Product catalog summary

Specifications:
The A45 GNSS antenna supports multiple GNSS 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 Requirements:
The antenna requires an input voltage ranging from 3.3 to 15 VDC and a typical input current of 25 mA.

Mechanical Features:
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 (1.8 inches by 6.0 inches). It weighs 0.50 kg (1.1 lbs) and features a 5/8 inch female thread mount and a TNC (straight) RF connector.

Environmental Specifications:
The antenna can be stored at temperatures between -40° C to +85° C (-40°F to +185°F) and operates between -40° C to +70° C (-40°F to +158°F). 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 and Features:
The A45 GNSS antenna is designed for millimeter-level accuracy in land and marine applications, supporting current and future GNSS signals. It is suitable for surveys, RTK positioning, navigation, precise guidance, and machine control. The antenna is effective in challenging environments, offering superior multipath mitigation, stable phase center, and strong SNRs even at low elevations. The ruggedized housing is pretreated for marine environments, resistant to salt, fog, and spray, and can withstand a two-meter pole drop test.
