The NovAtel GPSAntenna Model 501 is designed to provide superior
performance over a wide range of GPS applications. It incorporates
the following features:
• L1 Center Frequency at 1575.42 MHz
• Enhanced Multipath Rejection
• Internal Low Noise Amplifier (LNA)
• Internal Interference Rejection Filter
• Low Noise Figure
• Small Size (11.4 cm Diameter x 5.7 cm Height)
• Single External TNC Connector
• Environmentally Sealed Radome
• Tripod 5/8" Coarse Thread Center Mounting
• Four Screw Fixed Mounting (Groundplane or Platform)
General
The GPSAntenna receives the C/A code signals from the NAVSTAR
satellites. These signals are Right Hand Circular Polarization (RHCP)
signals centered at 1575.42 MHz. The antenna module rejects the
unwanted Left Hand Circular Polarization (LHCP) and out-of-band
signals. The antenna then filters, amplifies and transfers the signals to
the GPSCard™ for further processing. Figure 1 shows the typical
antenna Elevation Gain Pattern for RHCP and LHCP signals.
