NovAtel 3GOXX16A4-XTR-1-1-Cert TSO Certified Compact Dual-Frequency GPS Antenna

The 3GOXX16A4-XTR-1-1-CERT (formerly the ANT-35C2GA-TW) from NovAtel has reached End of Life (EOL). Please contact us for a suitable replacement antenna.



The 3GOXX16A4-XTR-1-1-Cert from NovAtel (formerly the ANT-35C2GA-TW) is an active L1/L2 GPS antenna. This antenna was designed for airborne use, but is suitable for any mobile application.

NovAtel’s compact 3GOXX16A4-XTR-1-1-Cert antenna offers dual-frequency GPS capability. Because it handles both L1 only and L2 dual-frequency GPS applications, it is flexible in use and reduces expenditure for equipment.

Dual-frequency systems have special benefits. When two different satellite observations are made it is possible to model and reduce the ionospheric errors that affect GPS observations negatively. In addition, it is possible to resolve RTK ambiguity faster.

While the unit was conceived of especially for use in helicopters and airplanes, its feather weight and small size also makes it convenient in mobile operations.

The 3GOXX16A4-XTR-1-1-Cert is certified according to the European Union’s standard for Restriction of Hazardous Substances. This means it is capable of being integrated into future system designs for a long time to come.
