The ANT-A71GLA4-TW is an active L1 GNSS antenna, offering combined GPS + GLONASS signal reception plus L-Band tracking. It is aircraft certified for navigation but is suitable for any mobile application. Customers can use the same antenna for GPS only or dual-constellation applications to increase flexibility and reduce equipment costs.



Small Form Factor

This small form factor antenna measures 76 mm in diameter by 119 mm in length. It is compact and lightweight, making it highly portable and suitable for a variety of environments and applications.

Suitable For GNSS Single Frequency Systems

The ANT-A71GLA4-TW antenna is suitable for use in applications using GPS or GPS + GLONASS L1 single-frequency. L-Band offers real-time Differential GPS (DGPS) positioning with metre to decimetre level accuracy. NovAtel’s GL1DE® algorithm optimally combines L1 code and L1 phase data to produce a positioning solution well suited for applications such as agricultural guidance, where pass-to-pass repeatability is critical.


Meeting the European Union’s directive for Restriction of Hazardous Substances (RoHS), integrators can be confident the ANT-A71GLA4-TW can be used in system designs for years to come.
