Product catalog summary

Specifications:
The GNSS sensor supports multiple signals including GPS L1/L2/L5, GLONASS G1/G2, BeiDou B1/B2/B3, SBAS, L-band, and Galileo E1/E5a and b. It operates within GNSS frequencies of 1.165 to 1.278 GHz and 1.525 to 1.615 GHz. The LNA gain is 30 dBn with a typical noise figure of 2.0 dB. The L-band sensor operates at frequencies from 1.525 to 1.585 GHz with an LNA gain of 30 dB.

Power:
The device requires an input voltage ranging from 3.3 to 15 VDC and a typical input current of 25 mA.

Mechanical:
The enclosure is made of an aluminum base with a Lexan™ plastic cap, measuring 4.7 cm in height and 15.2 cm in diameter, and weighing 0.50 kg. It features a 5/8 inch female thread mount and a TNC (straight) RF connector.

Environmental:
The antenna can be stored at temperatures between -40°C to +85°C and operates between -40°C to +70°C. It has an enclosure rating of IP69K and meets EP455 shock/vibration standards. The phase center variation is less than 2 mm at GPS L1 for elevations above 15 degrees.

Applications:
The A45 GNSS antenna is designed for millimeter-level accuracy in land and marine applications. It supports current and future GNSS signals and is suitable for surveys, RTK positioning, navigation, precise guidance, and machine control. It performs well in challenging environments, offering superior multipath mitigation and stable phase center. The ruggedized housing is marine-prepared and withstands salt, fog, and spray, passing a two-meter pole drop test.
