Product Description:

High-Precision Anti-Jamming Anti-Spoofing TK2

Product Features

1. Multi-mode high-precision positioning. Accuracy <1 m without being jammed, and 0.5–5 m with being jammed.

2.Active cancellation for GNSS jamming, fully analog, low power and low latency.

3.Adaptive narrowband filtering against full-band VCO sweep jamming for agile suppression.

4.Baseband signal timingly analysis, identifying and eliminate GNSS spoofing signals.

5.Multi-element antenna with adaptive beamforming to block interference from below the horizontal plane.

6.Low power consumption, can be powered directly by the flight controller without extra power supply

TK2 Comparison with Multi-Element Adaptive Nulling Receiver CRPA

• Antennas Compared : L1 four-element nulling antenna CRPA, B3 four-element nulling antenna, and TK2.

• Measurement Setup:

Since the nulling antennas CRPA have relatively narrow bandwidths that cover only part of the GNSS frequency spectrum, while the TK2 covers the entire GNSS band, the following setup was used to enable fair comparison of anti-jamming performance within the same frequency range:

When compared with the L1 nulling CRPA antenna, the L2, L5, and other lower-frequency bands of TK2 were disabled.

When compared with the B3 nulling CRPA antenna, the L1, B1, and other higher-frequency bands of TK2 were disabled.
