Securing pure and clean signals

Making the case for XF technology to enhance GNSS reliability

In today’s world, the radio frequency (RF) spectrum is more crowded than ever with signals from Bluetooth, Wi-Fi, cellular networks, and more. This congestion poses a significant threat to the clear reception of Global Navigation Satellite System (GNSS) signals, crucial for various applications from autonomous vehicles to precision agriculture.

The interference primarily stems from LTE and 5G mobile networks, as well as satellite communication services, that closely encroaching on GNSS frequencies. Interference, out-of-band and in-band, degrades signal quality, impacting critical industries reliant on precise GNSS data.

Traditional GNSS antennas struggle to filter out this interference effectively, leading to compromised performance. This is where innovative solutions like eXtended Filtering (XF) technology come into play. XF technology, developed by Calian, tackles out-of-band interference, which helps provide uninterrupted GNSS reception.

Key market drivers, including the expansion of mobile networks and satellite communication services, highlight the urgency for advanced filtering solutions like XF technology. Additionally, regulatory bodies increasingly mandate stringent requirements for GNSS signal integrity, further emphasizing the need for robust solutions.

Calian’s XF antennas employ double-hump filtering at the input of the antenna’s Low Noise Amplifier (LNA), protecting subsequent amplifier stages from interference. This proactive approach ensures clean GNSS signal reception even in challenging RF environments.

While ideal bandpass RF filters face practical limitations, Calian’s XF technology strikes a balance between interference mitigation and signal fidelity. By incorporating LNAs with excellent linearity characteristics and utilizing advanced RF filtering techniques, Calian XF antennas offer reliable GNSS reception across diverse applications.

In an era where RF congestion continues to escalate, proactive measures are essential to safeguard the integrity of GNSS signals. Calian’s XF technology represents a clinical solution, helping to provide a pure and uninterrupted GNSS reception amidst the increasingly crowded RF spectrum.
