A45 Antenna

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 between 1.525 - 1.585 GHz with an LNA gain of 30 dB.

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

Mechanical Specifications:
The enclosure is made of an aluminum base with a Lexan™ plastic cap. Dimensions are 4.7 cm in height and 15.2 cm in diameter (1.8 inches by 6.0 inches). The weight is 0.50 kg (1.1 lbs), and it features a 5/8 inch female thread mount with a TNC (straight) RF connector.

Environmental Specifications:
The storage temperature range is -40° C to +85° C (-40°F to +185°F), and the operating temperature range is -40° C to +70° C (-40°F to +158°F). The enclosure has an IP69K rating, and it meets EP455 standards for shock and vibration. Phase center variation is less than 2 mm at GPS L1 for elevations above 15 degrees.

Product Description:
The A45 GNSS antenna is designed for millimeter-level accuracy in land and marine applications. It supports current and future GNSS signals, making it suitable for surveys, RTK positioning, navigation, precise guidance, and machine control. It performs well in challenging environments, offering superior multipath mitigation, stable phase center, and strong SNRs even at low elevations. The ruggedized housing is treated for marine environments and can withstand salt, fog, and spray. It passes the two-meter pole drop test.
