Tallysman, a manufacturer of high-performance GNSS antennas, has introduced two additions to its VeraPhase line of precision antennas. The VP6300 is a triple-band antenna for reception of GPS L1/L2/L5, GLONASS G1/G2/G3, BeiDou B1/B2 and Galileo E1/E5a+b (1165MHz to 1254MHz + 1560MHz to 1610MHz). The VP6200 is a dual-band antenna for reception of GPS L1/L2, GLONASS G1/G2, BeiDou B1/B2, Galileo E1 and the L-Band correction services (1195MHz to 1254MHz + 1525MHz to 1610MHz). Both antennas have been calibrated by the U.S. National Geodetic Survey (NGS) and are designed for high-precision applications such as real-time kinematic (RTK), precise point positioning (PPP) and other applications where precision matters. For OEM manufacturers, the antennas feature an available, uncommitted printed circuit board (PCB) for integration of custom electronics such as precision GNSS receivers. According to Tallysman, these antennas fill out the VP6x00 product family with precision at a cost-effective price point. Both of these new products feature the same patented VeraPhase technology as in the VP6000 all-band reference antenna. VeraPhase technology is proven to have the lowest axial ratios from horizon to horizon across all frequencies, very tight Phase Centre Variations (PCV), superior gain and extremely high efficiency. The new antennas feature a highly linear LNA with robust pre-filtering to minimize desensing from high-level out-of-band signals such 700MHz LTE and other cellular band signals.
