GNSS antennas

TW8889 | Dual Band Antenna

These high performance antennas have been especially chosen for their excellent performance/size compromise.

The TW8889 provides multi-constellation tracking capabilities, supporting a range of satellite systems including GPS L1/L2, GLONASS G1/G2/G3, BEIDOU B1/B2, GALILEO E1/E5b, and SBAS (WAAS/EGNOS/MSAS) signals.

Antenna usage for RTK, PPP and PPK

While this antenna offers a great mix of size and performance, they are not recommended for applications where reliable RTK, PPP or PPK is required.

They are however very good in standalone/SBAS GNSS.

We provide only the flat radome version of the antenna.

Both the flat and conical radome have same performances. The conical radome is useful for applications where there is a risk for the accumulation of a substance on top of the antenna (such as snow).

VSP6037L and VSP6037L-MAR | Verostar Survey Grade Antenna

The VSP6037L is a survey grade antenna, capable of tracking all signals in view, and featuring maximal performance when centimeter level precision matters.

The VSP6037L-MAR is a special version of the VSP6037L with extra filtering that provide enhanced Iridium and Inmarsat signal rejection. Those signals which are typically found onboard large vessels or in harbors are close to GNSS signal and can disturb it.

Aside from this difference, both versions of the antenna share the same characteristics.

Those antennas feature a tight phase center variation and can be mounted on any standard survey mount with its 5/8"-11 UNC threaded hole.
