    NovAtel Inc. has introduced the GPS-713 pinwheel antenna, available in two configurations: the standard GPS-713-GGG-N and the L-Band capable GPS-713-GGGL-N. 

    Both antennas provide enhanced Inmarsat interference rejection, allowing tracking of GNSS signals in the presence of high-powered Inmarsat transmitters typically found on marine vessels. The antennas receive GPS L1, L2, L5; GLONASS L1, L2, L3; BeiDou B1, B2; and Galileo E1, E5a/b frequencies, optimizing global satellite tracking capabilities. Customers can use either antenna for GPS-only or multi-constellation applications, providing excellent flexibility and reduced equipment costs, NovAtel said.

    Designed for baselines of any length and easy installation, the phase center offset of these antennas remains constant as the azimuth and elevation angle of the satellites change. The antenna shares the same form factor as other NovAtel GPS-700 series antennas, and is enclosed in a durable, waterproof housing.  Its compact, lightweight size makes it suitable for a wide variety of environments and applications.

    NovAtel, Inc., has introduced the GPS-702-GG-HV to its line of high-performance Pinwheel antennas. Tracking L1/L2 GPS and L1/L2 GLONASS frequencies, customers can use the same antenna for GPS-only or dual constellation applications, reducing equipment costs and need for future redesign, the company said.

    With the same form-factor and choke ring performance as the company’s other pinwheel antennas, the GPS-702-GG-HV has been enhanced even further to provide the robustness needed for use under high-vibration conditions.

    The phase center of the antenna remains constant as the azimuth and elevation angle of the satellites change. Signal reception is unaffected by the rotation of the antenna or satellite elevation, so placement and installation of the antenna can be completed with ease. With the phase center in the same location for both the L1 and L2 signals and with minimal phase center variation between antennas, this antenna is designed for baselines of any length.

    Enclosed in a durable, waterproof housing, the GPS-702-GG-HV comes in three colors: NovAtel standard grey, as well as desert tan and olive drab for military customers. The antenna is available for order beginning September 12.
