What is GNSS User Equipment?

GNSS User Equipment receives signals from GPS, GLONASS, Galileo, or BeiDou satellite constellations to determine position, velocity, or time. Products include standalone GPS receivers, vehicle navigation units, fleet tracking devices, drone flight controllers, wearables with GPS, and modules integrated into smartphones and IoT devices.

Most modern GNSS products also include additional wireless radios — see IoT Device Testing for multi-radio certification, and NVLAP wireless testing services for all radio technologies covered in a single visit.

🔎 Why emissions limits matter for GNSS: GPS L1 signals arrive at approximately −130 dBm — far below the noise floor of most RF environments. Even small spurious emissions from nearby electronics can degrade receiver sensitivity. Use our pre-compliance testing service to identify problems before formal certification.

Wireless Radio Testing for Combination GNSS Devices

The vast majority of GNSS-enabled products include at least one additional radio. Compatible Electronics tests all of them under one roof, eliminating the need to coordinate multiple labs.

EMC Immunity & RF Exposure

GNSS devices intended for EU CE marking under the Radio Equipment Directive must also demonstrate immunity. Compatible Electronics performs the full IEC 61000-4 series: ESD, Radiated RF, EFT, Surge, and Conducted RF. Generic standards IEC 61000-6-3 and IEC 61000-6-4 are available where applicable.

GNSS devices with active transmitters also require RF exposure (SAR/MPE) evaluation. See RF Exposure Testing for FCC, IC RSS-102, and ETSI requirements, and FCC wireless charging & RF exposure guide in the Learning Center.
