Detailed description

Tallysman TW3972 GNSS antena, siūloma Pixel sur Mer, skirta jūrinėms ir sausumos taikymams, reikalaujanti aukštos pozicionavimo tikslumo. Naudojanti Accutenna® technologiją, ši antena užtikrina išplėstą GNSS žvaigždžių dangaus dangos aprėptį, įskaitant GPS L1/L2/L5, GLONASS G1/G2/G3, BeiDou B1/B2/B2a, Galileo E1/E5a+b, NavIC L5 bei L-band ir SBAS (WAAS, EGNOS, MSAS, GAGAN) pataisų paslaugas. Ypač tinka trispalvėms RTK ir PPP imtuvams.

Techniniai parametrai ir patvarumas

TW3972 išsiskiria dviem dvigubai sudėtais, dvigubai maitinamais strypiniais elementais, tiksliai suderintais. Abiejų ortogonalių maitinimų signalai yra sujungiami ir stiprinami plačiajuosčiu LNA, po to siaurai filtruojami kiekvienai juostai prieš sujungimą. Šis dizainas užtikrina didesnį daugkartinio signalo atmetimą, tiesinį fazės atsaką ir labai mažą fazės centro poslinkį (PCV). LNA stiprintuvo triukšmo koeficientas labai mažas (< 2,5 dB tipinis) ir stiprinimas didelis (37 dB tipinis), optimizuojant signalo/ triukšmo santykį. Įmontuotas tvirtas priešfiltras slopina LTE ir mobiliojo ryšio juostų, įskaitant Ligado, trukdžius.

« Tallysman TW3972 antenna: triple-band GNSS precision for extreme environments »

The Tallysman TW3972 antenna is a critical component for high-precision GNSS systems, particularly in professional and autonomous maritime applications. Its full triple-band support (L1/L2/L5, G1/G2/G3, E1/E5a+b, B1/B2/B2a, L5 NavIC) and L-band correction services ensure compatibility with current and future GNSS constellations, delivering robust and redundant positioning data. This is essential for RTK and PPP solutions requiring centimeter-level accuracy.

The antenna’s design, incorporating Accutenna® technology, provides exceptional multipath rejection and minimal phase center variation (PCV). These features result in more stable and precise positions in complex environments such as urban areas or near reflective surfaces on vessels. The integrated LTE/cellular interference pre-filter is a significant advantage, preserving signal integrity where other antennas may fail. Its IP67/IP69K rating, combined with MIL-STD and European railway shock, vibration, and salt fog certifications, confirms its suitability for continuous operation in extreme marine conditions.

With consistent performance across a wide voltage range (+2.5 to 16VDC) and low current draw (24 mA typical), the TW3972 simplifies power management. Its standard through-hole mounting and support options (bracket/mast) offer versatile installation possibilities. This antenna is an ideal front-end for high-end inertial navigation systems such as the SBG Ellipse D, providing the raw GNSS data quality required for sensor fusion and precise navigation algorithms, thereby enhancing overall system performance and reliability.

Frequently asked questions

Need help? Contact us

Which GNSS constellations does the TW3972 antenna support?

The Tallysman TW3972 antenna supports a wide range of GNSS constellations and correction services. It covers:

GPS: L1, L2, L5GLONASS: G1, G2, G3BeiDou: B1, B2, B2aGalileo: E1, E5a+bNavIC: L5As well as L-band and SBAS correction services (WAAS, EGNOS, MSAS, GAGAN).It is specifically designed for triple-frequency precision positioning.

What type of mounting is recommended for the TW3972 antenna?

The TW3972 antenna is designed for permanent installation via a ¾” (19mm) through-mount. For installations not on a roof, a ground plane of 100mm is recommended.

Optional mounts such as an L-bracket (part number 23-0040-0) or a pipe mount (part number 23-0065-0) are also available for alternative mounting options.

Is the TW3972 antenna weather-resistant?

Yes, the TW3972 antenna is housed in a watertight and robust enclosure compliant with strict environmental standards. It holds an IP67 rating, making it resistant to water and dust. It is designed to operate across a wide temperature range, from -40°C to +85°C.

Additionally, it complies with RoHS, RED, and REACH standards and has passed salt fog resistance tests (MIL-STD-810F Section 509.4), shock tests (50 G vertical axis, 30 G other axes), and vibration tests (3 axes, 3 G).

What are the power supply specifications for the TW3972 antenna?

The TW3972 antenna operates within a supply voltage range of +2.5 to 16 VDC (nominal, up to 50 mV peak-to-peak ripple). Current consumption is typically 24 mA at 25°C. It also features electrostatic discharge (ESD) protection rated at 15 kV (air discharge).

Is the TW3972 antenna compatible with RTK receivers?

Yes, the TW3972 antenna is specifically designed for high-precision positioning applications. It is ideal for triple-frequency RTK (Real-Time Kinematic) receivers as well as PPP (Precise Point Positioning) systems, providing high accuracy for demanding applications such as precision agriculture or autonomous vehicle guidance.

How does the TW3972 antenna handle interference from external signals?
