GNSS Testing

Global Navigation Satellite System (GNSS) refers to all satellite positioning systems in use, such as GPS, GLONASS, Galileo, Beidou and other regional systems.

We can create a realistic GNSS environment in our test chambers to test the performance of a device in any environment you want – for example on the streets of your home country, or here, in the pure arctic nature of Finland.

We provide world’s fastest GPS Air Performance Test for Wearable Devices such as smart watches.

GNSS Testing According to ETSI EN303-413

Functionality is ensured by two tests:

  •  Adjacent Frequency Band Selectivity test
  •  Spurious emission test

ETSI has issued a standard EN303-413 for end user equipment having GNSS (GPS/GLONASS/BEIDOU) functionality. This standard has become a CE RED requirement. Verkotan provides GNSS testing according to the  ETSI EN303-413 standard.

Purpose of this test is to ensure GNSS functionality fulfills the minimum requirements for interference tolerance. Typical sources of interference are the radios operating at the adjacent frequency bands.

Other GNSS Test Capabilities
GPS Antenna Pattern Test

Our OTA test system provides accurate 3D pictures of GNSS antenna patterns using feed-through method. In addition, we can measure antenna pattern without any cabling using Carrier-to-noise-density-ratio (CNO). Measurements are usually done in Free Space, but we can also use hand, head and body phantoms or even real people to see how your product performs in realistic, different use cases.

Unique GPS Air Performance Test

We will test your device’s full GPS performance with the antenna in a controlled laboratory environment. We have developed a completely new way to test the full GPS performance of a device with the antenna. Our unique GPS Air Performance test lets us test your device’s GPS air performance in any environment you want – for example on the streets of Barcelona, on your favorite jogging route in the park or even in Grand Canyon.

GPS Air Performance Test

Verkotan provides you world’s fastest GPS Air Performance Test for Wearable Devices. Our unique GPS Air Performance test allows us to test your device’s GPS air performance in any environment you want. We have a patent for Testing method and arrangement for GPS Positioning Measurements.

GNSS Raytraced Channel Model

In cooperation with University of Oulu, we studied GNSS signal behavior in urban city. Reflections from buildings make accurate positioning hard for GNSS receivers.

We have visualized satellite signals in the video below. White spots with the numbers are simulated satellites. Green colors are Right-Hand Circular Polarization and Red colors Left-Hand Circular Polarization. Yellow colors are mixture of RHCP and LHCP. The size of the spots represents the signal strength.

GNSS Testing Chamber

In our GNSS testing chamber, we can perform GNSS tests according to ETSI EN3030-413 standard.  We evaluate and verify GNSS device performance with tests such as Antenna Pattern test, Antenna Efficiency, Tracking Sensitivity, Acquisition Sensitivity (hot/cold start), Time to First Fix and Radiated ETSI EN 303 413 Adjacent Frequency Band Selectivity test.

Our test methods allow improving the quality and performance of the product, delivering high-quality results to clients.


This laboratory can be used for 3GPP & SISO and pre-conformance MIMO Measurements. In this chamber, we are able to create a radio environment tailored to client’s needs and test the device in a repeatable and reliable way. It is also utilized for 5G test system solution development and can be used for GNSS, WLAN and IoT testing.
