widely used in aerospace, automotive, heavy machinery, and robotics, where large-scale precision and dynamic tracking are essential.

The iProbe is a handheld device that works within the iGPS system. It allows operators to take precise point measurements anywhere in the workspace, making it ideal for inspection, alignment, and verification tasks.

Unlike fixed CMMs or laser trackers, iGPS is scalable and distributed. It can cover entire factory floors, track moving objects in real time, and integrate directly into manufacturing processes without interrupting workflow.

iGPS uses a network of laser transmitters and mobile sensors. The transmitters emit modulated laser sweeps, and the sensors detect these signals to calculate their position using triangulation. This allows for continuous, accurate tracking across large areas.

iGPS (Indoor Global Positioning System) is a large-scale, laser-based metrology system that enables real-time, high-precision 3D tracking of objects, tools, and assemblies within an indoor environment.

Yes, multiple measuring probes or tracking sensors can be used at one time.

Yes, we offert battery pack solution

No, the rain will interfere with the laser beams, so the accuracy will be compromised and the iGPS equipment are not IP rated currently.

Yes, as long as the number of transmitters are enough to cover the total area, working cells can be defined and dedicates to different applications/tasks that would be all monitored by iGPS
