42G1215A-XT-1-2-Cert Compact Dual-Frequency GPS Antenna


Formerly the ANT-A72GLA-TW-N.

The 42G1215A-XT-1-2-Cert is an active L1/L2 dual-frequency GPS plus L-Band tracking antenna. It is aircraft certified for navigation but suitable for any mobile application. Customers can use the same antenna for L1 only or dual-frequency applications to increase flexibility and reduce equipment costs. L-Band offers real-time Differential GPS (DGPS) positioning with metre to decimetre level accuracy.

Small Form Factor

This small form factor antenna measures 76 mm in diameter by 119 mm in length, accepts an input voltage of 2.5 to 24 VDC and consumes less than 35 mA. It is compact and lightweight, making it highly portable and suitable for a variety of environments and applications.

Suitable For Dual Frequency GPS Systems

The ANT-A72GLA-TW-N antenna is suitable for use in applications using GPS L1/L2 dual-frequency systems. There are two major advantages with dual-frequency systems: Ionospheric errors that are inherent in all GPS observations can be modeled and significantly reduced by combining satellite observations made on two different frequencies. And observations on two frequencies allow for faster RTK ambiguity resolution.


Meeting the European Union’s directive for Restriction of Hazardous Substances (RoHS), integrators can be confident the ANT-A72GLA-TW-N can be used in system designs for years to come.
