NovAtel’s 42G1215A-XT-1-Cert is a dual-frequency, compact GPS antenna. It can be used for GPS L1 only or L2 dual-frequency applications. This enhances flexibility and decreases costly duplication of equipment.

Special advantages of dual-frequency systems are: Modeling and reduction of ionospheric errors affecting all GPS observations because two satellite observations can be combined; and resolving RTK ambiguity faster.

Although its compact size is conceived of for use in airplanes, it will also operate in mobile environments.

The 42G1215A-XT-1-Cert meets the Restriction of Hazardous Substances established by the European Union. Thus, it can be integrated into system designs well into the future.
