Global Navigation Satellite Systems Testing Services: EN 303 413
Global navigation satellite system (GNSS) is a general term describing any satellite constellation that provides positioning, navigation, and timing (PNT) services on a global or regional basis. While GPS is the most prevalent GNSS, other nations are fielding, or have fielded, their own systems to provide complementary, independent PNT capability.
Test Criteria & Methods
EN 303 413 is the standard for Global Navigation Satellite System (GNSS) receivers, operating at 1,164 MHz to 1 MHz and 1,559 MHz to 1,610 MHz, including GPS, GLONASS, Beidou and all current civilian navigation satellite system products.
Based on the requirements listed in EN 300 440, this version introduces the selective testing of adjacent frequency bands, which requires the evaluation of all GNSS modes and frequency bands supported by the product, taking into account the product's C/N0 (carrier/noise density ratio). Therefore, before the product is certified, the laboratory needs to know in advance the mode and frequency band of the GNSS supported by the product, as well as the monitoring method of C/N0.
- Confirmed GNSS type & Frequency band
|GNSS TYPE||GNSS SIGNAL NAME|
|GPS||L1, L2, L5|
|Galileo||E1, E5a E5b, E6|
- Relevant C/N0 monitoring software (ie, TEQC, BNC, LeicaGNSSQC, GPSTK, GPSToolbox, u center) and specific methods for monitoring (ie, communication between products) and PC software through UART or other communication interface (for mobile phones or tablets that is operated by Android)
