navXperience 3G+C Defense
The 3G+C Defense is a four constellation GNSS antenna built for military applications.
The production of the 3G+C series meets high quality standards with respect to processes and materials used. The housing material is designed to be extremely durable, UV resistant and color true. Even after years of use it will appear like new. The upper and lower housing are laser-welded to ensure that neither air, dust, nor water can penetrate its interior, even at pressure differences of 2.5 bar (36 psi). This is also true for the standard TNC connector. Because it is integral to the case and was specifcally designed for this housing. Thus, the 3G+C series complies with IP69k and all tests of MIL-STD 810g.
One of the antennas numerous advantages is excellent reception of satellites at low elevations, i.e. weak GNSS signals. This is an outstanding property, because the reception characteristics for these satellites are generally poor due to a longer path through the atmosphere.
The 3G+C antenna enables weak signal tracking of GNSS satellites to the horizon (0° elevation) with sufficient quality, while other high-precision antennas typically lose track at 7° elevation or are providing such poor signal quality that the GNSS receiver cannot use it.
This unique attribute of the 3G+C antenna results in improved productivity for the user, because it will enable more satellites being tracked and faster positioning with better signal quality (C/No).
In applications experiencing roll and pitch motion, such as machine control or on-board of ships, low elevation satellite tracking with good signal quality allows the GNSS receiver to determine its position more accurately and with less noise.
The use of expensive RF filters, with sharp roll-offs, as part of the LNA, makes this antenna less sensitive to jamming and interference.
This antenna has successfully passed all pertinent requirements of MIL-STD 810g.
