Optimizing geodetic antennas: Precision calibration and multi-path minimization
Geodetic quality antennas require a precise calibration, that estimates the phase centre offset at various frequencies (GPS L1, L2 and L5 are typical). In addition to the phase centre offset, the phase centre variation as a function of azimuth and elevation angle is also calibrated, enabling the observations to be adjusted correctly. Additionally, to minimize multi-path choke ring antennas may be a required option.
Precision positioning: Enhanced coverage and signal quality
- Accurate and precise positioning with Calian’s patented antenna technology
- Multi constellation coverage to maximize the number of observations available for position and time estimation (GPS, QZSS, GLONASS, Galileo, and BeiDou)
- Multi-signal and multi-band support
- Multi-path mitigation and/or excellent axial ratio with choke ring option
Advanced antenna features: Calibration, compatibility, and durability
- Optional pre-filters to enhance out-of-band signal rejection
- IGS and NGS calibrated antennas
- Wide voltage range for broad receiver compatibility
- Various Low Noise Amplifier (LNA) gain options to support long antenna cable runs
- Strong electro-static discharge immunity
- Rugged construction
