ETSI EN 303 413 Global Navigation Satellite System Receivers

As a leader in RF regulatory compliance testing, Keystone Compliance’s RF test lab recognizes the requirements needed for wireless radio manufacturers. Meeting the ETSI, FCC, and other wireless testing specifications can be challenging. Not only do we understand the challenges, but we help guide companies through the process. Keystone Compliance actively engages in the TCB Council, ANSI C63 Main Committee, and ANSI C63 wireless working groups.

Our wireless test engineers work with clients to quickly develop appropriate and concise test plans. Keystone takes pride in providing the peace of mind that all of your wireless testing needs will be met. Keystone is continually developing partnerships in GMA and RF exposure testing. These strategic partnerships allow us to meet customer needs beyond our scope of accreditation. Keystone’s radio testing engineers streamline the process and assist companies to achieve the compliance they require.

Summary of ETSI EN 303 413 RF Device Testing Information

This ETSI EN 303 413 wireless product testing document specifies the requirements and methods needed for Global Navigation Satellite Systems (GNSS) user equipment. GNSS user equipment may operate as part of one or more radio navigation satellite service systems.

The global user equipment receives radio signals from one or more GNSS for radio determination of the position, velocity, or other characteristics of an object. GNSS may also include radio determination for the obtaining of information relating to those parameters.

This RF wireless testing document also applies to all user equipment operating in the bands 1164 MHz to 1300 MHz and 1559 MHz to 1610 MHz. The global equipment may operate with the ability to receive any GNSS, GPS, BDS, GLONASS, or SBAS.

It must be noted that this radio equipment document, ETSI EN 303 413, applies to Global User Equipment (GUE) only. For other systems that include a GNSS receiver, the requirements of the most appropriate harmonized standard for that type of equipment apply.

Lastly, other essential requirements that this document does not apply to includes:

  • Marine equipment falling within the scope of council directive 96/98/EC.
  • Airborne products, parts, and appliances falling within the scope of Article 3 of Regulation (EC) No 216/2008 of the European Parliament and the Council.

Scope of ETSI EN 303 413 Testing of Wireless Devices

Technical requirements of ETSI EN 303 413 apply under the environmental profile GUE operations. These operations are most likely going to be stated by the manufacturer. The GUE must comply with all the technical requirements of this document when operating within the boundary limits of the manufacturer’s declared environmental profile.

The test defines environmental conditions that must be carried out at representative points. These are needed to be within the boundary limits of the operational environmental profile. 

Where technical performance varies, tests are carried out under a sufficient variety of conditions. This will assist in giving confidence of compliance for the affected technical requirements. 

Unless otherwise stated, the normal temperature and humidity conditions are as follows:

  • Temperature: 15 to 35 degrees Celsius
  • Relative humidity: 20% to 75%

ETSI EN Wireless Regulatory Compliance Testing Conditions

For simplicity and accuracy, conducted testing is performed. If this is not possible, radiated testing is used.

The following test equipment is used and recommended for performing this test:

  • GNSS signal generator. This must be capable of simulating the GNSS constellations and GNSS signals.
  • RF signal generator. The equipment must be capable of generating adjacent frequency signals.
  • Filter for ensuring the test is not adversely affected by the RF signal generator.
  • RF power combiner. This is used to combine the GNSS signal(s) and the adjacent frequency signal.
  • A means for establishing the RF power of the test signals at the input of the equipment under testing.
