The NovAtel GPSAntenna Model 501 is designed to provide superior
performance over a wide range of GPS applications. It incorporates
L1 Center Frequency at 1575.42 MHz
Enhanced Multipath Rejection
Internal Low Noise Amplifier (LNA)
Internal Interference Rejection Filter
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)
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.
Gain Pattern > 0 dBic to 75 from vertical
> -3 dBic to 85 from vertical
< -10 dBic 120 from vertical Polarization Right hand circular at all angles above t horizon Axial Ratio <> 10 dB
Phase Center Stability <>15 dB for f > 1715 MHz
